Complex clock combines calendars

Antikythera Mechanism may have timetabled ancient Olympic Games.

The Antikythera Mechanism, a clockwork device made in Greece around 150–100 BC, astounded the world two years ago when scientists deduced how this machine was used to make complex astronomical time-reckonings. Now they say that the instrument, discovered in 1901 in a Mediterranean shipwreck, did much more than that.

  • Very interesting! Greek history and mythology are a big interest of mine. I was just curious if this device has been mentioned in any greek historical, scientific, or even social/cultural texts?

  • There is a very interesting web application that lets you interactively relight and change the surface materials of the Antikythera so that you can see more detail in the photo http://www.hpl.hp.com/research/ptm/antikythera_mechanism/index.html

  • It's astounding the methods used by modern scientists to discover details of the past of humanity, and not only the revealing of the very past. But the discovered mechanism is really incredible for the established date of its fabrication. Great matter and video.

  • I have been watching the research on this artifact for the last few years and would like to commend the great work all have done in this task. My field of research is Ancient tools for navigation and I see a connection with this tool to many I have researched. When the final translation of this tool is completed I feel you will understand how the ancients used the moon,s position in it's 18.6 year cycle to determine longitude location. Simular tools were used in North America (Liahona), South America (Coba Dial), New Gunie (New Guine Dial). This method is also present in an ancient Load Stone compass I am researching from Spain found in America. Serious researchers may contact me at (wmsmithrock1@yahoo.com)
