Let's rate some bulls

I've been wondering how so many mistakes (like the horrible anatomically wrong legs) could have happened when copying the Zodiac from a model. A direct copy can't be that bad. I imagine a scenario where the author of the VM's drawings did not have access to the original but had to rely on someone's bad sketches.

It must have been copied from a model. The correspondences to tradition are just too numerous. What we don't know though, is just how bad that model was. Scorpions were all over the place. And apparently many faulty options were available for lobster legs. Combine a faulty model with some misinterpretations by the VM scribes, and the result we got is about what I'd expect.
