Jupiter was troubled at beholding the sufferings of his mistress, and calling Mercury told him to go and despatch Argus. Mercury made haste, put his winged slippers on his feet, and cap on his head, took his sleep-producing wand, and leaped down from the heavenly towers to the earth. There he laid aside his wings, and kept only his wand, with which he presented himself as a shepherd driving his flock. As he strolled on he blew upon his pipes. These were what are called the Syrinx or Pandean pipes. Argus listened with delight, for he had never seen the instrument before. “Young man,” said he, “come and take a seat by me on this stone. There is no better place for your flocks to graze in than hereabouts, and here is a pleasant shade such as shepherds love.” Mercury sat down, talked, and told stories till it grew late, and played upon his pipes his most soothing strains, hoping to lull the watchful eyes to sleep, but all in vain; for Argus still contrived to keep some of his eyes open though he shut the rest.
Among other stories, Mercury told him how the instrument on which he played was invented. “There was a certain nymph, whose name was Syrinx, who was much beloved by the satyrs and spirits of the wood; but she would have none of them, but was a faithful worshipper of Diana, and followed the chase. You would have thought it was Diana herself, had you seen her in her hunting dress, only that her bow was of horn and Diana’s of silver. One day, as she was returning from the chase, Pan met her, told her just this, and added more of the same sort. She ran away, without stopping to hear his compliments, and he pursued till she came to the bank of the river, where he overtook her, and she had only time to call for help on her friends the water nymphs. They heard and consented. Pan threw his arms around what he supposed to be the form of the nymph, and found he embraced only a tuft of reeds! As he breathed a sigh, the air sounded through the reeds, and produced a plaintive melody. The god, charmed with the novelty and with the sweetness of the music, said, ‘Thus, then, at least, you shall be mine.’ And he took some of the reeds, and placing them together, of unequal lengths, side by side, made an instrument which he called Syrinx, in honor of the nymph.” Before Mercury had finished his story he saw Argus’s eyes all asleep. As his head nodded forward on his breast, Mercury with one stroke cut his neck through, and tumbled his head down the rocks. O hapless Argus! the light of your hundred eyes is quenched at once! Juno took them and put them as ornaments on the tail of her peacock, where they remain to this day.
