Linear B is an ancient script used by the Mycenaean civilization in Greece around 1450 to 1200 BCE. It is primarily found on clay tablets and was used for administrative and economic purposes, recording information about goods, resources, and transactions. The script is a syllabic writing system, meaning it represents sounds rather than individual letters. Linear B was deciphered in the 1950s by Michael Ventris, revealing insights into the language and culture of the Mycenaean people, as well as their connections to later Greek civilization.
