Thomas Carlyle, History of Friedrich II of Prussia…
“ SEVEN IN NUMBER. 1. Triple Alliance, English, Dutch, French (4th January, 1717) , saying, "Peace, then! No Alberoni-plotting; no Duel-fighting permitted!" Same Powers, next year, proposing Terms of Agreement; Kaiser gloomily accepting them; which makes it Quadruple Alliance (18th July, 1718) ”
