The Phaistos Disk. Clay disk found at the Palace of Phaistos. On both sides 242 signs have been impressed with sealstones, running in a spiral form starting from the edge towards the centre. The signs belong to an ideographic and probably syllabic script, which has not yet been deciphered despite the numerous attempts over the years. The exact date of the disk is also questionable, but it probably dates from the MM IIB period (17th century B.C.). Inv. no. EP 1358.
