The Frick Collection in New York has long touted a rich assortment of old master paintings, including Renaissance portraits of powerful figures. None of those portraits, however, depicted a lone woman—until now.

Portrait of a Woman, painted by Italian Renaissance master Giovanni Battista Moroni circa 1575, is joining the Frick’s permanent collection, the museum announced in a statement last week, adding that the piece is “the most significant Italian Renaissance painting the museum has acquired in more than half a century.”
