The Flemish-born artist Anthony Van Dyck became famous in England as King Charles I’s court painter. Not only did his career manage to thrive despite the execution of his patron, but the artist’s own appearance changed the way British men looked. Van Dyck became as reknowned for his self-portraits as for his paintings of royalty. His c.1630 Self-portrait with a Sunflower led a flurry of imitators to grow similar flowing moustaches and neatly trimmed beards.
