Crete. Archaeologists working at a Minoan site discovered a circular clay disk covered in spiral script, with 241 very elaborate signs or letters, evidently printed on the clay. The meaning of these signs remains a mystery, as nothing else of the same type has been found since. Furthermore, dating to 1700 BC, it is by far the earliest printed document in human history. Probably 45 different stamps (types) were used. It is called the Phaistos Disk.
