I found this site with many latin proverbs, in which some of you might be interested by what I read form later posts. Anyway, the link is http://www.hkocher.info/minha_pagina/adagia/adagia.htm, just ignore the obscure ibericval inscriptions and go directly to the letterrs at the bottom. Most of the translations are into romance tongues, like french, spanish, and many others, but we are here to read the original aren’t we? 
Now you can say proudly (?!) that your compostion are filled with commonplaces.
