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.
