For the African war see Procopius (de Bell.Vandal. 1. i. c. 6, p. 19l, 192, 193 [tom. i. p. 335, sqq., ed bonn]), Theophanes (p. 99, 100, 101, [ed. Par.; tom. i. p. 179 sqq., ed. Bonn]), Cedrenus (p. 349, 350 [tom. i. p. 613, ed. Bonn]), and Zonaras (tom. ii. 1. xiv. p. 50, 51). Montesquieu (Considerations sur la Grandeur, etc., c. xx. tom. iii. p. 497) has made a judicious observation on the failure of these great naval armaments.
