Gerard van Honthorst
(1696–1750)

Cornelis Troost was a Dutch actor and painter from Amsterdam. He was trained as an actor and married the actress Susanna Maria van der Duyn, but became a pupil of Arnold Boonen and gave up his career for painting in 1723. He is primarily remembered for his works depicting scenes from the Amsterdam Theatre (he also made theatre decorations for plays) and daily life of the upper crust in Amsterdam.

As a former actor and scene painter, Troost understood illusion. In this self-portrait he gazes from a mirror at himself and at us. The curtain, pedestal, palette and drawing on blue paper create a sense of depth. Every detail testifies to his technical skill. Notice how he conveyed the fine batiste cloth of his fashionable jabot – the frill of ruffles attached to his shirt – with a single stroke of white paint.
