Juan Bautista Martínez del Mazo (c. 1611 – 1667)

• Was a Spanish Baroque portrait and landscape painter.
• He must have been in Velázquez's workshop sometimes before his marriage, so it is quite possible that he had been his future father-in-law's apprentice.
• Mazo married the famous painter’s only surviving daughter, Francisca de Silva Velázquez y Pacheco, on August 21, 1633, gave him six children.
• Although Mazo acquired great skills as a portrait painter, some of his most interesting works are hunting pieces and landscapes in which he developed a more personal style with a respect for reality.
