Orberg (Donatus?) has:
M. 'Super' quam vim habet?
['Super' has what effect / power / meaning]
D. Ubi locum significat, magis accusativo casui servit quam ablativo; ubi mentionem alicuius facimus, ablativo tantum, ut 'multa super Priamo rogitans, super Hectore multa'* (Vergilius: Aeneis I.750).
When it means [towards a] location, it is more subject to the accusative case than the ablative ['subject to dative rather than the ablative?]; when we are making mention of something, the ablative only, such as 'asking much about Priamus, much about Hector'.
