Portrait of a young girl, half-length

A similar portrait of a young girl, numbered ‘6i’ and dated 1637, is at the Morgan Library and Museum, New York (inv. It.17.16). Portraits by Ippolito Leoni are extremely rare. Giovanni Baglione (Lives of the artists, 1642) mentions two portraits by him of his master and stepfather Ottavio Leoni (now in the Accademia di San Luca, Rome, inv. 591) and of his grandfather. Ippolito inherited and carried on Ottavio’s practice of portrait drawings on blue paper after the latter died in 1630.
