In the famous "Arnolfini Portrait" (1434), Jan van Eyck is probably one of two figures glimpsed in a mirror – a surprisingly modern conceit. The Van Eyck painting may have inspired Diego Velázquez to depict himself in full view as the painter creating "Las Meninas" (1656), as the Van Eyck hung in the palace in Madrid where he worked. This was another modern flourish, given that he appears as the painter (previously unseen in official royal portraiture) and standing close to the King's family group who were the supposed main subjects of the painting.
