I don't think it is Rosa arvensis. I cannot see any sign of united stigmas and the leaflets look wrong. British roses are hard enough!
I show the column of united stigmas. The leaflets seem a bit variable.
I found a picture taken at the same time which I had missed as it was key worded for the Coleoptera. Styles definitely connate in a column. In Italy there are only three possible species. R. sempervirens has evergreen leaves which this does not. So we only need to consider if it is R. stylosa. The couplet 5 in Stace 3 p. 268 says
5 Style as long as the stamens; top of hypanthium flat; inner sepals entire, outer with very few lobes ..... R. arvensis
5 Style shorter than stamens; top of hypanthium conical; sepals pinnately lobed .... R. stylosa
