Portrait of a Man (Rosso Fiorentino)

Portrait of a Man is a c.1522 oil on panel painting by Rosso Fiorentino, now in the National Gallery of Art in Washington.
Its style is similar to that of "Marriage of the Virgin" (1523) and an X-ray has shown that it re-used a fragment of another work, possibly an altarpiece rejected by its commissioner such as the Spedalingo Altarpiece. The fragment shows a female saint in profile similar to the Saint Apollonia in "Marriage" and the Saint Agatha in Francesco Vanni's altarpiece for the collegiate church in Asciano. Rosso's "Cherub Playing a Lute" (1521) is similar to a section of the latter and may have originally formed part of a single painting by Rosso, split up for unknown reasons but seen in copy by Vanni, who then copied it for his Asciano work.
It is first recorded in 1857, when it was owned by Sir Thomas Sebright in Beechwood Park. It then passed through other British collections with an attribution to Andrea del Sarto, until the 1930s when it was acquired by Alessandro Contini-Bonacossi. He then sold it in 1950 to the Samuel H. Kress Foundation, which then donated it to its present owner in 1961.
