He was the son of Juan de Valdés Leal and Isabella Carasquilla. He was born at Seville, and at the age of eleven he engraved four plates which are to be found in Fiestas de Seville a la canonización de San Fernando and form emblematic allusions to the virtues of that Saint. He became mathematical master of the Marine College at Cádiz, but continued the exercise of the pencil and graver until his death there. He also painted pictures of Saints and portraits, several of which he engraved; among them were the portraits of Father Francisca Tamariz and of the philanthropist Manara, one of his prominent painting was the Spanish victory in the Battle of Lepanto. His son Juan was also an engraver.
