    5. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 i Summary The sites excavated at Barnacragh E2446 comprised a burnt mound, trough, stake-holes and a pit. Charcoal yielded an Early Bronze Age date, in common with material from other burnt mound sites nearby. This is one of five Bronze Age sites excavated along this portion of the new road. The recovery of probable Mesolithic artefacts in secondary contexts is a significant addition to the known distribution of Mesolithic material in Galway.

    6. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 1 Introduction This report comprises the final excavation report for a burnt mound found at Barnacragh, Co. Galway during archaeological testing within the lands acquired for the new N6 Galway to Ballinasloe dual carriageway road scheme (O’Donoghue et al. 2006). The site comprised a spread of burnt mound material, a trough, stake-holes and a pit. Charcoal from the site yielded an Early Bronze Age radiocarbon date. 2 Site Location, Topography and Soils The site was located in the townland of Barnacragh at NGR 181170 228507. The site was situ- ated within an area of flat, low-lying ground surrounded by gently undulating terrain (Plate 1). The solid bedrock is Middle to Upper Carboniferous Limestones, with Calp Limestones predominating in the area of this site. The Quaternary deposits in the region are undulating glacial drift with some post-glacial peat and alluvial deposits. Trial pitting for the Environ- mental Impact Assessment report indicated that the subsoil in the area of this site at Barnac- ragh included both sand and gravel with some clay. The large flat areas of land represents the remains of wetlands and open waters which were reclaimed by drainage works were probably undertaken in the 19th and 20th centuries. The burnt mound was located near an esker, a sand and gravel ridge composed of glaciofluvial sediments that was laid down by rivers formed from glacier meltwater. This esker was aligned east to west and c. 20 m to the north there was a palaeochannel which was filled by peat de- posits. As peat accumulated it covered the entire burnt mound which was found at the south- ern edge of the palaeochannel. The site was located on soils classified as grey brown podzolics, with associat ed brown earths, gleys and basin peat. These soils have a moderately wide use range and are good for cereal, fruit and vegetable cultivation (Gardiner & Radford 1980). 3 Background to the Development The excavation was undertaken by Eachtra Archaeological Projects for Galway County Council and the National Roads Authority and forms part of wider archaeological excavation programme undertaken by Eachtra within approximately 15 km of the proposed N6 Galway to Ballinasloe dual carriageway scheme (Contract 4, Figures 1-3).

    7. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 4 Archaeological and Historical Background 4.1 Prehistoric period Mesolithic material has now been identified from a small number of sites in western Con- nacht and in particular material has been identified on the major river and lake systems. Lough Corrib stands out as a centre of outstanding importance for looking at both Mesolith- ic settlement and the Mesolithic/Neolithic transition (Gibbons et al. 2004). The artefactual location bias suggests that the Lough Corrib catchment area was a population centre in the later Mesolithic period. The finding of a Bann flake at Oranmore confirms that there was a human presence to the east of the Corrib in the late Mesolithic. No definite Mesolithc site has as yet been identified in east Galway but there are flint artefacts that probably date to the Mesolithic from burnt mound sites excavated by Eachtra Archaeological Projects at Barnac- ragh (E2446) and Urraghry (E2449). The Neolithic or new stone age began around 4000 BC when the first farmers came in search of pasture for their livestock and arable land in which to grow their grain. Ireland was then heavily forested so it was necessary for these farmers to engage in forest clearance. This they did with polished stone axeheads hafted in wooden handles. A number of stone axes have been recovered from along the valley of the river Suck and around the Ballinasloe area in general (Henry 1992, 37-38), indicating activity in the area during the Neolithic. The Neolithic period also saw new developments in ritual activity, in particular the build- ing of megalithic tombs. Only seven Neolithic tombs are recorded for the whole of north Galway (as defined by Vol 2 of the Archaeological inventory of Co. Galway), which includes the barony of Clonmacowen, and these are limited to court tombs and wedge tombs (Alcock et al. 1999, 1). There is no published inventory for south Galway. No megalithic tombs are recorded from the area around Balinasloe and Aughrim; the closest concentration is a group of four tombs identified around the limestone plains of Monivea. The erection of large more or less unhewn stones, often in prominent locations, was a wide- spread custom in prehistoric Ireland and elsewhere in western Europe. These take the form of stone circles, stone rows, stone pairs and single or isolated standing stones. Single standing stones may have had a wide variety of uses ranging from route or boundary markers to burial memorials. Two standing stones (RMP GA098:031 and GA087:023) are located around Aughrim, one of which is reputed to be associated with a stone axehead (Alcock et al. 1999, Permalink: http://eachtra.ie/index.php/journal/e2446-barnacragh-co-galway/ 2
    8. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 17). During the Bronze Age metal was extracted and worked for the first time. Bronze Age axes and a dagger have been found in the area round Ballinasloe and a bronze spear head (NMI 1986:19) and dirk (NMI 1986:16) were recovered from the river Suck during drainage opera- tions in the 1880s (information from the National Museum of Ireland Topographical files). Underwater investigation of the site of Correen Ford, on the river Suck, identified a Late Bronze Age sword which was found close to a portion of a pottery vessel, perhaps of the same age (Kelly 1989). Coreen Ford was probably one of the main crossing points on the Suck in prehistory and early history. A variety of burial monuments date to the Bronze Age period, including cairns, tumuli and barrows. A cairn is a mound of stone often used to cover burials, and a tumulus is a mound of earth used for the same purpose. Barrows are burial monuments which usually consist of a circular central area, which may be flat or slightly dished (a ring ditch), or domed (a ring barrow), and which is enclosed by a ditch and occasionally by an external bank. Excavated Bronze Age burials include interments in cists, in pits lined with stone flags, and in simple pits, some of which were accompanied by pottery or other grave goods. These can be placed in tumuli, cairns or barrows, but can also be set within ‘natural’ monuments, such as sand ridges, or can appear in flat cemeteries, with no above ground marker at all (Waddell 1990, 1). A total of 22 cairns and tumuli, 10 isolated cist and pit graves and 31 barrows are known from north Galway (Alcock et al. 1999, 4 & 12). A significant concentration of Early Bronze Age features can be recognised in the area between Athenry, Tuam and Headford; however, very few burials or cairns have been identified in the areas around Ballinasloe and Aughrim. The most common Bronze Age monuments are burnt mounds. They are represented by small mounds of burnt stone, which were fired in order to heat water in a pit dug into a marshy area, the stones being discarded once they had cooled. The function of these monuments has been the source of much debate with various theories being expounded including cooking, washing and relaxation. Two burnt mounds (087:175B and 087:175C) lying in close proxim- ity to each other have been identified in Loughbown townland and two other newly recorded sites at Cooltymurraghy (E2448) and Urraghry (E2449), as well as this site at Barnacragh (E2446), have been excavated during the course of the present excavation programme.

    9. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 Bronze Age settlement site (E2445) was also excavated in Mackney townland and Bronze Age dates were retrieved from another site in Mackney (E2443). These are important additions to the recorded prehistoric landscape in east Galway. We know almost nothing of Irish Iron Age settlement and burial outside the major complexes of royal ritual sites and a small number of burial sites that may be Iron Age in date. Deficien- cies in our knowledge of the settlements and habitations of ordinary people are so marked that Raftery referred to the majority of the population as the ‘invisible people’ (1994, 112). The majority of the evidence for the Iron Age period consists of finds of La Tène decorated metalwork and some pieces of stone sculpture. Examples of La Tène artefacts/monuments from east Galway include the Turoe Stone located close to Loughrea and a Late La Tène metal artefact found at. Rahally hillfort. This hillfort was excavated along the route of the new N6 Galway to Ballinalsoe road (Contract 3) and the evidence indicates settlement in prehistoric and medieval times (Mullins in progress). Iron Age radiocarbon dates were ob- tained from excavations at an enclosure site at Loughbown 2, also excavated along the route of the new N6 Galway to Ballinasloe road (Contract 4). However, medieval dates were also obtained from Loughbown 2 and the exact nature of occupation at the site during the Iron Age is uncertain. 5 Results of Excavation This site comprised a trough, the remains of a mound of charcoal-rich material and heat-shat- tered stone, 69 stake-holes and a shallow pit, all found within an area of excavation measuring c. 255 sq. m (Figures 4 and 5). Full details are available in the stratigraphic index (Appendix 1), the stratigraphic matrix (Appendix 2) and the groups and sub-groups text (Appendix 3). 5.1 Trough The trough (C.6) was found beneath the spread of burnt mound material (C.5). It was cut into an alluvial silt deposit (C.78) and the glacial till (C.2) beneath it. The northern part of the trough was sub-circular and measured 2.39 m long by 2.2 m wide and 0.38 m deep. The total capacity was 1.99 cubic metres. A linear cut extended from the southern part of the trough for a distance of 1.8 m. It was 0.8 m wide and 0.4 m deep. This may have aided emptying the trough after use (Plate 2). Permalink: http://eachtra.ie/index.php/journal/e2446-barnacragh-co-galway/ 4
    10. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 The trough was filled by a basal organic layer (C.7) of peaty sediment with some fragmentary timbers. This was overlain by a deposit of charcoal and heat-shattered stone (C.5), which spread beyond the confines of the trough and constituted the main deposit of burnt mound material. The backfill or slump in the trough was overlain by a deposit of peat (C.3) with frequent fibrous root and reed inclusions. This formed naturally when the site was no longer in use and it indicates that the area was often waterlogged. This suggests that the trough was self-filling. 5.2 Mound A spread of charcoal and heat-shattered stone (C.5) measuring 5.8 m by 2.35 m was identi- fied (Plates 3 and 4). This material was a maximum of 0.34 m in height and appeared to be homogenous throughout. There was one find from the mound, a typical Bronze Age convex scraper (E2446:5:2, Appendix 4). The typology of this artefact corresponds to the Bronze Age radiocarbon date that was obtained from this site. There were two isolated shallow, charcoal-rich spreads of heat-shattered stone that were prob- ably a continuation of the main mound. The first spread (C.66) measured 0.5 m in length, 0.46 m in width and 0.2 m in height and it was located 1.5 m to the east of the main mound of material. The second spread (C.89) measured 2.6 m in length, 2.4 m in width and 0.1 m in height and was located 2.5 m north of the trough (C.6). 5.3 Stake-holes There were 69 stake-holes excavated at the site (12 within the trough and 57 under the burnt material to the north-west of the trough). A curvilinear arc of stake-holes was 5 m in length and made up of 57 stake-holes (C.14, C.16, C.18-C.64, C.67, C.70, C.72-74, C.76, C.156, C.157 and C.159). It ran from the trough along the contour line to the north-west (Plate 5). The arc was formed by a central line of vertically placed stake-holes, flanked on either side by supplementary stakes-holes that were angled towards the central stakes. The impression is that the central line needed support. The structure may have been load-bearing, but the stake-holes were very narrow and it may simply have acted as a screen, protecting against the prevailing wind, which required repeated support.

    11. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 The remaining 12 stake-holes (C.76, C.77, C.79, C.80, C.81, C.82, C.83, C.84, C.85, C.86, C.87 and C.88) were found within the trough and they may originally have been supports for holding the lining of the trough in place. 5.4 Pit A shallow circular pit (C.9) was located to the south-west of the trough and the burnt mound. It measured 1.36 m in length, 1.30 m in width and 0.26 m deep and it contained three fills (C.10, C.11 and C.12) but there was no indication of the original function of the pit. 5.5 Lithics The lithics assemblage was examined by Farina Sternke (Appendix 4). It consisted of a flint blade (E2446:1:1) recovered from the topsoil and a chert scraper (E2446:5:2) found in the burnt mound material. These were the only artefacts retrieved from the site. The retouched flint blade (E2446:1:1) was most likely produced using a soft hammer stone. Based on tech- nology and typology it probably dated to the Early Mesolithic period, possibly a slightly anomalous form of a rather broad Early Mesolithic needle point (Plates 6 and 7). The re- touched flake (E2446:5:2) was a good example of a typical Bronze Age convex end scraper, the result of a platform technology which used a soft to medium stone on a homogenous, fine-grained black chert (Plate 8). 5.6 Charred plant remains A total of 11 samples from this site were examined by Mary Dillon (Appendix 5). No charred seeds were recovered from the deposits. Poor retrieval is common in samples from burnt mound sites. 5.7 Charcoal Charcoal from this site was identified by Mary Dillon (Appendix 6). A total of six samples were examined and the remains were predominantly hazel followed in descending frequency by ash, alder and oak.

These included one burnt mound at Brackernagh, one at Perssepark and three at Doughiska. There is also a record of a possible burnt mound at Bredagh and a threatened site at Frenchfort that was not excavated as the development was changed to avoid the site. Archaeological inventories for the county list only six examples in west Galway, in- cluding one of the excavated examples at Doughiska (Gosling1993) and 17 in the north of the county (Alcock et al. 1999). The inventory for the south of the county is not yet published. Large scale archaeological works such as the N6 Galway to Ballinasloe road scheme (Con- tracts 1-4) demonstrate that these numbers are under-representative: this project involved the excavation of 12 burnt mound sites: at Doughiska, Furzypark, Clogharevaun, Killescragh, Newford, Caraun More, Barnacragh, Urraghry and Cooltymurraghy. The distance between the easternmost burnt mound at Barnacragh and the westernmost site at Doughiska was 47 km and the burnt mounds were spread across almost the entire length of the new road. However, they were concentrated within land covered by Contracts 2, 3 and 4, within areas of low-lying damp ground, a characteristic location for most burnt mound sites. Traditionally these sites have been interpreted as ancient cooking places, where large stones Permalink: http://eachtra.ie/index.php/journal/e2446-barnacragh-co-galway/ 7
    13. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 were heated in fires and then added to the water-filled trough, the extreme heat of the stones eventually heating the water in the trough until it reached boiling point. It could be main- tained at this heat by occasional additions of hot stones. Archaeologists suggest that meat was covered in straw or a similar wrapping and boiled within the trough. Experimental cooking at reconstructed sites such as Ballyvourney (O’Kelly 1954) has demonstrated that this could be achieved quite efficiently. However, the scarcity of animal remains from most excavated burnt mounds (although there are some exceptions) has left the question of function open to debate. Other theories on their use include bathing and dyeing textiles together with the pro- duction of hot water and steam for curative purposes and sweat houses (Ó Drisceoil 1988). All of these suggestions are speculative as there is virtually no conclusive scientific evidence to prove or disprove theories about how the sites were used. This may be partly because the sites that archaeologists describe as burnt mounds were used for several different purposes. We recognise the sites archaeologically by the remains of charcoal and heat shattered stones but as Ó Néill (2004) points out, these are the remains of a technology (the use of hot stones known as ‘pyrolithic technology’), rather than specific indications of the aim of the process. The radiocarbon date from Barnacragh fits in with the Early Bronze Age dates obtained from nearby burnt mound sites at Urraghry E2449 and Cooltymurraghy E2448. The concentra- tion of Early Bronze Age dates is interesting as most dated burnt mound sites have a focus of activity in the Middle to Late Bronze Age (Brindley & Lanting 1990; and see graph of dates in Ó Néill 2004). However, Early Bronze Age dates were returned from four of the nine burnt mound sites excavated along the route of the N25 Kilmacthomas realignment (Tierney in prep.) and a burnt mound sites at Doughiska, Co. Galway yielded a Late Neolithic/Early Bronze Age date (Fitzpatrick & Crumlish 2000). The three burnt mound sites at Urraghry, Barnacragh and Cooltymurraghy and other Bronze Age sites at Mackney E2445 and E2443 are found within an area where most of the known monuments date to the historic period (see Figure 3). The results from these sites provide a starting point for an exploration of Bronze Age settlement and landscape use in this part of East Galway. A probable Early Mesolithic stone tool was also found at this site. It was from topsoil and was clearly not associated with the archeology that was excavated at the site. However, it is a notable addition to the record of Mesolithic stone artefacts from the region and the first Permalink: http://eachtra.ie/index.php/journal/e2446-barnacragh-co-galway/ 8

Mesolithic finds were also found in secondary deposits excavated at Urraghry (E2449), c. 750 m to the west. The potential for Mesolithic activity in the area around Lough Corrib is discussed by Gibbon et al. (2004) and the finds from this site sug- gest that the area between the river Suck and the river Melehan was also exploited by hunter- gatherers. 7 Bibliography Alcock, O., de hOra, K. and Gosling, P. 1999 Archaeological Inventory of County Galway, Vol. 2 North Galway.

Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 10.3 Appendix 3: Groups and sub-groups text 10.3.1 Group 1 Burnt mound This group describes the deposits of burnt mound material, forming an elongated oval mound of charcoal-rich burnt and heat-shattered stone. Deposits of burnt stone C.5, C.66, C.89 Description: The oval mound of charcoal rich burnt and heat shattered stone was found to be homogenous throughout. The mound was composed of discarded heat shattered lime- stone, sandstone and quartzite. The condition of the discarded stone in the mound varied from very fragmentary and granular in character to larger, less fragmentary chunks and near complete water rolled and rounded stones. The main spread of charcoal and heat-shattered stone was C.5, which measures 5.8 m north to south by 2.35 m east to west. The mound was a maximum of 0.34 m in height. There was one find from the mound, a typical Bronze Age convex scraper. The typology of this artefact corresponds to the Bronze Age radiocarbon date that was obtained from this site. Spread C.66 measured 0.5 m in length, 0.46 m in width and 0.2 m in height and it was located 1.5 m to the east of the main mound of material C.5. A second spread, C.89, consisted of a sub-circular mound of charcoal rich burnt and heat shattered stone and was present in the eastern part of the excavated area. It measured 2.6 m in length, 2.4 m in width and 0.1 m in height and was located 2.5 m north of the trough (C.6). Both spreads are likely to have been a continuation of the main mound. Interpretation: The mound of burnt and heat shattered stone is essentially the discarded by-product or waste material of a technology which used hot stones to heat water. The size of the mound is an indication that many successive episodes of heating of stone took place. As no stratigraphic sequence was visible in the mound material it is thought that the mound was created through a continuous sequence of use. A glacially derived esker (a long, narrow ridge of coarse gravel deposited by a stream flowing in or under a decaying glacial ice sheet) located 35 m south of the burnt mound is thought to be the most likely source for the stones used in the heating process. The esker has been utilised as a quarry in recent times and large quantities of stone resembling the more intact examples from the mound were present close to the surface of the esker.

    40. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 10.3.2 Group 2 Trough This group describes the shallow sub circular trough found beneath the mound of stone. Cut C.6, Fills C.3, C.5, C.7, C.8 Description: The trough C.6 was composed of two elements; a shallow circular northern part and a lower southern linear part. Overall the trough measured 3.85 m NE to SW by 2.39 m NW to SE. The entire trough was situated beneath the mound of burnt shattered stone. The northern circular part which measured 2.39 m NW to SE by 2.2 m NE to SW and was 0.38m deep contained a number of stake-holes (See subgroup 1.3). The lower and southern part of the trough extended in a linear fashion for a distance of 1.8 m NE to SW and was 0.8 m in width and a maximum of 0.4 m deep. The trough was filled by four deposits (C.3, C.5, C.7 and C.8). C.3 was a deposit of peat that accumulated at the top of the trough after it was no long in use. The other three deposits were clayey silts that probably accumulated gradually after final use of the trough. Interpretation: The lower part of the trough may have functioned as an outlet channel when the heated water in the upper circular trough was being emptied. Where this the lower southern part or outlet channel met with the more circular northern part of the trough, a number of poorly preserved timber fragments were noted. It is felt that the northern circular part of the trough was used for retaining and heat- ing a volume of water. A circular superstructure may have been present here (See subgroup 1.3). Poorly preserved timber fragments were noted at the junction of the circular and linear components of the trough. It is thought that this represents the remains of a sluice mecha- nism for retaining and releasing water into the lower part of the trough. The lower part of the trough is thought to have functioned as an outflow channel to release water down slope towards the stream. During a period of heavy rainfall during the excavation the upper circular part of the trough was observed to be free draining with the lower possible outflow channel retaining water. 10.3.3 Group 3 Stake-holes A total of 12 stake-holes were located within the trough and 57 more were located under the mound and outside the trough in a linear arrangement extending to the west.

Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 10.3.3.1 Stake-holes within trough Cuts C.76, C.77, C.79, C.80, C.81, C.82, C.83, C.84, C.85, C.86, C.87, C.88, Fills C.91, C.92, C.145, C.146, C.147, C.148, C.149, C.150, C.151, C.152, C.153, C.154 Description: Twelve stake-holes were present within the trough, (C.76, C.77, C.79, C.80, C.81, C.82, C.83, C.84, C.85, C.86, C.87 and C.88). These were situated towards the sides of the trough. All stake-holes contained a similar dark grey sand silt fill. Two stake-holes situated in the west of the trough, C.84 and C.77, were deeper and wider than the other stake-holes present within the trough. They were situated on either side of the entrance to the linear projection which ran to the SW. The remainder of the stake-holes were present in an arc along the north and north- western side of the trough Interpretation: The stake-holes may have been used to support a wooden lining to the trough. They may also have been used to support wooden stakes onto which cloth or leather was fastened. The lining may have been composed of a wattle with clay or moss caulking. This type of structure would have allowed the hot stones to have been placed around the edges of the trough and heated the water inside the superstructure whilst keeping the hot stones outside. No evidence of clay or moss was uncovered. 10.3.3.2 Other stake-holes Cuts C.14, C.16, C.18, C.19, C.20-C.64, C.67, C.72-74, C.76, C57, C.159, Fills C.17, C.68, C.71, C.75, C.93-C.123, C.125- C.138, C.140-C.144, C.155, C.158 and C.160. Description: The 56 stake-holes, (C.14, C.16, C.18, C.19, C.20-64, C.67, C.70, C.72-74, C.76, C.156, C.157 and C.159) which represent this subgroup extend from the north-western edge of the trough for a distance of 5 m to the north-west. They contain similar fills and are all of a similar depth. The orientation of top to base displays some variation. This variation appears to correspond to a pattern. This pattern was observed to be that a centrally placed stake-hole had a stake-hole on either side. The central stake-hole was vertical with the stake- holes on either side angled towards the central stake-hole. Interpretation: It is thought that all of the stake-holes, in this subgroup, form part of the same structure or groups of structures. The stake-holes may represent the remains of a dry- ing rack or windbreak. The method of construction appears to be to support a load bearing linear structure. The arrangement was of vertical central stake-holes ‘buttressed’ by a stake- hole to either side. The load bearing capacity of this arrangement goes beyond the ordinary requirements of a windbreak. In addition to this, the work to create a windbreak using a woven hurdle work construction (rods and sails) technique would have been made difficult if not impossible by the presence of the angled stakes on either side of the central uprights.

Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 Although the structure may represent a windbreak it is it is more likely that these features represent the remains of a drying rack. 10.3.4 Group 4 Shallow circular Pit This group describes a shallow circular pit. Pit C.9, Fills C.10, C.11, C.12 Description: This was a shallow circular pit 1.31 m in diameter and a maximum of 0.13 m in depth. It was located 2 m to the NW of the NW-SE running linear arrangement of stake- holes (See subgroup 1.4). The pit contained three fills. The lower fill (C.10) was a red brown peat deposit. The middle fill (C.12) was a mid grey clay with no inclusions. The upper fill (C.11) was a dark grey black silt which contained occasional fragments of burnt stone. This cut of the shallow circular pit is very regular. Interpretation: The pit C.9 is thought to be a shallow lined pit. The function of this pit in unclear. The upper fill of the pit contains fragments of heat shattered stone, the lowest pit fill is very peaty in nature and may represent a lining of some kind.

Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 10.4 Appendix 4: Lithics By Dr. Farina Sternke, MA, PhD, Department of Archaeology, University College Cork 10.4.1 Introduction Two lithic finds from the archaeological investigations along the route of the N6 Galway- Ballinasloe Road at Barnacragh, Co. Galway, were presented for analysis. These are associated with the remains of a Bronze Age fulacht fiadh. 10.4.2 Methodology All lithic artefacts were examined visually and catalogued using Microsoft Excel. The follow- ing details were recorded for each artefact: context information, raw material type, artefact type, the presence of cortex, artefact condition, length, with and thickness measurements, fragmentation and the type of retouch (where applicable). The technological criteria recorded are based on the terminology and technology presented in Inizan et al. 1999. The general typological and morphological classifications are based on Woodman et al. 2006.

    44. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 10.4.5 Condition The lithics survive in patinated (E2446:1:1) and fresh (E2446:5:2) complete condition. 10.4.6 Technology/Morphology The artefacts represent a modified blade and flake. The blade (E2446:1:1) was most likely produced using a soft hammer stone, while the flake (E2446:5:2) is the result of a platform technology which used a soft to medium stone on a homogenous, fine-grained black chert. 10.4.7 Retouched Artefacts Both artefacts are retouched. Artefact (E2446:1:1) is retouched at its proximal and distal end as well as its left edge inverse at a low angle. This artefact resembles some known very slim examples of Neolithic leaf-shaped arrowheads (see Woodman et al. 2006, 130) and could represent a preform of the same. However, the fact that this blade does not show any bifacial retouch and would have been extremely slim when finished contradicts this identification. The well-developed patination and lustred surface suggest that is has been exposed to the ele- ments for a long time and might therefore be older. It is possible that it represents a slightly anomalous form of a rather broad Early Mesolithic needle point (see Woodman et al. 2006, 114). The type and location of the retouch would support this identification. The retouched chert flake (E2446:5:2) represent a very nice example of a typical convex end scraper. 10.4.8 Dating The retouched blade most likely dates to the Early Mesolithic based on its technology and typology, while the convex end scraper is not out of place in a Bronze Age context. 10.4.9 Conservation Lithics do not require specific conversation, but should be stored in a dry, stable environment. Preferably, each lithic should be bagged separately and contact with other lithics should be avoided, so as to prevent damage and breakage, in particular edge damage which could later be misinterpreted as retouch. Larger and heavier items are best kept in individual boxes to avoid crushing of smaller assemblage pieces. Permalink: http://eachtra.ie/index.php/journal/e2446-barnacragh-co-galway/ 39
    45. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 10.4.10 Discussion The lithic finds from the archaeological investigations at Barnacragh, Co. Galway, along the route of the N6 Galway-Ballinasloe Road are a possible Early Mesolithic needlepoint and chert convex end scraper. The latter is clearly associated with the Bronze Age fulacht fiadh, while the needlepoint which was recovered from the topsoil most likely represents a remnant of an Early Mesolithic presence in the area. Early Mesolithic settlement in the Midlands is well-represented through the excavated site at Lough Boora, Co. Offaly (Ryan 1978). Early Mesolithic material, albeit in secondary context, was also recovered 1km to the west at Ur- raghry, Co. Galway (Sternke 2006). 10.4.11 Recommendations for Illustration Retouched Blade (E2446:1:1) Scraper (E2446:5:2) 10.4.12 Bibliography Inizan, M.-L., M. Reduron-Ballinger, H. Roche and J. Tixier 1999.

Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 11.5 Appendix 5: Plant remains analysis By Mary Dillon 10.5.1 Introduction Eleven samples were submitted for plant remains analysis from the excavation of a burnt mound site at Barnacragh E2446, Co. Galway. 10.5.2 Methodology Bulk soil samples were collected on site and were processed post-excavation using a simple flotation method. Each sample was saturated in water to allow the carbonised plant material to float. This was then poured off into a series of sieves (1 mm and 250 µm), trapping the ‘flot’ (floating material), which was air-dried and stored in air-tight plastic bags. The flots were sort- ed and scanned for plant material and charcoal using a low-powered binocular microscope (magnification x 10 to x 40). Nomenclature and taxonomic orders follows Stace (1997). 10.5.3 Results None of the samples produced plant remains. 10.5.4 Discussion and Conclusion The lack of plants remains from this site is not altogether surprising. Burnt mounds and troughs, although commonly excavated, have yielded practically no plant remains (Penny Johnston, pers. comm.). 10.5.5 References Stace, C.A. 1997 New Flora in the British Isles (2nd edition), Cambridge, Cambridge University Press.

Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 10.6 Appendix 6: Charcoal analysis By Mary Dillon 10.6.1 Introduction Site E2446 is located in the townland of Barnacragh, Co. Galway. The site comprised a spread of burnt mound material, a trough, stake-holes and a pit. Charcoal from the site yielded an Early Bronze Age radiocarbon date. This report deals with the charcoal retrieved from the site and looks at the information produced on environment and selective use of wood types. 10.6.2 Methodology Bulk soil samples were collected on site and were processed post-excavation using a simple flotation method. Each sample was saturated in water to allow the carbonised plant material to float. This was then poured off into a series of sieves (1 mm and 250 µm), trapping the ‘flot’ (floating material). This was air-dried and stored in air-tight plastic bags. The flots were sort- ed and scanned for plant material and charcoal using a low-powered binocular microscope (magnification x 10 to x 40). All charcoal fragments of 2 mm or greater were identified. Each fragment was prepared for microscopic examination by fracturing it by hand and thereby exposing a clean surface along transverse, radial and tangential planes. All three planes were examined at a range of magnifications (x 5 to x 100) under a Nikon stereo microscope. For reference literature the website ‘wood anatomy’ was consulted. The number and weight of fragments were recorded for each charcoal type. 10.6.3 Results In all, 168 charcoal fragments were identified from six samples. In Figs 1 and 2 percentage frequencies of the various charcoal types based on fragment count and dry weight, respectively, are shown. The most frequent charcoal type overall is hazel at 49% or 46% by weight. This is followed in descending frequency by ash 33% / 28%, alder 15% / 24% and oak 3% / 2%. When considered on a weight basis the results change slightly (Fig. 2). Permalink: http://eachtra.ie/index.php/journal/e2446-barnacragh-co-galway/ 42
    48. E2446 | A024/33 Barnacragh, Co. Galway ISSUE 2: Eachtra Journal - ISSN 2009-2237 10.6.4 Discussion Burnt mounds are a common feature of the Irish landscape. Charcoal analysis from burnt mounds excavated along the Gas Pipeline to the West demonstrates that a range of trees were gathered as firewood, particularly alder (Alnus glutinosa), hazel (Corylus avellana), oak (Quercus spp.) and ash (Fraxinus excelsior) (O’Donnell 2005). O’Donnell’s studies imply that the same wood types were used as fuel in burnt mounds across the country, which suggests that a selection process of some kind was in place. These trees were also common at Kiltotan Colinstown burnt mound in Co. Westmeath (Dillon 2006) and nearby burnt mound sites at Cooltymurraghy E2448 and Urraghy E2449 (Dillon 2007a, 2007b). The assemblage from Barnacragh was a typical burnt mound assemblage, although hazel dominated to the detri- ment of oak. This is in slight contrast to the nearby burnt mound at Urraghry where all wood types were equally represented. Hazel was the most common wood type in the Barnacragh assemblage. It was widely exploit- ed in both prehistory and historical times for its nutritious nuts and supple rods which were widely used for building. Its coppice-like growth form makes it relatively easy to cut and there are normally substantial quantities of dead wood available near ground level for fuel wood. A pollen diagram from Mongon Bog, near Clonmacnoise in Co. Offaly, (Parkes & Mitchell, 2000) indicates that during the Bronze Age hazel was one of the most prominent trees. Ash was the second most common wood type. It makes great fuel, burned green or dead, and this may have influenced its selection. According to the pollen diagram it was readily avail- able in the locality. Alder was the third most common wood type. Alder is quite common in the Parkes & Mitchell diagram (2000), but was probably largely confined to damp/wet areas. Given that burnt mounds are often suggested as places where dyeing may have been carried out (Waddell 1998, 177), it is interesting to note that alder bark and catkins were used to make a black dye in the past. This could be a reason for the abundance of alder wood that is associated, not just with this particular site, but with burnt mounds countrywide Oak made up just a small percentage of the assemblage. It is slow burning and gives out sub- stantial heat as it burns which would have made it a natural choice for a fire. Permalink: http://eachtra.ie/index.php/journal/e2446-barnacragh-co-galway/ 43
