The Phaistos Disc is a disk of clay from the Minoan palace of Phaistos on the island of Crete, possibly dating to the middle or late Minoan Bronze Age. The disk is about 15 cm (5.9 in) in diameter and covered on both sides with a spiral of stamped symbols.

The disc was discovered in 1908 by the Italian archaeologist Luigi Pernier, it features 241 tokens, comprising 45 distinct signs, which were apparently made by pressing hieroglyphic "seals" into a disc of soft clay, in a clockwise sequence spiralling toward the center of the disk.

The Phaistos Disc is generally accepted as authentic by archaeologists.The assumption of authenticity is based on the excavation records by Luigi Pernier. This assumption is supported by the later discovery of the Arkalochori Axe with similar, though not identical, glyphs.
