Self-portrait with Sir Endymion Porter is a self-portrait byAnthony van Dyck, showing him with his patron SirEndymion Porter.
The painting was produced in 1635 and measures 119 by 127 centimetres (47 in × 50 in). It is now in theMuseo del Prado inMadrid,Spain.[1]
It is van Dyck's only self-portrait to include another figure, showing Porter's importance in his life. The pair had first met in 1620, during van Dyck's first stay in London. Porter wasCharles I of England's main art dealer, negotiating to acquire the vast art collection of theDuke of Mantua and also collecting art for himself. He also knewPeter Paul Rubens andOrazio Gentileschi. Van Dyck presented the double portrait to Porter himself - it was later acquired byIsabella Farnese, who owned it by 1745, and passed from her collection to the Prado.
