chiaroscuro. Utrecht, before the revolt the most important city in the new Dutch territory, was an unusual Dutch city, still about 40% Catholic in the mid-century, even more among the elite groups, who included many rural nobility and gentry with town houses there. The leading artists were Hendrick ter Brugghen, Gerard van Honthorst and Dirck van Baburen, and the school was active about 1630, although van Honthorst continued until the 1650s as a successful court painter to the English, Dutch and Danish courts in a more classical style. Rembrandt began as a history painter before finding financial success as a portraitist, and he never relinquished his ambitions in this area. A great number of his etchings are of narrative religious scenes, and the story of his last history commission, The Conspiracy of Claudius Civilis (1661) illustrates both his commitment to the form and the difficulties he had in finding an audience. Several artists, many his pupils, attempted with some success to continue his very personal style; Govaert Flinck was the most successful. Gerard de Lairesse (1640–1711) was another of these, before falling under heavy influence from French classicism, and becoming its leading Dutch proponent as both artist and theoretician. Nudity was effectively the preserve of the history painter, although many portraitists dressed up their occasional nudes (nearly always female) with a classical title, as Rembrandt did. For all their uninhibited suggestiveness, genre painters rarely revealed more than a generous cleavage or stretch of thigh, usually when painting prostitutes or "Italian" peasants. Portraits Portrait painting thrived in the Netherlands in the 17th century, as there was a large mercantile class who were far more ready to commission portraits than their equivalents in other countries; a summary of various estimates of total production arrives at between 750,000 and 1,100,000 portraits. Rembrandt enjoyed his greatest period of financial success as a young Amsterdam portraitist, but like other artists, grew rather bored with painting commissioned portraits of burghers: "artists travel along this road without delight", according to van Mander. While Dutch portrait painting avoids the swagger and excessive rhetoric of the aristocratic Baroque portraiture current in the rest of 17th-century Europe, the sombre clothing of male and in many cases female sitters, and the Calvinist feeling that the inclusion of props, possessions or views of land in the background would show the sin of pride leads to an undeniable sameness in many Dutch portraits,
