medieval poet and wandering scholar, a pupil of Peter Abelard and associated with Angers, Anjou.

Hilarius wrote light verse of great charm in Latin, including poems dedicated to English persons—which has led to the otherwise unsupported theory that he was English himself. His fame rests on three Latin religious plays, two of which, like two of his poems, have French refrains. Those on the raising of Lazarus and on Daniel were written to be performed at matins or vespers. Both follow the biblical narrative fairly closely. The third play, which bears no trace of liturgical performance, is on a nonbiblical subject: the legend of the image of St. Nicholas. All three plays show variety of metre, great liveliness and dramatic power. The French refrains (lacking in the play on Daniel), which are a lyrical addition, not an interpretation of the Latin, give an impression of directness and freshness.
