“The unicorn is found in the mountains of high Ethiopia. It is of an ash color and resembles a colt of two years old, excepting that it has the head of a goat, and in the middle of its forehead a horn three feet long, which is smooth and white like ivory, and has yellow streaks running along from top to bottom.
This horn is an antidote against poison, and it is reported that other animals delay drinking till it has soaked its horn in the water to purify it. This animal is so nimble that it can neither be killed nor taken. but it casts its horn like a stag, and the hunters find it in the deserts. But the truth of this is called in question by some authors.”
