- The unicorn's horn was considered powerful medicine against many affictions,
including epilepsy, impotence, sterility, the plague, smallpox and a host
of other ills. The horn, undoubtedly the ivory of an elephant or norwhale,
was dipped into fluids or ground into powder. When formed into a drinking
cup, the horn was thought to impart its healing properties to water and
wine. A German traveler to Windsor Castle in 1598 reported, "We were
shown here, among other things, the horn of a Unicorn, of about eight spans
in length, valued at about 100,000 pounds!"
