Latin was the language of the Roman Empire and of diplomacy for much of Europe well into the 16th century. This language appears unique to most modern language speakers because of its relative independence from word order and terse, yet rich sentences. Romans, especially those whose material has survived the march of time, were generally well off and affluent – so most of the proverbs will reflect this in their content and perspective.
Nihil tam munitum quod non expugnari pecunia possit. (Nothing is so fortified that it can’t be conquered with money.)
Semper inops quicumque cupit. (Whoever desires is always poor)
