The earliest writing on Cyprus dates to about 1550 BC and continued in use for about 500 years. It is called Cypro-Minoan because the signs resemble the "Linear A" script of Minoan Crete. Cypro-Minoan was used throughout Cyprus, in the Syrian port city of Ugarit, and on thousands of pottery vessels found across the Mediterranean. A unique blend of linear Aegean and Near Eastern cuneiform (wedge-shaped) writing styles, it became the business language of merchants traveling by sea. Modern scholars have not yet deciphered it.
