History of Friedrich II of Prussia, Volume 02 by Thomas Carlyle

Kaiser Ludwig died in 1347, while the False Waldemar was still busy. We saw Karl IV., Johann of Bohemia's second son, come to the Kaisership thereupon, Johann's eldest Nullity being omitted. This Fourth Karl, -- other three Karls are of the Charlemagne set, Karl the Bald, the Fat, and such like, and lie under our horizon, while CHARLES FIFTH is of a still other set, and known to everybody, -- this Karl IV. is the Kaiser who discovered the Well of KARLSBAD (Bath of Karl), known to Tourists of this day; and made the GOLDEN BULL, which I forbid all Englishmen to take for an agricultural Prize Animal, the thing being far other, as is known to several.

There is little farther to be said of Karl in Reichs-History. An unesteemed creature; who strove to make his time peaceable in this world, by giving from the Holy Roman Empire with both hands to every bull-beggar, or ready-payer who applied. Sad sign what the Roman Empire had come and was coming to. The Kaiser's shield, set up aloft in the Roncalic Plain in Barbarossa's time, intimated, and in earnest too, "Ho, every one that has suffered wrong! " -- intimates now, "Ho, every one that can bully me, or has money in his pocket! " Unadmiring posterity has confirmed the nickname of this Karl IV.; and calls him PFAFFEN-KAISER. He kept mainly at Prag, ready for receipt of cash, and holding well out of harm's way. In younger years he had been much about the French Court; in Italy he had suffered troubles, almost assassinations; much blown to and fro, poor light wretch, on the chaotic Winds of his Time, -- steering towards no star.
