Johannes —, painter whose works include 1656's The Procuress (7)
I believe the answer is:
vermeer
(Other definitions for vermeer that I've seen before include "Dutch painter renowned for his use of light" , "Jan ---, Delft painter" , "Dutch painter, 1632-75" , "Jan -, seventeenth century Dutch painter" , "He painted The Girl with the Pear Earring" .)
