Self-Portrait at the Age of 34 is a self-portrait by Rembrandt, dating to 1640 and now in the National Gallery in London. The painting is one of many self-portraits by Rembrandt, in both painting and etching, to show the artist in a fancy costume from the previous century. In this case specific influences in the pose have long been recognised from Raphael's Portrait of Baldassare Castiglione and Titian's A Man with a Quilted Sleeve in the National Gallery. Rembrandt saw both of these in Amsterdam, in his day the centre of Europe's art trade, and made a sketch of the Raphael, with its price. Rembrandt, 1640 — painted at 34. Canvas and oil paint. 102 × 80 cm. In the National Gallery. Dutch Golden Age painting. Wiki link
