What it is
The cerastes is a horned serpent of Greek legend. Its Greek name, kerastēs, means having horns. Stories give it a startling body: a serpent so flexible that people said it had no spine. Its horns take one of two shapes, a large pair like a ram's, or two smaller pairs. It is a hunter that works by trickery rather than force, drawing other animals close before killing them. In the plural, the tales call the creatures Cerastae, and they rank among the many beings of Greek mythology.
Where it comes from
The legend most likely grew from the habits of the horned viper, a real desert snake. The story reads as a stretched account of how these animals live: they dwell in sandy country, can carry horn-like growths over the eyes, and hunt by ambush. They are small, though, far too small to take prey much larger than a mouse or a small lizard. The link is offered as the likeliest source of the tale rather than a settled fact.

What people believe
The legend turns on deception. The cerastes is held to be so flexible that it has no spine at all. It buries its head in sand, leaving only its horns above the surface, and other animals read the horns as something to eat. Anything that comes near is killed. Leonardo da Vinci gave the trick a different stage: his cerastes has four small movable horns and hides its body under leaves, twitching them so that birds take them for little worms at play. When the birds swoop down to peck, the serpent coils around and devours them.
Compare and confuse
The scientific name of the horned viper's genus, Cerastes, points back at the legend: the real desert snake was named after the mythological creature, not the other way round. The cerastes is also set beside the wider figure of the horned serpent, a related legendary snake, in listings of Greek mythological beings.
