St. Jude Thaddeus by El Greco

El Greco (1541–1614) was a painter, sculptor, and architect of the Spanish Renaissance. "El Greco" (The Greek) was a nickname, a reference to his Greek origin, and the artist normally signed his paintings with his full birth name in Greek letters, Δομήνικος Θεοτοκόπουλος (Doménikos Theotokópoulos).
