Ancient scripts of Linear A and Linear B were found on the island of Crete and on the Greek mainland. Linear A was used by the Minoan civilization on Crete between 1800 BCE and 1450 BCE, while Linear B was used by the Mycenaean civilization on the Greek mainland between 1450 BCE and 1200 BCE. Linear A has not yet been deciphered, but Linear B has been found to be an early form of Greek.
