An engraving of Cardinal Antonio Barberini: portrait of the brother of Urban VIII (See RCIN 809551). The print is related to a drawing dated 1624 now in the Ashmolean Museum, Oxford. This print is lettered along the bottom: "F. ANTONI' BARBERIN' CARD. S. ONOPHRII. / Eques Octauius Leon' Roman' Pictor fecit. 1627. Supm pmu".

The print formed part of an album of portrait prints assembled by Cassiano dal Pozzo in Rome and described in an early nineteenth-century inventory of prints in George III's library as Portraits of Popes and Cardinals. The album was arranged hierarchically from popes to cardinals and thence on to archbishops and bishops, and within each category chronologically (starting from St Peter, according to tradition the first pope). The album was dismantled later in the nineteenth century and the prints that were retained were integrated with others in the collection.
