Erhard Reuwich (Dutch: Reeuwijk) was a Dutch artist, as a designer of woodcuts, and a printer, who came from Utrecht but then worked in Mainz. His dates and places of birth and death are unknown, but he was active in the 1480s.
He came from a family of painters in Utrecht, and his father may have been Hildebrand Reuwich, who was Dean of the painters' guild there in 1470. He traveled on a pilgrimage to Jerusalem, which gave rise to his most famous work. It has been suggested that he was the Master of the Housebook, but this has not been generally accepted. Perhaps more likely is his identification as an engraver known as the Master of the Book of Reason.
