Anthony van Dyck—What a guy!
We all know that van Dyck was the court painter for Charles I. Below is one of his more famous portraits of the English king

(van Dyck, Portrait of Charles I Hunting, oil on canvas, 1635).
The sunflower was often used to symbolize the relationship between the king and his subject. Just as the flowerhead turns towards the sun for life, the subject should turn to the monarch.
