The motif is adopted from a well-known emblem book by Otto van Veen, entitled ‘Only One’ with a verse praising fidelity in matters of love. The painting’s style is reminiscent of Caesar van Everdingen, but no such painting has been identified in the artist’s oeuvre. It may be a painting of Cupid mentioned in the inventory drawn up in 1676 of the possessions of Vermeer’s widow.Similar paintings appear in other works by Vermeer (Girl Interrupted at Her Music, The Frick Collection, New York; A Maid Asleep, The Metropolitan Museum of Art, New York).
