In much the same sense is the frequent reference to the Eumenides. We have to picture in the first instance no doubt these avenging maidens as Furies, who pursue the transgressor in an external form. But this pursuit is but another aspect of the Fury which drives through the soul of the perpetrator of crime; and Sophocles in the Œdipus Colonus (I. 1434) actually refers to them in this sense of inward spiritual forces, as the Eumenides of Œdipus himself, that is to say, who signify the father's curse as the result of the stress of emotion caused by the conduct of his sons. We have, then, and equally have not reason on our side whether we identify the gods with powers external to man, or find in them that which belongs exclusively to his spiritual life. They are in fact both. In Homer, for example, the activity of gods and men is a constantly involved skein[347]. The gods appear to accomplish what is foreign to human activity, and yet for all that execute only that which is in vital co-ordination with his own emotional life. In the "Iliad," for example, when Achilles, in the stress of controversy, is about to raise his sword against Agamemnon, Athene steps forth behind him and takes hold of his head of flaxen hair, visible only to himself. Hero, who is equally anxious over Achilles and Agamemnon, sends for them from Olympus, and their admission there appears to be wholly independent of the desire of Achilles. On the other hand we have no difficulty in seeing that the sudden appearance of Athene, the wisdom which puts constraint upon the hero's wrath, is simply a reflection of internal conflict, that the entire description but states in imaginative form what was experienced in the heart of our hero. In fact Homer himself points this out a few verses previously ("Iliad," I, v, 190), when he relates about the debate that took place in his heart in the following terms: ἢ ὅγε φάσγανον ὀξὺ ἐρυσσάμενος παρὰ μηροῦ τοὺς μὲν ἀναστήσειεν, ὃ δ᾽ Ἀτρέιδην ἐναρίξοι, ἡὲ χόλον πάυσειεν ἐρητύσείε τε θυμὀν.[348]
