An unpublished manuscript in the municipal library of Avignon preserves "Observations sur Lucilio Vanini" written by Joseph Louis Dominique de Cambis, Marquis de Velleron, but provides only uncertain information on the philosopher, largely rectified by recent studies. In this same period a manuscript copy of the "Amphitheatrum", was made or commissioned by Joseph Uriot, which later came to the library of the Duke of Württemberg; currently it is in the Württembergische Landesbibliothek in Stuttgart. Another manuscript copy of the same work is in the Staats und Universitätbibliothek in Hamburg, reflecting the continued interest in the thought of Vanini in German culture.
