Note 085
The expedition of Heraclius into Persia is finely illustrated by M. D'Anville, (Memoires de l'Academie des Inscriptions, tom. xxviii. p. 559 - 573.) He discovers the situation of Gandzaca, Thebarma, Dastagerd, &c., with admirable skill and learning; but the obscure campaign of 624 he passes over in silence.]
