Definition: The word "Antikythera" is a Greek term that refers to an ancient device used in Babylonian timepieces for astronomical calculations, particularly the Babillean Calendar, but also by other cultures around the world. - The Antikythera mechanism was developed in the 6th century BCE and used a system of hand movements, known as the "cyclopidium," to calculate cycles. This method was not accurate enough for astronomical calculations. - However, it is believed that the device was used by Babylonians or other pre-Babylonian peoples to aid with navigation, weather forecasting, and date determination. The term Antikythera itself comes from the Greek word "antik," which means "against" in Ancient Greek. The name was originally given to a device used to measure time, but later it became associated with astronomical calculations, particularly those related to Babylonian calendars.
