Linear A
Undeciphered writing system of ancient Crete
Linear A is a writing system that was used by the Minoans of Crete from 1800 BC to 1450 BC. Linear A was the primary script used in palace and religious writings of the Minoan civilization. It was adapted into Linear B, which was used by the Mycenaeans to write an early form of Greek. Since its modern rediscovery in 1900, no texts in the script have yet been deciphered.
