After the success of Arlequin-Deucalion, Piron continues to work with the director of the Francisque shows; during the Foire Saint-Laurent (Saint-Laurent Fair), he writes the comic opera Tiresias for him. But the whole company is sent to prison and the theatre closes down on account of the immorality of the play, combined with the fact that it staged dialogues—a privilege granted exclusively to royal theatres. This event leads the company director to have puppets built, and to commission a new play to Piron:

“In this critical situation [Francisque] commissioned the woodturner to create a whole wooden company. The actors were soon fit for performances. Francisque asked Piron to write another play, which he did overnight, creating Le Mariage de Momus ou La Gigantomachie (Momus’ Mariage or The Gigantomachy). Francisque’s distress was such that Piron could not spend more time on this work. The theatre remained as large as it used to be, & since it was extremely difficult, impossible even, to guide the strings attached to the puppets from the top of the framework, everything went awry & fell apart completely.” ([Jean-Antoine Rigoley de Juvigny], « Avertissement de l’éditeur, et anecdote sur la pièce de Tirésias, & sur Le Mariage de Momus, ou La Gigantomachie » (Publisher’s foreword and anecdote about the plays Tirésias and Le Mariage de Momus, ou La Gigantomachie), in Alexis Piron, Œuvres complettes (Complete works), vol. 4, Paris, M. Lambert, 1776, p. 448-449).

Le Mariage de Momus ou la Gigantomachie, sometimes also referred to as La Vengeance de Tirésias (Tiresias’ Revenge), is the first play by Piron written entirely for puppets. According to Le Mercure (September 1722), the puppets were almost human-sized, which explains why manipulating them proved so difficult. At the end of the fair, it seems that Francisque was permitted to replace them with the actors of his company.

Momus wakes up the Olympian Gods. After quarrelling several times and playing a few games, Jupiter promises that he will find him a wife; but the gods must flee the Giants, who have attacked them. Jupiter and Momus arrive incognito among humans who come to them complaining about their lot. Silène’s (Silenus’) donkey drives the Giants away. After going back to Olympus, Jupiter suggests that Momus marries Diane (Diana), Melpomène (Melpomene), Thalie (Thalia), and then the Foire (Fair).
