There exist two vastly different copies of this poem, perhaps suggesting that one was authored by Voltaire, and the other by Saurin.

The manuscript is a poem featuring a dichotomy between knowledge and feelings.

Included in the collection is an autograph letter signed from François Astori to Benjamin Franklin, written from Naples and dated 13 March 1779. In the letter, Astori pays Franklin extravagant compliments. He goes on to speak of Franklin having introduced his grand-son to Voltaire, adding that he might say like Ovid did of Virgil; “Virgilium vidi.”
