Ljubljana Cathedral, Slovenia
A label below the statue says this saint was Bishop of Ljubljana ("Episcopus Æmon."). He is not in Butler, nor even in the enormous list of saints at Catholic Online. The diocese of Ljubljana (Laibach) was erected in 1461, and all bishops from 1463 to date are listed at the Wikipedia page for the diocese. No Florius is among them, nor any sainted person.
The phrase "Reži nas…" at the foot of the statue means "Deliver us…" and is of course from the Lord's Prayer.
