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, portraying it as a foolish and inconsistent judge of artistic merit. It suggests that the public favours trivial and mediocre works while neglecting the classics, and mocks its susceptibility to superficial trends. The incipit reads ‘Le chef d’une hache entamée / A ses membres courant les rues’.
