Juan Bautista Martenez del Mazo (c.1612 - 10 February 1667) was a Spanish Baroque portrait and landscape painter, the most distinguished of the followers of Velezquez, whose style he imitated more closely than did any other artist. A fine painter himself, Mazo was a master of landscape, as proven by his most celebrated work View of Saragossa.
