[Footnote 30: For the origin and revolutions of the first
Turkish empire, the Chinese details are borrowed from De
Guignes (Hist. des Huns, tom. P. ii. p. 367 - 462) and
Visdelou, (Supplement a la Bibliotheque Orient. d'Herbelot,
p. 82 - 114.) The Greek or Roman hints are gathered in
Menander (p. 108 - 164) and Theophylact Simocatta, (l. vii.
c. 7, 8.)]
