[Footnote 30: The policy of the Greeks, revolt of Maniaces,
&c., must be collected from Cedrenus, (tom. ii. p. 757,
758,) William Appulus, (l. i. p 257, 258, l. ii. p. 259,)
and the two Chronicles of Bari, by Lupus Protospata,
(Muratori, Script. Ital. tom. v. p. 42, 43, 44,) and an
anonymous writer, (Antiquitat, Italiae Medii Aevi, tom. i. p
31 - 35.) This last is a fragment of some value.]
