71 Diogenes Laertius (in vita Empedoclis) says that Agrigentum contained only 800,000 inhabitants.

72 The country that supplied this number was not above a third of Italy—viz., the Pope’s dominions, Tuscany, and a part of the kingdom of Naples; but perhaps in those early times there were very few slaves except in Rome, or the great cities.

73 Plutarch (in vita Cæs.) makes the number that Cæsar fought with amount only to three millions; Julian (in Cæsaribus) to two.

74 Argos seems also to have been a great city, for Lysias contents himself with saying that it did not exceed Athens. (Orat. 34.)

75 Orat. contra Verem, lib. 4, cap. 52. Strabo, lib. 6, says it was twenty-two miles in compass; but then we are to consider that it contained two harbours within it, one of which was a very large one, and might be regarded as a kind of bay.

76 Demosthenes assigns 20,000.

77 Lib. 2. Diodorus Siculus’s account perfectly agrees (lib. 12).
