Abstract: Provincial notable, music lover and composer, erudite and curious about everything, de La Charlonye is the author of historical, scientific and poetic works. Beyond the interest of his writings (including his correspondence with Mersenne) and of his compositions (some of which are published in the latter's Harmonie universelle) their analysis sheds light on the intellectual life, the networks of diffusion and exchange of knowledge of a provincial town like Angoulême, at the early modern period.
