: What is the origin of the phrase "let bygones be bygones"?
It is easy to imagine someone saying this in the same meaning as "Let sleeping dogs lie," or "Let past things remain in the past." The first citation of the phrase in the Oxford English Dictionary dates from 1638.
"1636 RUTHERFORD Lett. lxii. I. 166 Pray..that byegones betwixt me and my Lord may be byegones. . . ."
Another interesting citation in their list is that of Lord Chesterfield,
"1758 CHESTERFIELD Lett. IV. 147 By-gones are by-gones, as Chartres, when he was dying, said of his sins."
I don't know which Chartres may have said this. There are a fair number of invidivuals having this name, but my short survey has not revealed who may have said this on his death-bed.
