The Artsy Honker

"A text in Latin shall be used", I read, of a choral composition competition.

It turns out they are a bit more picky than that:

Only texts by the following Latin Authors will be accepted: Ovidio (Publius Ovidius Naso), Orazio (Quintus Horatius Flaccus), Virgilio (Publius Vergilius Maro), Catullo (Gaius Valerius Catullus), Marziale (Marcus Valerius Martialis), Lucrezio (Titus Lucretius Carus).

Being more a Christian sacred composer than anything else, and lacking a Classics background, I'm utterly unfamiliar with most of these. I understand Catullus is rather rude.

I suspect the pronunciation varies considerably from church Latin, too, though probably not so much that I can't set it well.

I feel a bit like this is a veiled attempt to filter out people who aren't posh enough, or haven't had the "right" educational background. I dislike those kinds of barriers to participation.

So: does anyone have any suggestions for me from those authors? Any passages you'd particularly like to hear me set to music?
