[Footnote 109: The silence of the Sicilian historians, who
end too soon, or begin too late, must be supplied by Otho of
Frisingen, a German, (de Gestis Frederici I. l. i. c. 33, in
Muratori, Script. tom. vi. p. 668,) the Venetian Andrew
Dandulus, (Id. tom. xii. p. 282, 283) and the Greek writers
Cinnamus (l. iii. c. 2 - 5) and Nicetas, (in Manuel. l. iii.
c. 1 - 6.)]
