Introduction:
-Definition of re-employment:
Re-employment is one of the characteristics of Ifrîqiyan architecture, heir to
Byzantine architecture, which gave a large place to this practice. In the
Middle Ages, as in modern times, abandoned sites and ruined monuments
were used extensively in the construction of the most beautiful buildings in
the country, particularly mosques1.
-Another definition:
"Implementation, in a construction, of elements, materials from a previous
construction." 2
Summarizing the two definitions, we can define it like this: using an
architectural element that dates from a previous era and incorporating it into
another building from another era

Info N ° 31, May 2015
The Great Mosque occupies the
heart of the medina of Tunis
governorate of Tunis, it is the
core around which the city has
developed
`
History of the Mosque:
Zaitouna which means the olive tree built in 248/864 AD by the architect Fethullah
according to an inscription on the base of the dome of the mihrab, under the Aghlabid
emir Abu Ibrahim Ahmed and the Abbasid caliph al Moustaïn Billah on the remains of 'a
Christian basilica
The mosque has seen several interventions since its foundation, as all governments
have left their mark
We note here the most important dates in the construction of the mosque:
- 990: the construction of the dome above the entrance by Zirid Governor Al-Mansour
- 1637: The construction of the eastern gallery which overlooks the souk
- 1896: reconstruction of another higher minaret (43m)
- After the independence of Tunisia, the mosque underwent several restoration works 3

Problematic:
The Zaitouna mosque, one of the oldest mosques in Tunisia, unique by its architecture
and by the variety of these reused antique capitals
What is the origin of these capitals?
What are the types of capitals in the mosque?
to answer this problematic, we have based ourselves on several documents, reviews
and websites:
- firstly on our site visit which took place on 08/17/2016
- the book: Reuse in Ifrîqiyenne mosques in medieval times
and modern by Ahmed Saadaoui
- The book: Note on the domes of the great Al-Zaytuna mosque in Tunis
By Lucien Golvin
- Cadran Info magazine N ° 31
- The website of the municipality of Tunis
- The site www.Persée.com
- The net site: www.Tunisiens de France.com
- The net site: www.Discoverislamicart.org
- Personal efforts (photo, movement, interpretation)
`
Introduction:
The Tunisian religious heritage presents a variety of architectural styles corresponding
to the different civilizations present on its territory from the earliest times of its
Islamization to the present day. Our interest focused on researching the capitals of the
Zaitouna mosque and their origins

- Spatial study of the mosque:
The Zaitouna mosque is composed of two architectural spaces:
1-a prayer room, covers an area of 1344 m², composed of 15 naves and 7 bays, with a
skeleton ceiling which occupies almost the southern half of the building and which in
addition to two cupolas: the 1st above the mihrab the 2nd on the above the entrance;
this space is set on arches and columns4
4
2- a trapezoidal courtyard, surrounded by an arcade gallery There are also other
components such as the minaret (3) located in the North West corner, and the ablution
room (4), in the basement.

Originality of the capitals:
The Zaitouna Mosque has more than 160 columns and capitals some are from the
ancient period, and some from the Islamic period5
, but what is evident that this ancient
material comes from the ruins of Carthage6
.
A-Courtyard capitals:
The courtyard is surrounded by 4 arcade galleries including: The narthex gallery:
Located to the north west of the courtyard, it rests on 22 Antique7
7 columns and
capitals, surmounted by a dome supported by 6 columns, which marks the entrance to
the prayer room

the capitals of this gallery vary between Corinthian, composite, ionic, but we can clearly
see that their state of conservation is average, and they have somewhat disfigured

Analysis: one notices that the 2 capitals on the right are higher than the one on the left The presence of
2 white marble blocks of different typology that connects the columns with the arch We also notice the
red color of the column in the middle while its capital is white
The capitals of the other three galleries:
North West, North East and North gallery.
These are composite capitals in white marble imported from Italy, this operation is carried out under
Minister Khaznaar in the middle of the 19th century8

Dimensions: height: 0.5 m; laying bed: circular, D = 30 cm. Condition: Generally in good
condition
Analysis:
- We notice that the arc begins just after the capital, and this is the normal case, as we
said before that these columns were imported from Italy to measure

northwest gallery (framed in Fig. 16)

`
B- Capitals of the prayer room:
-The capitals of the prayer room are reused (from antiquity)
-The 4 capitals of the mihrab are from the Islamic period, made of white marble, they
are based on 4 cylindrical barrels on the other hand the barrels from the ancient period
are curved (5).
in this study will take 3 type capitals which represent practically all the capitals of the prayer room and
study them.
1- big top B7, 2- big top D1, 3- big top G7.

-Description of Capital B7 :
It is a typical capital which represents the capitals of the central nave, (A7, C7, D7, E7,
F7, G7) and (A8, B8, C8, D8, E7, F8, G8)
Fig. 29 Capital B7

`
- Data
Material: marble Dimensions: high. : 0.4 m; laying bed: circular base 0.3 m in diameter.
Condition: Broken angles, several breaks on the abacus and astragalus; the carved
decoration
Analysis:
- We notice that the arc does not start from the capital, but after 3 blocks of different
dimensions - Block number 1 is 8-11 cm high - The block num. 2 is 45-50cm tall - The
block num. 3 is 7-10cm tall - The color of the column is red, the capital, white - We also
notice that the materials of these blocks are different - From this analysis we can say
that the column is not authentic because its height and the height of the beginning of
the arc are different, so the capital is also reused.
- Description of Capital D 5:
Fig. 37 the capital D5, Source : pp Fig.32 vue de face du chapiteau D5, Source : pe
`
Data:
Dimensions: high. : 0.3 m; laying bed: circular, D = 30 cm.
Conservation state :
Generally in good condition
- Analysis:
This capital resembles the capitals À, B, C, D, E, F (1-5) -We note that the arc of the
gallery rests on a rectangular base element which is enlarged, 60-70 cm in height. height
- the color of the column and the capital is the same - the block that connects the
column and the arch is designed by a different material than the rest of the column
our hypothesis is that the column is not authentic so the capital is also reused
Description of Capital F9:
Fig. 33 double columns under an arch, Source: pp
`
Fig. 34 front view of the double column F9, Source: pe
Data:
Dimensions: high: 0.4 m; laying bed: circular, D = 30 cm. X 2
Conservation state:
Generally, in good condition
- Analysis:
This capital also represents the double capital F (8, 9, 10,11,12,13,14)) We notice that
the arc of the gallery rests on a rectangular base element but larger than that of the
capital D5, 60-70 cm high, we can have made this block especially so that the column
can join the arch The block that connects the column is specific for this whole gallery (F)
- The order of these capitals is Corinthian
- The material used in the column and the block is different
- We also notice that the two capitals are not 100% alike
- The result is the same: difference in materials, color and type means difference in
construction period
`
- Conclusion :
From the analyzes and the study that we have done on these three capitals with the
help of historical documents, articles and reviews, we can come to the following
conclusion: - The capitals of the Zaitouna mosque are divided into 2 parts:
- 1- capitals imported from abroad to measure: and inserted directly, and this is the
case of the columns and capitals of the three galleries of the courtyard (north, north-
east, west)
- 2 the re-used columns and capitals: this is the case of the capitals and columns of the
narthex gallery and those of the prayer room, we were able to identify the criteria on
which we based to say that these re-use:
1-The homogeneity of capitals and columns in an architectural space
2- the homogeneity of the materials used
3- the homogeneity of the typology of columns and capitals
4- the homogeneity of the orders of the capitals
If one of its criteria is missing in an architectural space, we can say that one or more
elements have been used

  • 5. ` Introduction: -Definition of re-employment: Re-employment is one of the characteristics of Ifrîqiyan architecture, heir to Byzantine architecture, which gave a large place to this practice. In the Middle Ages, as in modern times, abandoned sites and ruined monuments were used extensively in the construction of the most beautiful buildings in the country, particularly mosques1. -Another definition: "Implementation, in a construction, of elements, materials from a previous construction." 2 Summarizing the two definitions, we can define it like this: using an architectural element that dates from a previous era and incorporating it into another building from another era 1 -Saadaoui, Ahmed The re-employment in Ifrîqiyenne mosques in medieval and modern times, CNRS ÉDITIONS, Paris, 2008 2 -French dictionary Larousse, site: http://www.larousse.fr

  • 25. ` - Conclusion : From the analyzes and the study that we have done on these three capitals with the help of historical documents, articles and reviews, we can come to the following conclusion: - The capitals of the Zaitouna mosque are divided into 2 parts: - 1- capitals imported from abroad to measure: and inserted directly, and this is the case of the columns and capitals of the three galleries of the courtyard (north, north- east, west) - 2 the re-used columns and capitals: this is the case of the capitals and columns of the narthex gallery and those of the prayer room, we were able to identify the criteria on which we based to say that these re-use: 1-The homogeneity of capitals and columns in an architectural space 2- the homogeneity of the materials used 3- the homogeneity of the typology of columns and capitals 4- the homogeneity of the orders of the capitals If one of its criteria is missing in an architectural space, we can say that one or more elements have been used Fig. 35 marking plan of the capitals reused and not, Source: pe
