The lyre (Greek: λύρα, lýra) is a string instrument known for its use in Greek classical antiquity and later periods. The lyre is similar in appearance to a small harp but with distinct differences. The word comes via Latin from the Greek; the earliest reference to the word is the Mycenaean Greek ru-ra-ta-e, meaning "lyrists" and written in the Linear B script. The lyres of Ur, excavated in ancient Mesopotamia (modern Iraq), date to 2500 BC.
