The story of the word

It is a perfect tense, so the sense is not I find but I have found and the finding is done. Vitruvius tells the bath story about Archimedes two centuries after the fact, and no contemporary source mentions it, which is roughly the evidential standing of Newton's apple. California put the word on its state seal in 1849, meaning the gold, and it is still the state motto.
