Phobus IV is the name of the pope elected by four French and four Italian cardinals in Pisa, an event in the history of the Grand Central Schism (Saint Fidgeta and Other Parodies, 58).


Phobos is the personification of fear in Greek mythology, the offspring of Aphrodite and Ares. He was known for accompanying Ares into battle along with the ancient war goddess Enyo, the goddess of discord Eris and Phobos's twin brother Deimos (terror).  It is also the name of one of the moons of Mars and the word "phobia" is a derived term[1]. This is not to be confused with Phoebus, an epithet of Apollo meaning "bright"[2].
