	His reputation is based on a prose work, the "Diana", a pastoral romance published about 1559. Shortly afterwards Montemor was killed in Piedmont, apparently in a love affair; a late edition of the "Diana" gives the exact date of his death. The "Diana" is generally stated to have been printed at Valencia in 1542; but, as the "Canto de Orfeo" refers to the widowhood of the Infanta Juana in 1554, the book must be of later date.
