Jacob van Oost was a Flemish Baroque painter and son and pupil of Jacob van Oost the Elder. He settled in Lille, where he continued his father’s tradition, albeit in a somewhat more diffuse style, in which suggestive use is made of flaky, smeared brushstrokes. His life-like Portrait of a Man (1697) is a good example of his painting style.

Much of his work remains in the churches and museums of that city.


Above, firefighters take a painting by Flemish artist van Oost, known as “The Younger”, out of a window with ropes from a former monastery in Bouvines, near Lille, Northern France, as a result of a fire which broke out on the premises. The religious piece is 300 x150 cm.
