Talk:The Poetry of Gaius Valerius Catullus/70

I believe it is saying that she [Lesbia/Caludia] would not prefer to be married to anyone over Catullus. That is why he says "what a woman says to her passionate lover, ought to be written on the wind and swift-flowing water." He is saying that she is lying in a contemptuous way.

To marry for men in latin is not simply "ducere" but "uxorem ducere"

Petat is not a potential subjuntive: potential subjuctive is an indipented subjuctive, that we find in main clauses; here we are in a dependant clause, an hypotetical one, and the present subjunctive express possibility (not irreality, in that case we would find the imperfect) in the present.
