> It has been exceptionally well preserved because it was reused as a Roman-era paving stone on a colonnaded street
The sculpture is very 3-dimensional. I don't get how it made a good paving stone, or how being used as a paving stone didn't end up conflicting with the "well preserved" part more.
> The statue was discovered in two parts
So maybe it was about one of those parts and the lower one looks like it could be a decent paving stone.
