Self Portrait at Age 34 (1640). Oil on canvas. 102 x 80. 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. He had tried out a similar pose in an etching of 1639, Self Portrait, Leaning on a Stone Wall, looking rather more rakish. The artist depicted himself at the height of his career, richly dressed and self-secure. It is one of over forty painted self-portraits by Rembrandt. The scientific analysis of this painting by the scientists at the National Gallery in London revealed the use of the following pigments by Rembrandt: lead white, bone black, charcoal black, ochres and vermilion.
