Herodotus elegantly describes the strange effects of grief in another royal captive, Psammetichus of Egypt, who wept at the lesser and was silent at the greatest of his calamities, (l. iii. c. 14.) In the interview of Paulus Aemilius and Perses, Belisarius might study his part; but it is probable that he never read either Livy or Plutarch; and it is certain that his generosity did not need a tutor.
