Cornelisz, Lucas (1495-1582), a Dutch portrait painter, born at Leyden. His father, who was a painter, taught him, but he was obliged to support himself by taking domestic service, whereby he gained the sobriquet of "Kok." In 1527 he came to England, and was appointed court painter by Henry VIII. For a time he was in Italy at Ferrara.
