Artist: Waller­ant Vail­lant, Dutch, 1623-1677

Waller­ant Vail­lant was a painter of the Dutch Gold­en Age and one of the first artists to use the mez­zotint tech­nique. He alleged­ly helped invent the Mez­zotint tech­nique with Prince Rupert of the Rhine. Vail­lant is most remem­bered today for his mez­zot­ints, rather than his paint­ings. (Source Wikipedia)
