The Bank of Greece announces the issuance for next September 13 of a collector's coin with a face of 10 euros in silver dedicated to the Antikythera Mechanism, an ancient mechanical calculator designed to predict the position of the Sun, the Moon, and some planets, which allowed to predict eclipses. This will be the first coin in a series called “Ancient Greek Technology”.

The Antikythera Mechanism was recovered in the Aegean Sea between 1900 and 1901 from an ancient shipwreck near the Greek island of Antikythera. Built in Hellenistic times, this intricate device was used for astronomical calculations and has been described as the oldest analog computer.

Its more than 30 bronze toothed wheels turned pointers on different spheres. Thus, manually selecting a date on the main dial, which represented the zodiac as well as solar and lunar years, moved the smaller gears so that the pointers on the other dials indicated the position of the selected date on the dial. four-year cycle of the Panhellenic games (Olympia, Pythia, Isthmia, Nemea), the positions of the five planets then known and the correlation with the astronomical cycles that especially interested the ancient Greeks. The mechanism also predicted solar and lunar eclipses.

Research into the mechanism, which has fascinated scholars for decades, continues under the Antikythera Mechanism Research Project, which, through the use of advanced imaging technologies, continues to provide impressive new insights into the complex. internal workings of the mechanism. 

The coin shows as a central motif a part of the Antikythera Mechanism that can currently be seen in the National Archaeological Museum in Athens. In the semicircle that surrounds it appear the inscriptions «ΑΡΧΑΙΑ ΕΛΛΗΝΙΚΗ ΤΕΧΝΟΛΟΓΙΑ – Ο ΜΗΧΑΝΙΣΜΟΣ ΤΩΝ ΑΝΤΙΚΥΘΗΡΩΝ» (Ancient Greek Technology). The year of issue 2022 is shown on the left hand side, and the mint mark on the bottom right of the mechanism.

The reverse, common to the entire series, shows in the foreground, on a background of integrated circuits, the coat of arms of Greece surrounded by the text “ΕΛΛΗΝΙΚΉ ΔΗΜΟΚΡΑΤΊΑ” (Hellenic Republic) and the face value 10 EYPΩ (10 Euro).

The coin is presented as you can see below these lines. The selling price of this coin in Greece is €80.
