Eberhard of Béthune (also known as Everard of Béthune, Évrard de Béthune, Éverard de Béthune, Ebrardus BethuniensisorBithuniensis, Eberhardus Bethuniensis, Eberard, Ebrard, Ebrad; died c. 1212)[1] was a Flemish[2] grammarian of the early thirteenth century, from Arras. He was the author of Graecismus, a popular Latin grammatical poem, dated to c. 1212.[3] The name came from a short section on the Greek language.[4] His Laborintus is "an elaborate and critical treatise on poetry and pedagogics";[5] it is also known as De Miseriis Rectorum Scholarum.
He was also actively engaged against the Waldensians,[6] and wrote a book entitled Liber Antihaeresis (c. 1210) against them. He is cited in Foxe's Book of Martyrs as to the etymology of the name.[7]

Its name, Graecismus, was based upon a chapter, the eighth, devoted to the elementary study of Greek.
