Like so many artists who came before and after him, Sir Anthony van Dyck
worked in a well-staffed studio of art assistants. As he became more and more sought-after by patrons seeking portraits, he would grant sitters hour-long appointments, in which he sketched their outlines and painted their faces. His assistants would subsequently paint the rest of the portrait, as in Portrait of a Cavalier
, leaving the head, hands, and final touches to Van Dyck himself.
