ANCIENT GREEK INNOVATIONS
1st Experimental Lyceum of Thessaloniki “Manolis Andronikos”
THE FLYING PIGEON OF ARCHYTAS
 The flying pigeon of Archytas (4th century b.C.)
was the first flying machine in human history.
HYDRAULIC TELEGRAPH
 It was constructed
by Aeneas Tacticus
(about 40 B.C.).
 It was used for the
rapid transfer of
messages within
the large Empire of
Alexander the
Great.
 Containers filled with water were
put on separate hills.
 Rods inscribed with various
predetermined codes (same for
both rods) floated within the
containers at various points along
their height.
 To send a message the sending
and the receiving operators
opened simultaneously the spigots
at the bottom of the containers.
 While the water was draining out, the rods
was sinking inside the containers.
 When the water level reached the desired
code, the sending operator would make a
signal to the receiving operator to close the
spigot.
 The receiving operator would then read the
code inscribed at that height of the rod –
which was the message that the operator
from the other hill wanted to send him.
AUTOMATIC DOORS OPENING
 Hero of Alexandreia constructed a mechanism
for the automatic opening of the doors, which is
based on the properties of air and liquids
(about 100 B.C).
 This mechanism is supposed to have been
used in the temple of Diana in Ephesus.
 The air from a closed
chamber heated by
the altar fire was
used to displace
water from a sealed
vessel. The water was
collected and its
weight, pulling on a
rope, opened the
temple doors.
HERO ENGINE
 An aeolipile (aelosphere),
also known as a Hero
engine, is a simple
bladeless radial steam
turbine which spins when
the central water
container is heated.
Torque is produced by
steam jets exiting the
turbine, much like a tip
jet or rocket engine.
HYDRAULIS
The first keyboard musical
instrument, the Hydraulis
was invented by Ctesibius
of Alexandria in the 3rd
Century B.C. Hydraulis is
the ancestor of the modern
church organ.
A modern reconstruction of
the ancient hydraulis.
HYDRAULIC AUTOMATON OF THE «CHIRPING
BIRDS» AND OF THE «RETURNING OWL»
The hydraulic automaton of
the «chirping birds» and of
the «returning owl»
was an exceptional
automatism of repeating
spectacle with motion and
sound production.
ANTIKYTHERA MECHANISM
 The Antikythera
mechanism (2nd century
b.C.) was found in 1900–
1901 in the Antikythera
wreck. Τhe mechanism
was an analog computer
designed to calculate
astronomical positions
and was used to predict
lunar and solar eclipses
based on Babylonian
arithmetic-progression
cycles.
