French writer, author of plays, poems, stories, songs and epigrams. He wrote tragedies and comedies, as well as numerous comic operas. His Ode à Priape (Ode to Priapus) was used as a pretext to refuse him entry to the Académie française.

He was the author of two plays for puppets, Le Mariage de Momus ou la Gigantomachie (1722) and Colombine Nitétis (1723). Puppets also appeared in two of his plays for actors: Polichinelle in Arlequin-Deucalion (1722) and a large body puppet in L'Endriague (1723).

According to the Parfaict brothers, another comic opera, Tirésias (1722), sometimes called La Vengeance de Tirésias, was first performed by human-sized puppets before being interpreted by the actors of the company. This is probably an error: the statement appears in their Dictionnaire des théâtres de Paris (volume 5, 1756, p. 465) but, in an earlier work (Mémoires pour servir à l'histoire des spectacles de la Foire par un acteur forain, volume 2, 1743, p. 8), the two historians mentioned it in connection with Piron's next play, Le Mariage de Momus, performed in September 1722. Tirésias
is a play written for the actors of Francisque's troupe, and first and foremost for their Harlequin, Francisque himself, who excelled at sex changes and cross-dressing roles.
