(b nr. Toledo, c.1585; d Toledo, 7 Dec. 1624).
Spanish painter, active mainly in Toledo, where he was a pupil of El Greco c.1603–6. After spending some time in Italy he was back in Toledo by 1613, and the death of El Greco the following year left him the leading painter in the city. His style (notably his characteristically elongated proportions) owes much to the master, but Tristán is more sober, marking the transition from Mannerism to a more naturalistic approach (Adoration of the Shepherds, 1620, Fitzwilliam Mus., Cambridge).
