They sang like nightingales among the thickets, and Perseus stopped to hear their song; but the words which they spoke he could not understand; no, nor no man after him for many a hundred years. So he stepped forward and saw them dancing, hand in hand around the charmed tree, which bent under its golden fruit; and round the tree-foot was coiled the dragon, old Ladon the sleepless snake, who lies there for ever, listening to the song of the maidens, blinking and watching with dry bright eyes.
Then Perseus stopped, not because he feared the dragon, but because he was bashful before those fair maids; but when they saw him, they too stopped, and called to him with trembling voices -'Who are you? Are you Heracles the mighty, who will come to rob our garden, and carry off our golden fruit?' And he answered -'I am not Heracles the mighty, and I want none of your golden fruit. Tell me, fair Nymphs, the way which leads to the Gorgon, that I may go on my way and slay her.'
'Not yet, not yet, fair boy; come dance with us around the tree in the garden which knows no winter, the home of the south wind and the sun. Come hither and play with us awhile;we have danced alone here for a thousand years, and our hearts are weary with longing for a playfellow. So come, come, come!'
'I cannot dance with you, fair maidens; for I must do the errand of the Immortals. So tell me the way to the Gorgon, lest I wander and perish in the waves.'
Then they sighed and wept; and answered - 'The Gorgon! she will freeze you into stone.'
'It is better to die like a hero than to live like an ox in a stall. The Immortals have lent me weapons, and they will give me wit to use them.'
Then they sighed again and answered, 'Fair boy, if you are bent on your own ruin, be it so. We know not the way to the Gorgon; but we will ask the giant Atlas, above upon the mountain peak, the brother of our father, the silver Evening Star. He sits aloft and sees across the ocean, and far away into the Unshapen Land.'
So they went up the mountain to Atlas their uncle, and Perseus went up with them. And they found the giant kneeling, as he held the heavens and the earth apart.
They asked him, and he answered mildly, pointing to the sea-board with his mighty hand, 'I can see the Gorgons lying on an island far away, but this youth can never come near them, unless he has the hat of darkness, which whosoever wears cannot be seen.'
Then cried Perseus, 'Where is that hat, that I may find it?'
But the giant smiled. 'No living mortal can find that hat, for it lies in the depths of Hades, in the regions of the dead. But my nieces are immortal, and they shall fetch it for you, if you will promise me one thing and keep your faith.'
Then Perseus promised; and the giant said, 'When you come back with the head of Medusa, you shall show me the beautiful horror, that I may lose my feeling and my breathing, and become a stone for ever; for it is weary labour for me to hold the heavens and the earth apart.'
Then Perseus promised, and the eldest of the Nymphs went down, and into a dark cavern among the cliffs, out of which came smoke and thunder, for it was one of the mouths of Hell.
And Perseus and the Nymphs sat down seven days, and waited trembling, till the Nymph came up again; and her face was pale, and her eyes dazzled with the light, for she had been long in the dreary darkness; but in her hand was the magic hat.
Then all the Nymphs kissed Perseus, and wept over him a long while; but he was only impatient to be gone. And at last they put the hat upon his head, and he vanished out of their sight.
