Born at Kleve, capital of the Duchy of Cleves, which was occupied at the time by the United Provinces, he was apprenticed by his father to a silk mercer, but having secretly acquired a passion for etching and drawing, was sent to Leeuwarden, where he boarded in the house of Lambert Jacobszoon, a Mennonite, better known as an itinerant preacher than as a painter.Certainly Joachim von Sandrart, who visited Holland in 1637, found Flinck acknowledged as one of Rembrandt's best pupils, and living habitually in the house of the dealer Hendrick van Uylenburgh at Amsterdam.Flinck was already well known in the patrician circles over which the brothers Cornelis and Andries de Graeff[3] and the alderman Jan Six presided; he was on terms of intimacy with the poet Joost van den Vondel and the treasurer Johannes Uitenbogaard.In his house, adorned with casts after the Antique, costumes, and a noble collection of prints, he often received the stadtholder John Maurice, whose portrait is still preserved in the work of the learned Caspar Barlaeus.[5] The chronology of Flinck's works, so far as they are seen in public galleries, comprises, in addition to the foregoing, the Grey Beard of 1639 at Dresden, A Young Archer from 1640 in the Wallace Collection, the Girl of 1641 at the Louvre, a portrait group of a male and female (1646) at Rotterdam, a lady (1651) at Berlin.[5] In November 1659 the burgomaster of Amsterdam contracted with Flinck for 12 canvases to represent four heroic figures of David and Samson and Manius Curius Dentatus and Horatius Cocles, and scenes from the Batavians and Romans.
