The 6 Greatest Unsolved Mysteries We May Never Figure Out

No. 5 Phaistos Disc

The story of the Phaistos Disc is one of the most famous riddles of archaeology. This disc was discovered by an Italian archaeologist called Luigi Pernier, in 1908, during an expedition to the Minoan site of Phaistos. The disc is made of fired clay, and is engraved with very particular symbols, which are thought to be some strange and unknown form of hieroglyphics. Despite the numerous attempts from archaeologists, scientists and historians to crack the code, this disc’s origin hasn’t been figured out. It is thought to be from some time in the second millennium BC, and the hieroglyphs apparently resemble symbols of Linear A and Linear B, which are originally from ancient Crete. Nevertheless, the Linear A symbols haven’t been deciphered yet either.
