For these wars of the Turks and Romans, see in general the Byzantine histories of Zonaras and Cedrenus, Scylitzes the continuator of Cedrenus, and Nicephorus Bryennius Caesar. The two first of these were monks, the two latter statesmen; yet such were the Greeks, that the difference of style and character is scarcely discernible. For the Orientals, I draw as usual on the wealth of D'Herbelot (see titles of the first Seljukides) and the accuracy of De Guignes (Hist. des Huns, tom. iii. l. x.).
