Silver Bookmark with  Festos/Phestos Disc Coin
 

Sterling silver  bookmark decorated with Festos/Phestos Disc.

The disc of Phaistos is classified by many as one of the most mysterious objects of all time.
The original artifact is a stone carving that can be seen in the Heraklion museum in Crete. It's size fits into a palm of a large male hand, it has captivated the mind and imagination of an unprecedented amount of researchers and remains an unsolved mystery.
The disc is considered particularly important as it was one of the very few valuable objects found in the very heart of the mighty Minoan civilization from just before it's overnight destruction from a tidal wave (linked to the loss of Atlantis). When the palace was excavated, in crypt beneath the floor of  Royal chamber of the palace of Festos was this disc, hidden from the public domain.
Some of the characters or 'glyphs' have been compared to Linear A and some resemble Egyptian hieroglyphs but apart from this resemblance the origin of the language is uncertain and incomparable to other known scripts.
Over the twentieth century there has been an endless list of archaeologists, linguists, anthropologists and even astronomers all of which have provided their own theorems for the disco's interpretation or intended function. Among the most interesting are the explanation of the disc being a very advanced form of ancient calendar, or a cosmic map in which elements inside the carved spiral mark the position of stars in our galaxy. Other theories link this artifact and language to the lost city of Atlantis.
