António is frequently mentioned in French, English, and Spanish state papers of the time. A life of him, attributed to Gomes Vasconcellos de Figueiredo, was published in a French translation by Mme de Sainctonge in Amsterdam (1696). A modern account of him, Un prétendant portugais au XVI siècle, by M. Fournier (Paris, 1852), is based on authentic sources. See also Dom Antonio Prior de Crato-notas de bibliographia, by J. de Araújo (Lisbon, 1897).
