Eberhard of Béthune was a Flemish grammarian of the early thirteenth century, from Arras. He was the author of Graecismus, a popular Latin grammatical poem, dated to c. 1212. The name came from a short section on the Greek language. His Laborintus is "an elaborate and critical treatise on poetry and pedagogics"; it is also known as De Miseriis Rectorum Scholarum.
