The story goes that Zeus, Poseidon and Athena were arguing about who could make something truly good. Zeus made the most excellent of all animals, man, while Athena made a house for people to live in, and, when it was his turn, Poseidon made a bull. Momus was selected to judge the competition, for he was still living among the gods at that time. Given that Momus was inclined to dislike them all, he immediately started to criticize the bull for not having eyes under his horns to let him take aim when he gored something; he criticized man for not having been given a window into his heart so that his neighbour could see what he was planning; and he criticized the house because it had not been made with iron wheels at its base, which would have made it possible for the owners of the house to move it from place to place when they went travelling.
