“Demades said that Xerxes fortified the sea with his ships, covered the land with his armies, concealed the sky with his weapons, and filled Persia with Greek prisoners. And now justly the barbarian is praised by Athenians because he took captive Greeks, but Alexander, a Greek, and leading Greeks, did not take captive those arrayed against him.[...]No one of the Greek kings went to Egypt except Alexander alone, and he went, not to make war, but to consult an oracle as to where he should found a city which would forever bear his name.[...]So Alexander was the first of the Greeks to take Egypt, and so became the first both of Greeks and of barbarians.”

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "“Demades said that Xerxes fortified the sea with his ships, covered the land with his armies, concealed the sky with his weapons, and filled Persia with Greek prisoners. And now justly the barbarian is praised by Athenians because he took captive Greeks, but Alexander, a Greek, and leading Greeks, did not take captive those arrayed against him.[...]No one of the Greek kings went to Egypt except Alexander alone, and he went, not to make war, but to consult an oracle as to where he should found a city which would forever bear his name.[...]So Alexander was the first of the Greeks to take Egypt, and so became the first both of Greeks and of barbarians.”" in the context of "Historia Alexandri Magni of Pseudo-Kallisthenes, 2.4" to mean that wisdom is timeless.
