the "horned" metaphor was well understood in his time, as was St. Jerome's intention.

One would think, then, given the widespread use of sculpture depicting religious figures, that there would exist other examples of this purportedly well-understood representation, that of horns in place of a halo.

But, it appears that we see just Moses with horns. Odd, that. No Mary with horns. One might get the impression that Jerome's erroneous translation pertaining specifically to Moses had something to with it, mightn't one?

Yes, Jerome used “horned” intentionally and specifically to describe Moses and so we depict Moses with horns and not with halo.
