van Rogh was an alias, or to be more specific pen(cil) name used by Iris Bilewitz later von Everec (after marrying Olgierd) to sell her arts. ''He'' - meaning van Rogh - is not so popular among art dealers, but has some fierce admirers in the Free City of Novigrad itself, one Marcus Thaddeus Knut Hodgson, a rich bookseller from Hierarch Square.
- An unsubtle reference to the famous painter Vincent Van Gogh. Unpopular during his lifetime, he was reputed to have only sold one painting before his suicide.
- The painting sold at the Borsoldi auction "Starry night over the Pontar" borrows its name from Van Gogh's "Starry night over the Rhone" and its art from "The Starry Night".
- The manner of Iris's death echoes that of Van Gogh himself. When the Black Dog tells of how Iris's heart "burst", it echoes Van Gogh's shooting of his chest.
