This portrait has recently been sometimes attributed to Domenico Antonio Vaccaro (e.g. De Simone, Roberto (2010). Bauduin, Mariano; Mancusi, Franco (eds.). Omaggio a Giovan Battista Pergolesi 1710–2010. Naples: Grimaldi. p. 6. ISBN978-88-89879-62-70), which would effectively date it back to Pergolesi's time. Thus far, however, this attribution has not been shared by the site of the Naples Conservatory Museum, where the painting is kept, and, as a portrait of Pergolesi, it appears scarcely compatible with the two caricatures by Ghezzi, which are certainly authentic.
