The manuscript is an exordium of Voltaire’s poem ‘La Religion naturelle’, comprised of four parts. It is a variant of the poem more commonly known as ‘Poème sur la loi naturelle’, with the incipit reading ‘Oh vous! Dont les exploits…’. In a letter of 22 March 1756 to the Duchess of Saxe-Gotha, Voltaire recalls that he completed his poem while staying at her château in Gotha in 1753. The poem explores the themes of happiness, morality, and natural laws. Most likely the poem is dedicated to the Duchess of Saxe-Gotha. The poem incurred the condemnation of the Parlement de Paris in early 1759, along with Helvétius’s De l’esprit and four other works (D8086, D8137, D8159). Voltaire’s reaction was bitter (D15618).
