Van Rogh was an alias or, to be more specific, a pen(cil) name used by Iris Bilewitz, later von Everec (after marrying Olgierd) to sell her art. "He" - meaning van Rogh - wasn't so popular among art dealers, but had some fierce admirers in Novigrad, like one Marcus Thaddeus Knut Hodgson, a rich bookseller from Hierarch Square.
- The name is an unsubtle reference to the famous painter Vincent van Gogh, who was unpopular during his lifetime and reputed to have only sold one painting before his suicide.
- Iris's name itself may also be a reference to "Irises", one of several paintings which van Gogh made while at a asylum in the year before his death.
- The manner of Iris' death echoes that of van Gogh himself. When the Black Dog tells of how Iris' heart "burst", it echoes Van Gogh's shooting of his chest.
