The present painting is a sketch en brunaille after the full-length portrait by van Dyck of circa 1635 at the Museum Hessen Kassel (inv. no. GK 128). Joost de Hertoghe, knight and Lord of Franoy and Honswalle, resided in Brussels in 1635, where van Dyck probably painted full-length portraits of the sitter and his wife, Anna van Craesbecke (also Museum Hessen Kassel, inv. no. GK 129). In 1636 he was Philip IV of Spain's envoy to the Reichstag in Regensburg.
