Johannes Vahlen

Johannes Vahlen (27 September 1830 in Bonn – 30 November 1911 in Berlin) was a German classical philologist.

[1] From 1874 onward, he taught classes as a professor of classical philology at the University of Berlin.

Vahlen was a specialist of Greek and Latin literature, publishing works on a wide array of ancient authors that included Aristotle, Ennius, Horace, Plautus and Gnaeus Naevius.

He is particularly known for his interpretive work involving the Poetics of Aristotle and the fragmentary relics of the poet Ennius; Ennianae poesis reliquiae.

In 1913 Vahlen's library of over 10,000 volumes of ancient and classical works was acquired by the University of Illinois.
