Ars Amatoria
The subject matter is often sexual: fabliaux are concerned with the elements of love left out by poets who wrote in the more elevated genres such as Ovid, who suggests in the "Ars Amatoria" (II.704–5) that the Muse should not enter the room where the lovers are in bed; and Chrétien de Troyes, who maintains silence on the exact nature of the joy discovered by Lancelot and Guinevere in "Le Chevalier de la Charrette" (4676–4684). "Lais" and fabliaux have much in common; an example of a poem straddling the fence between the two genres is "Lecheor".
