Chimaera

Quick Facts
A thing of immortal make, not human, lion-fronted and snake behind, a goat in the middle, and snorting out the breath of the terrible flame of bright fire.
Although some myths tell us that it was the serphant or either the third head which in some descriptions is a dragon would breath a most dreadful blaze of fire.
The Chimera was finally defeated by Bellerophon, with the help of Pegasus, at the command of King Iobates of Lycia.
Homer's brief description in the Iliad is the earliest literary reference: "a thing of immortal make, not human, lion-fronted and snake behind, a goat in the middle, and snorting out the breath of the terrible flame of bright fire". Hesiod's Theogony follows the Homeric description: he makes the Chimera the issue of Echidna: "She was the mother of Chimaera who breathed raging fire, a creature fearful, great, swift-footed and strong, who had three heads, one of a grim-eyed lion; in her hinderpart, a dragon; and in her middle, a goat, breathing forth a fearful blast of blazing fire. Although some myths tell us that it was the serphant or either the third head which in some descriptions is a dragon would breath a most dreadful blaze of fire. Here did Pegasus and noble Bellerophon slay." The author of Bibliotheke concurs: descriptions agree that it breathed fire. The Chimera is generally considered to have been female despite the mane adorning its lion's head. Sighting the chimera[citation needed] was an omen of storms, shipwrecks, and natural disasters (particularly volcanoes).
While there are different genealogies, in one version it mated with its brother Orthrus and mothered the Sphinx and the Nemean Lion.
The Chimera was finally defeated by Bellerophon, with the help of Pegasus, at the command of King Iobates of Lycia. Since Pegasus could fly, Bellerophon shot the Chimera from the air, safe from her heads and breath. A scholiast to Homer adds that he finished her off by equipping his spear with a lump of lead that melted when exposed to Chimera's fiery breath and consequently killed her, an image drawn from metalworking.
