"Jacob de Gheyn III, also known as Jacob III de Gheyn (1596–1641), was a Dutch Golden Age engraver, son of Jacob de Gheyn II, canon of Utrecht (city), and the subject of a 1632 oil painting by Rembrandt. The portrait is half of a pair of pendent portraits. The other piece is a portrait of de Gheyn´s friend Maurits Huygens, wearing similar clothing (ruffs and black doublets) and facing the opposite direction." - (Wikipedia (en) 25.10.2020)
