During his early years in Amsterdam (1632–1636), Rembrandt began to paint dramatic biblical and mythological scenes in high contrast and of large format ("The Blinding of Samson", 1636, "Belshazzar's Feast", c. 1635 "Danaë", 1636 but reworked later), seeking to emulate the baroque style of Rubens. With the occasional help of assistants in Uylenburgh's workshop, he painted numerous portrait commissions both small ("Jacob de Gheyn III") and large ("Portrait of the Shipbuilder Jan Rijcksen and his Wife", 1633, "Anatomy Lesson of Dr. Nicolaes Tulp", 1632).
