An acrylic model made in 1981 of what is believed to be one of the earliest geared mechanical calendar device. The model was based on drawings made by Dr. Derek de Solla Price during his study of bronze fragments in the early 1970's. The few original fragments were found in the Aegean Sea in 1900 with other material from a shipwreck near the island of Antikythera. The device is believed to have been made c. 87 BC, possibly by a mechanician from the Rhodes school of Polonius. Research into the object continues today. Donated to the Museum by Dr. Derek de Solla Price & Mr. Russell W. Elwell.
