Ancient mechanics
Antikythera and Archimedes
The Antikythera Mechanism is the material proof that, in the ancient world, the motion of the sky was translated into gears. Tradition connects it to a line of makers that passes through Archimedes and Syracuse.
Themes
- The Antikythera Mechanism: structure, functions and state of the reconstruction.
- Archimedes and the tradition of planetaria.
- Phidias — the astronomer named in the sources as the father of Archimedes.
- Ancient planetaria as instruments of calculation and of representation.
- The calendar and the cycles the mechanism incorporates.
- The Syracusan scientific tradition.
Encounters and scientific exchange
Work on Antikythera proceeds through direct exchange with those who study the mechanism and ancient astronomy. The people listed here are interlocutors met at SEAC XXXIII in Volos, in September 2026: their presence in these photographs documents a meeting, not an endorsement of the project.
University of Athens
Xenophon Moussas
Astronomer, professor of space physics, among the leading figures in the study of the Antikythera Mechanism. Former director of the Astrophysics Laboratory and of the Observatory of the University of Athens, and deputy head of the Physics Department. Member of the International Astronomical Union.
Uppsala University
Göran Henriksson
Astronomer, PhD at Uppsala in 1983. Developed a program for the accurate computation of ancient solar eclipses back to 4000 BC. In 2009 he identified ten solar eclipses on the Antikythera Mechanism and proposed its calibration at Syracuse.
