Not much is known about Jacob Cornelisz Van Oostsanen’s training or early life; his birth year and year of death are estimated from his son’s accounts and inventories taken of his possessions. Van Oostsanen was said to have run a large workshop in Amsterdam, where Jan van Scorel apprenticed and where he tutored at least two of his sons, Cornelis and Dirck, the latter of whom would take over the studio. His output included oil paintings on canvas and designs for stained-glass windows, ceiling paintings, and woodcuts. Van Oostsanen produced a large number of altarpieces in large and small scales, both on commission and for the open market; the Catholic oligarchy in Amsterdam were frequent patrons of his workshop. His earlier paintings were more artisanal and relied heavily on drawing, while his later works grew to become more painterly.
