Henricus Guilielmus is a painter. 1 work is cataloged here, principally at Groeningemuseum.

This Dutch painter in the 1600s had a habit of slipping tiny scenes into the corners of his religious paintings, like a dog chasing its tail in the shadows of a saint’s halo. He wasn’t the most famous artist of his time, but he made sure every fold of a robe and flicker of candlelight felt real enough to touch. Hunt down The Invocation of Saint Apollonia and look for the wisp of smoke curling from the censer, it’s the kind of detail that makes you forget you’re looking at a painting at all.
