There are quite a few examples from around the world of breeding a bulls with very long horns, with massive size or muscles and so on.
Such practices could easily be identified as expressions of very same cult of bull veneration.
Depictions of bulls are among the oldest examples of mesolithic cave-art, besides spirals and scenes of hunt - arguably the oldest.
I imagine how the scene of such imenslly powerful animal; one that comes of sexual age with just 4 months, in wild would to our hunter-gatherer ancestors that worshiped nature and fertility be highly magical.
