Silver ring, "The Phaistos Disc" with trident on the sides (medium)

The Phaistos Disc is an archaeological find found in the homonymous city of Phaistos, on the island of Crete, under a wall of a Minoan palace. Its purpose and significance, as well as its original geographical location of the manufactory, are still debated, making it one of the most famous mysteries of archeology. The disc is covered with symbols not engraved but imprinted with molds when the clay was still fresh, arranged in a spiral on both sides, in a clockwise sequence that goes towards the center. The total symbols are 242, and are divided into small groups by thin lines. The writing was done with great attention to detail, in order to close the spiral exactly in the center and to occupy all the available space. The most accredited interpretation is that it is a form of syllabic writing, also because the high number of distinct symbols (45) seems to exclude the possibility that these are alphabetic signs. In any case, the signs of the disc have remained undeciphered, and reveal no formal resemblance to those of any other known writing.
