[Footnote 126: The origin and progress of the title of
cardinal may be found in Themassin, (Discipline de l'Eglise,
tom. i. p. 1261 - 1298,) Muratori, (Antiquitat. Italiae
Medii Aevi, tom. vi. Dissert. lxi. p. 159 - 182,) and
Mosheim, (Institut. Hist. Eccles. p. 345 - 347,) who
accurately remarks the form and changes of the election.
The cardinal-bishops so highly exalted by Peter Damianus,
are sunk to a level with the rest of the sacred college.]
