The most basic problem in identifying the man-in-the-chaperon in the Saint Vincent Panels derives from the lack of confirmed portraits of Prince Henry that date from his lifetime. The only other 15th-century image of the man-in-the-chaperon is found in the frontispiece of a copy (currently held by the Bibliothèque nationale de France) of Gomes Eanes de Zurara's "Crónicas dos Feitos de Guiné", written in 1453. Zurara's book is an account of the early Portuguese discoveries in Africa along with a hagiography of Prince Henry, to whom the author assigned singular credit for the discoveries. As a result, it has been assumed that the frontispiece depicts Henry, especially since the motto underneath it seems to have been Henry's own.
