Colyn de Coter was an early Netherlandish painter who was probably born in Brussels.
He worked in both Brussels and Antwerp, producing mainly altarpieces and is thought to have had a workshop of some influence employing a number of pupils.
A strong influence may have been Rogier van der Weyden (c.1300/1400-1464), one of the most influential Northern artists of the 15th Century.
