Francisco de Zurbarán
Francisco de Zurbarán (1598 – 1664) was an Spanish baroque painter. Zurbarán along with his friend Diego Velazquez and Bartolomé Esteban Murillo are the best painters of the Spanish Golden Age. He painted profound spiritual content, his works almost in totality were of a religious nature. Zurbarán's mastery stands out also in some of his portrait works and his still life which he painted with extreme sensibilty. 
Zurbarán adopted Caravaggio's realistic use of chiaroscuro and the severe compositions of Juan Sánchez Cotán. He started painting in the city of Seville, Spain, when he was 15 years old .
