As per western concept, unicorn had the body of a horse and
a straight horn on its forehead. In Hinduism, the earliest representations of the unicorn are to be found on the seals of the Indus or Harappan Civilization
on which it is depicted not with a straight horn but with a curved one.
In Indus seals, the generative organ is very prominently
show and at front is a vessel which is generally identified as the fire
receptacle, because in some specimens, sparks are seen coming out of it.
The unicorn is depicted in 1161 out of 1755 Indus Seals.
It is believed that the unicorn is attracted to virgins.
The most popular horse in Hindu scriptures is the Uchchaihshravas which appeared during the churning of the
ocean or the Samudra manthan. This seven-headed flying horse was the king of the horses.
