While shopping for Gold online, I've come across this coin which is engraved with the following writings:
ens causa sui and
ex unitae vires
Now, you would think a quick online search would return a mostly direct translation of
ens causa sui but it appears there are many ever so slightly different interpretations of the meanings which has yet to give me the certainty of what it really means.
This is the coin from the movie John Wick. Perhaps this could add more context to it?
