The Phaistos Disc is a mysterious clay disc, about 3400-3850 years old, discovered in the basement of a Minoan palace. It is imprinted with hieroglyphic symbols. It is the earliest known instance of movable-type printing, which would not be seen again until woodblock printing appeared in China some 1600+ years later.
For some reason, Wikipedia's pages on Greek mythology are very often vandalized.
