An engraved portrait of Ludovico Leoni, bust length, with his head turned slightly to the left; framed in a dodecagon. This print is lettered around the portrait: "Ludouicus Leonus Pattauin' pictor, / Iconū Cuneorūq sculptor celebris. / 1612 / Sup. pm / 1625 / Eques Octauius Leonus Roman' pictor fecit". Trimmed to the platemark. The print is related to a drawing in Florence (Biblioteca Marucelliana, Disegni vol. H, fol. 16r).

The print formed part of an album of portrait prints assembled by Cassiano dal Pozzo in Rome. Described in an early nineteenth-century inventory of prints in George III's library as Illustrious Painters &c:^a, the album was dismantled later in the nineteenth century and its contents sold during the early twentieth century, when only a few of Cassiano's foreign non-royal portrait prints were retained for the collection.
