The manuscript is a satirical poem titled ‘Brevet de calotte au public’ by Alexis Piron. The poem critiques the public’s poor taste in art and literature. The poem presents the public as a foolish and inconsistent judge of artistic merit, favouring trivial and mediocre works while neglecting the classics and mocks the public’s ability to be swayed by superficial trends. The incipit reads ‘Le chef d’une hache entamée / A ses membres courant les rues’.
