On... Friendship and Titles

[amans]

I've been browsing around and noticed that both Cicero and Seneca wrote a treatise de amicitia. I am, however, not sure the latter survives, but I thought it was interesting. Does anyone know of other works with this title (or equivalents in Greek: [face=spionic]peri/ fili/aj[/face] perhaps?) - or of other examples of two or more works with exactly the same title? mihi uidetur that the Romans and the Greeks often used de and [face=spionic]peri/[/face] in their titles. Why? bonum diem habete, amici

Well, I don't think there are any other ways to say "about friendship" or "concerning friendship" or "on friendship" better than using "de". "de" is still used today in Portuguese for that same very meaning.

bonum diem habete, amici

tu quoque!
