Here is a question about this article: Matches are held within a wrestling ring, an elevated square canvas mat with posts on each corner. A cloth apron hangs over the edges of the ring. Three horizontal ropes or cables surround the ring, suspended with turnbuckles which are connected to the posts.

Here is a question about this article: The Antikythera mechanism is believed to be the earliest mechanical analog "computer", according to Derek J. de Solla Price. It was designed to calculate astronomical positions. It was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to circa 100 BC. Devices of a level of complexity comparable to that of the Antikythera mechanism would not reappear until a thousand years later.
