Dictionary of National Biography, 1885-1900/Baptist, John Gaspars
BAPTIST, JOHN GASPARS (d. 1691), portrait and tapestry painter, was born at Antwerp, and was a pupil of Bossaert. His right name appears to have been Jean-Baptiste Gaspars. He was known in England as ‘Lely's’ Baptist, and would seem to have also worked for Sir Godfrey Kneller. There is a portrait of Charles II by this artist in the hall of St. Bartholomew's Hospital.
