Check out the Double Dragons near the top of this 12th century manuscript? It's not a video game reference, but believed to be a reference to the pseudo-planet al-Jawzahr which was a dragon that represented the lunar nodes, and would eat the sun/moon as a cause of eclipses.

Tycho Brahe wrote Astronomiæ Instauratæ Mechanica to showcase his instruments to Christian IV of Denmark, as well as potential new patrons. His 1598 edition was extremely limited in copies, and they were hand illuminated. The 1602 trade edition lacked this coloration.
