“ Various were the explanations of this prodigy given by the soothsayers; but Aristander, [5] a man of Telmissus, a soothsayer, bade Alexander take courage; for he said it was evident from this that there would be much labour for the epic and lyric poets, and for the writers of odes, to compose and sing about Alexander and his achievements.
(B.C. 334.) At the beginning of the spring he marched towards the Hellespont, entrusting the affairs of Macedonia and Greece to Antipater. He led not much above 30,000 infantry together with light-armed troops and archers, and more than 5,000 cavalry. ”

“ A report also prevails that he offered sacrifice to Priam upon the altar of Zeus the household god, deprecating the wrath of Priam against the progeny of Neoptolemus, from whom Alexander himself derived his origin.
↑ Archelaus was king of Macedonia from B.C. 413-399. He improved the internal arrangements of his kingdom, and patronised art and literature. He induced the tragic poets, Euripides and Agathon, as well as the epic poet Choerilus, to visit him; and treated Euripides especially with favour. He also invited Socrates, who declined the invitation. ”

“ When he came to Elaēus he offered sacrifice to Protesilaus upon the tomb of that hero, both for other reasons and because Protesilaus seemed to have been the first of the Greeks who took part with Agamemnon in the expedition to Ilium to disembark in Asia. ”
