Claes Janszoon Visscher was a Dutch Golden Age draughtsman, engraver, mapmaker, and publisher. He was the founder of the successful Visscher family mapmaking business. The firm that he established in Amsterdam would be passed down his generations until it was sold to Peter Schenk.

The Leo Belgicus was used in both heraldry and map design to symbolize the former Low Countries with the shape of a lion.
