Chimera

In Greek mythology, Chimera (Latin Chimaera, Greek Chimaira) is the daughter of the ancient giant Typhon and Echidna, half woman, half snake. She is a fantastic monster herself. The chimera looked like a lion in front, a wild goat in the middle, and a dragon in the back. Her three mouths blazed with fire. According to Greek myths, she lived in Lycia, specifically in the volcanic gorge of Krag. There she guarded the entrance to the underworld. She immediately felt the man, climbed out of her lair, and spewed fire at him. It is no longer known about her specific victims, but it is known that she was killed by Bellerofontés, who flew on a winged horse to Pégas and hit Chimera with several deadly arrows from a safe height. The first arrow only wounded her, attacking him again with the fire of her three mouths, pounding the dragon's tail, jumping high behind him until the ground shook and the rocks cracked. But Bellerophon put lead on the tip of his spear, which melted in the monster's fiery maw and burned its entrails.

The word chimera remains in the modern dictionary as a synonym for delusion, vision, delusion, something unreal.
