The Antikythera mechanism, a remarkable ancient calculator, has intrigued researchers since its recovery in 1901. A recent study in The Horological Journal suggests that the device's calendar ring may have contained 354 holes, contradicting previous assumptions of a 365-day solar calendar. The study, drawing on methods from gravitational wave astronomy, challenges established beliefs about the mechanism's design. While some experts remain skeptical, the findings highlight the ongoing fascination and mystery surrounding the Antikythera mechanism, emphasizing its dynamic nature and potential for continued discovery.
