Artaxerxes was the successor and brother (the
cousin-german) of the great Sapor, and the guardian of his
son Sapor III. (Agathias, 1. iv. [c. 26] p. 136, edit.
Louvre [p. 263, ed. Bonn.]). See the Universal History, vol.
xi. p. 86, 161. The authors of that unequal work have
compiled the Sassanian dynasty with erudition and diligence
but it is a preposterous arrangement to divide the Roman and
Oriental accounts into two distinct histories.
