Earliest known writing in the European/Mediterranean zone. 

The earliest known writing system in the European/Mediterranean zone is the Cretan Hieroglyphic script from ancient Crete, part of the Minoan civilization. This script dates back to around 1900 BC to 1700 BC. Closely related and slightly later in development is Linear A, which emerged around 1800 BC and was also used by the Minoans.

These scripts were used primarily on the island of Crete and remain largely undeciphered, making it difficult to fully understand their content and purpose. Linear A, in particular, appears to have been used for administrative and religious purposes. Following these, the Mycenaean civilization developed Linear B, derived from Linear A, which has been deciphered as an early form of Greek and dates back to around 1450 BC. Linear B provides substantial insights into the administrative, economic, and daily activities of the Mycenaean Greeks.
