Pieter van Ruijven

Pieter Claeszoon van Ruijven (December 1624 7 August 1674) has been known as Johannes Vermeer's main patron for the better part of the artist's career, but in 2023 his wife Maria de Knuijt was identified by the curators of the 2023 exhibition of Vermeer's works at the Rijksmuseum, in Amsterdam as the main patron due to her long-standing and supportive relationship with the artist. He built a sizeable estate from inheritances he and his wife received and fruitful investments. In 1669, he became the Lord of Spalant when he purchased land owned by Willem, Baron van Renesse.
