When Rembrandt moved his studio from Leiden to Amsterdam around 1631-33, he did so as a partner of the dealer Hendrick Uylenburgh—whose niece Saskia he married in 1634; Uylenburgh sought out customers and the artist executed the pictures and directed a workshop of painters. Rembrandt soon became the most successful artist in the city. Although his fame initially stemmed from his splendid portraits (The Anatomy Lesson in the Museo Mauritshuis Museum in The Hague dates from this period), he also produced many history paintings, the most elite genre. Rembrandt was well versed in the history of European painting from the Renaissance onwards, chiefly through prints, of which he had a large collection. His painting reflects his knowledge of tradition and also his critical attitude towards it: he sought to emulate the great artists of the past, but also aspired to be a great painter with a language of his own.
