For the whole of my life until I found out from a BBC4 program I was watching recently, I was convinced that Ovid got himself into trouble for (amongst other indiscretions) for the work "Ars Amandi" which I think would be the gerund. Turns out the work was called "Ars amatoria". Where did I get the wrong title from?
Think some of Catullus' poems were one of my A-Level set books. "odi et amo...", and "women's promises are writ in water" (though memory of that doesn't stretch further than "mulieres")
A funny story re Catullus. Most of the texts were published in Victorian times and reprinted. Asterisks abounded. When asked the reason for asterisks there were two stock replies:
1. It possesses no artistic merit
2. It is a lost fragment.
One day we were reading ode 58 in which Catullus bemoans the loss of his love, Lesbia. The last two lines were starred out. I was not satisfied with the above explanations so went to the local Lit. and Phil. library who kept a range of classical works. There I found the last two lines; they were obscene. You should have seen my Latin master's face the next day when I supplied them.
