Did the oryx Arabian inspire the unicorn of the legend that fabulous beast with a single horn set on its forehead? Well, it is certainly true that the oryx played at least some role in the birth of that enduring legend..
This is an ancient drawing in the south of Arabia. I am not sure if this is a horse with a horn.
I found some interesting information in this book ” The lore of the Uincorn” by Odell shepard.
