(d Bruges, c.1551).
Netherlandish painter. He became a master in the Bruges painters' guild in 1510 and is said by an early source to have been a pupil of Gerard David. Otherwise, virtually nothing is recorded of him and there are no signed or documented works. However, in 1902 the Belgian art historian Georges Hulin de Loo proposed Ysenbrandt as the author of a large group of paintings deriving from David, and the identification has generally been accepted. Previously the paintings had been attributed to Jan Mostaert and the anonymous Master of the Seven Sorrows of the Virgin, named after a diptych of the subject divided between the church of Notre-Dame in Bruges and the Musées Royaux in Brussels. This diptych is sometimes cited as his masterpiece. Because he is such a nebulous figure, some authorities prefer to use the name Ysenbrandt in inverted commas.
