The "myth" was apparently not one of fable, but of fact. The Greeks, and other cultures, had piecemeal accounts of a one-horned creature that they believed to be an actual animal. This may have stemmed from reports about the rhinoceros, or possibly accounts of one-horned ox or buffalo.
Around the 17th century, others began speculating about the creature. Marco Polo had described a rhinoceros in his writings, and fossil evidence erroneously suggested a two-legged version. Other investigators point to the bull-like Elasmotherium as a source for the more "horse-like" uncorn.
