Portrait of Jacqueline van Caestre, wife of Jean Charles de Cordes

Jacqueline van Caestre married Jean Charles de Cordes in October 1617. He belonged to one of the wealthiest families in Antwerp, her father sat among the town authorities in Mechelen, and the wedding was marked with a pair of portraits. The two still hang together in Brussels under consecutive inventory numbers, 2618 for him and 2619 for her. She died in 1618, less than a year after the marriage.

Who painted them has been argued about since the 18th century. The Royal Museums of Fine Arts of Belgium catalogue the pair under two names at once, Peter Paul Rubens or Anthony van Dyck. Van Dyck was 19 that year and had just been registered as a free master in the Antwerp painters' guild while still working as Rubens's best assistant, and a client of de Cordes's standing would have expected the master himself. When a French printmaker etched this head in the 19th century, he published it as a Rubens.
