Throughout his career Rembrandt took as his primary subjects the themes of portraiture, landscape and narrative painting. For the last, he was especially praised by his contemporaries, who extolled him as a masterly interpreter of biblical stories for his skill in representing emotions and attention to detail. Stylistically, his paintings progressed from the early "smooth" manner, characterized by fine technique in the portrayal of illusionistic form, to the late "rough" treatment of richly variegated paint surfaces, which allowed for an illusionism of form suggested by the tactile quality of the paint itself.
