German philologist, poet, and commentator on Virgil. He was one of the last of the Renaissance humanists.

Frischlin was educated at the University of Tübingen, where he became (1568) professor of poetry and history. In 1575, for his comedy Rebecca, which he read at Regensburg before the Holy Roman emperor Maximilian II, he was rewarded with the laureateship, and in 1577 he was made a count palatine.

In 1582 Frischlin had to leave Tübingen, and he spent two years teaching at Laibach. Shortly after his return to Tübingen in 1585, he was threatened with a criminal prosecution for immoral conduct and fled to Frankfurt am Main (1587). For 18 months he taught in Brunswick, and he appears also to have lived at Strasbourg, Marburg, and Mainz. From Mainz he wrote libelous letters, which led to his arrest in March 1590. He was imprisoned in the fortress of Hohenurach, where, on the night of Nov. 29–30, 1590, he was killed in a fall while attempting to let himself down from the window of his cell.

In his Latin verse Frischlin often successfully imitated classical models. His Latin comedies have freshness and vivacity, and his commentaries on Virgil's Georgics and Bucolics were important contributions to the scholarship of his time. He also wrote plays in German.
