I working on a literary piece and trying to find the first known use in Latin of of "pulcher" (feminine pulchra, neuter pulchrum, comparative pulchrior, superlative pulcherrimus), e.g., "first known use found in Virgil's . . . ".
I do not know Latin, nor am I at all acquainted with linguistics. If there are resources that would be accessible for a person like me (retired lawyer, in other words, I am not without reasoning capacity), I'd appreciate learning whatever you might suggest in this regard.
