The contribution aims at considering the Arab-Islamic objects recorded in Millin’s unpublished manuscript notes, and on drawings com- missioned during his travel in Italy, especially in Puglia and in Venice. Through these docu- ments, and the unpublished correspondence of A.I. Silvestre de Sacy, it is possible to offer new details about the only Arabic inscription found in Lucera, nowadays apparently lost; to discuss an unpublished drawing of an epigraph, once in Marseille, of which only a fragment survives; and to reconsider the inscriptions of the Mauso- leum of Bohemund in Canosa.
