And, if one is to venture into more speculative and subjective arguments, I find it rather hard to think of any lyric poet except Euripides who could have written the Adrasteia chorus or the lines about the Nightingale in the Watchers' Song; of any playwright except Euripides who would have ended a play of gallant martial adventure with the vision of a solitary mother clasping her dead son. There are many other passages, too, like the mysterious sobbing in the dark that heralds the entry of the wounded Thracian, and the final passing out of the army to its certain defeat, which seem to me more like undeveloped genius than common imitative mediocrity. If a nameless fourth-century poet wrote this play, I think we should have heard more of him.
The story of the play is taken straight from the Doloneia, an Epic rhapsody which now takes its place as the Tenth Book of the Iliad, but was very likely independent in the time of Euripides (Rise of the Greek Epic, p. 313 f.). The play seems in one or two points to follow a more archaic model than the version in our Homer. (See notes on l. 150 and l. 175.)
In Rhesus himself—the name is said to be the Thracian form of rex[1]—we seem to have the traditional divine king of the Thracian tribes about Pangaion, seen through the eyes of Greek romance. He is the son of the greatest of Rivers and the Muse of the Mountain: she is simply "The Muse," otherwise nameless, and we are lost if we try to bind her down to the identity of any Greek goddess. Like many Thracian heroes Rhesus has a dash of the Sun-god in him, the burning targe, the white horses and the splendour. Like them he is a boaster and a deep drinker, a child of battle and of song. Like other divine kings he dies in his youth and strength, and keeps watch over his people from some "feasting presence, full of light," where he lies among the buried silver-veins of Pangaion. If the uttermost need comes, doubtless he will wake again. When the Athenians began making their dangerous settlements on the coast of Thrace—ten thousand settlers were massacred by Rhesus's people about 465 B.C.: Amphipolis not fully established till 437—they found the legend of Rhesus in the air, and eventually they thought it prudent to send for his hallowed bones from the Troad, where they were supposed to be buried, and give them a tomb in the Athenian colony. Possibly that pacified him. And his legend in the mouth of the poets seemed perhaps like the story of his own mountaineers, multitudes of strong men, stormy and chivalrous, terrible in onset, who somehow in the end melted away before the skill and persistent courage of a civilised Greek city.
