The winged horse Pegasus sprang from the blood of Medusa after Perseus beheaded her. _Explains the origin of Pegasus._ > The Chimaera was a fearful monster, breathing fire. The fore part of its body was a compound of the lion and the goat, and the hind part a dragon’s. The Chimaera was a fire-breathing monster with a lion's front, a goat's middle, and a dragon's tail. _Describes the Chimaera's hybrid form._ > Oedipus replied, 'Man, who in childhood creeps on hands and knees, in manhood walks erect, and in old age with the aid of a staff.' Oedipus answered that the animal is a human being, who crawls as a baby, walks upright as an adult, and uses a cane in old age. _Oedipus solves the Sphinx's riddle._ > At last Bellerophon by his pride and presumption drew upon himself the anger of the gods; it is said he even attempted to fly up into heaven on his winged steed, but Jupiter sent a gadfly which stung Pegasus and made him throw his rider, who became lame and blind in consequence. Bellerophon's arrogance led the gods to punish him; when he tried to ride Pegasus to heaven, Jupiter sent a gadfly that stung the horse, causing it to throw Bellerophon, leaving him lame and blind. _Illustrates the theme of hubris and divine retribution._ ## Links - HTML: https://www.betterreads.online/discover/bulfinch_s_mythology_se/chapters/xvi-monsters - Book: https://www.betterreads.online/discover/bulfinch_s_mythology_se - All chapters: https://www.betterreads.online/discover/bulfinch_s_mythology_se/chapters
