Eberhard of Béthune

Eberhard of Béthune (died ) was a Flemish grammarian of the early thirteenth century, from Arras. He was the author of Graecismus, a popular Latin grammatical poem, dated to around 1212. The title derives from a short section on the Greek language.

Eberhard was also actively engaged in opposing the Waldensians and wrote a book entitled Liber Antihaeresis (c. 1210) against them. He is cited in Martyrs Mirror and Foxe's Book of Martyrs in relation to the etymology of the movement's name.
