The policy of the Greeks, revolt of Maniaces, etc., 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.
