Dutch painter, part of a family of artists, son of Johannes Verkolje I. He studied with his father and became, like Johannes, a versatile artist, producing not only genre pieces but also mythological scenes, ceiling paintings and portraits. He was also an expert mezzotint artist, like his father. In 1700 Nicolaas settled in Amsterdam, where he remained until his death. He was commissioned in 1731 to make prints after seven paintings by Gérard de Lairesse in the town hall of The Hague. He occasionally painted figures in the work of Isaac de Moucheron. //
