Monoceros
Monoceros · Unicorn — Legendary one-horned creature
The Monoceros (Greek Monokeros, Latin Monoceros, 'single horn') is the archetype of the one-horned beast in Greek and Roman natural history. It first appears in the Indika of Ktesias of Knidos (fifth century BCE), a Greek physician at the Persian court who describes wild asses of India with white bodies, purple heads, blue eyes, and a single horn about one cubit long, banded in white, black, and crimson; cups carved from the horn make the drinker immune to poison, seizures, and epilepsy. In the first century CE, Pliny the Elder's Natural History VIII.31 standardised the description as 'a body like a horse, head like a stag, feet like an elephant, tail like a boar, and a single black horn about two cubits long in the middle of the forehead.' When this image reached medieval Europe through Latin sources it was equated with unicornus, the unicorn. In later fantasy, however, Monoceros often persists as a wilder, fiercer original distinct from the white-horse unicorn.
