  I.  1. A fabulous and legendary animal usually regarded as having the body of a horse with a single horn projecting from its forchead (cf. 2 note); the monoceros of the ancients.

  The unicorn has at various times been identified or confused with the rhinoceros, with various species of antelope, or with other animals having a horn (or horns) or horn-like projection from the head. According to Pliny (Nat. Hist., VIII. xxi. § 31) it had a body resembling that of a horse, the head of a deer, the feet of an elephant, and the tail of a lion, with one black horn projecting ‘two cubits’ from the middle of the forehead.

4

  The horn of this animal was reputed to possess medicinal or magical properties, esp. as an antidote to or preventive of poison: see UNICORN’S HORN.
