Thus Ulysses disobeys Circe's command not to attempt to fight Scylla with weapons; the reason of her injunction becomes plain. Not a sensuous thing to be slain is Scylla, in spite of her animal figure; the poet hints that she is to be encountered by mind, which must here see both sides at once and so assert its supremacy over both. To be intent upon the one and disregard the other--that is the grand human danger. Hence the thought of Scylla and Charybdis has passed into the literature of the world, nay into the proverbs of the people, to express the peril of one-sidedness, as well as the inherent dualism in all conduct. Moreover the golden mean is suggested, that principle of action so familiar in later Greek philosophy. Deeper than this golden mean, however, runs the idea here; the dialectic of existence, the twofoldness which must be made one, the higher synthesis over all analysis are dimly intimated in the marvelous tale. 3. Having escaped through the two rocks, Ulysses and his companions come to "the flawless island of the Sun," the all-seeing luminary of Heaven. It is the total light beholding the totality. Is it not manifest that we have passed out of dualism into unity, out of strife into harmony? The island is represented as pastoral, peaceful, idyllic, with its herds reposing in sunlight; certainly a decided contrast to the noise and struggle in the region of Scylla and Charybdis. Or we may give the matter a psychological turn and say: Such is the transition from the Understanding with its finitude to Reason with its universality, to the all-seeing light within. Ulysses, having transcended the limit he showed in his last experience, has gone forward to the clear sunlit realm which illumines all limitations. But just at this point danger arises. On the island are pasturing herds of oxen and sheep sacred to the Sun, things of light consecrated to light. The temptation will be to use them for the gratification of appetite, perhaps under some strong stress. Already both Tiresias and Circe have given the warning, which Ulysses now repeats to his companions and even exacts an oath from them not to harm the holy flocks. But hunger pinches, Ulysses again goes to sleep at the wrong moment, and the oxen of the Sun are slain by his men. It is true that the test is a hard one, death by starvation is impending, and they yield, not only violating their oaths but their light. Then they defiantly repeated their deed, "for six whole days they feasted, selecting the best of the Sun's oxen." When Ulysses awoke, he chid them sternly, but did not, or could not, stop them. The result was, they perished.
