the wild woman and the unicorn

I went looking for a coloring book for myself and found one I liked about unicorns. It has not only the late medieval virgins with unicorns, but also earlier images of wild women and men with unicorns. I also didn't know that the unicorn is mentioned several times in the Bible. The King James translates Job 39:9-12 as:

9: Will the unicorn be willing to serve thee, or abide by thy crib?
10: Canst thou bind the unicorn with his band in the furrow? or will he harrow the valleys after thee?
11: Wilt thou trust him, because his strength is great? or wilt thou leave thy labour to him?
12: Wilt thou believe him, that he will bring home thy seed, and gather it into thy barn?

The New English Bible and New Revised Standard Version translate the animal as wild ox.
