Linear B is a fascinating writing system that was used to write the Mycenaean Greek language. We don't know exactly how old it is, but it seems to have developed about 3,500 years ago. Scholars named it called Linear B because there's also an older version of it, which they call Linear A. Linguists still can't figure out how to read Linear A, and it's one of the great mysteries of classical studies.
