The problem is that the Petronius/Eunice love theme isn't Rozsa's OWN! His arrangements are there, but the tune is, as we know, an Ode of Pindar, authentically BC Greek. So we can't claim it as HIS strictly. Petronius' OWN theme, a folktune-like melody is melancholy and reflective, but this is not a 'love theme' as such.

P.S. This looks like an interesting little item , but there are no soundfiles: the CD contains at least two 'Quo Vadis?' source pieces, the 'Hymn to Nemesis' and the Helios hymn:

Better still, here's a CD sample site that has the 'Hymn to Nemesis' (as in Finale) the Hymn 'au Soleil' (as in Gratus' march and the Burning of Rome) and the Eunice theme (sample 14) named as a Pythian Ode:

By far the most interesting thing about the Eunice theme is its age and authenticity. But to say Rozsa wrote it is going too far. If you listen to track 14 you'll see that the WHOLE theme was ENTIRELY there two millenia ago: Rozsa didn't need to extend, vary or develop it ... Greek tunes were long and complex. 'Fragments' may have survived, but fragmentary they are not. We may only credit him with the taste to select and arrange it.
