Linear A
Linear A is a writing system that was used by the Minoans (Cretans) from 1800 to 1450 BC to write the hypothesized Minoan language. Linear A was the primary script used in palace and religious writings of the Minoan civilization. It was discovered by archaeologist Sir Arthur Evans. It was succeeded by Linear B, which was used by the Mycenaeans to write an early form of Greek. No texts in Linear A have been deciphered.
