Linear A Script Tablet Recreation (about 4 1/4 by 3 1/4 inches, resin cast). From 13th to 14th century BC. Linear A is one of two scripts used in ancient Crete before Mycenaean Greek Linear B; Cretan hieroglypic is the second script. In Minoan times, before the Mycenaean Greek dominion, Linear A was the official script for the palaces and religious activities, and hieroglyphs were mainly used on seals. These three scripts were discovered and named by Arthur Evans. In 1952, Michael Ventris discovered that Linear B was being used to write the early form of Greek known as Mycenaean. He and others used this information to achieve a significant and now well-accepted decipherment of Linear B, although many points remain to be clarified. By contrast, Linear A has not been deciphered since the language of Linear A has not been discovered (Wikipedia).
