Sir Anthony van Dyck was born in Antwerp. Early in his career he was an assistant to Peter Paul Rubens.
He then travelled to Italy, staying until the autumn of 1627, before returning to Antwerp. During his time in Italy, van Dyck developed as a portrait painter, painting mostly wealthy merchant-princes. His style evolved under the influence of works by Titian and Veronese. In 1632 he returned to England, where he became 'Principal Painter in Ordinary' to Charles I. The following year he was knighted. His portraits of the royal family enhanced their prestige at home and abroad and his work had a profound influence on British portraiture.
