Did you know?
"Boniface" has been the name of eight popes, one antipope, and one saint, but none of those had anything (directly) to do with the English word "boniface." The word "boniface" comes from the name of the jovial innkeeper in George Farquhar's 1707 play "The Beaux' Strategem," the story of two penniless rakes who determine that one of them must find and marry a wealthy lady. Farquhar's play made more than one contribution to the English language. The name of the character of Lady Bountiful is a byword for a generous (and often conspicuously so) philanthropist. Farquhar, incidentally, never got to see the influence his play had on the lexicon. He finished "The Beaux' Strategem" on his deathbed, and died on the night of its third performance.
