Quite differently did Æolus treat another famous hero, Ulysses, whose ships, on the long homeward journey, touched at the Lipari Islands. Here the wanderer was hospitably entertained by Æolus, and when he set sail again, the kindly god sent the west wind to blow the ships gently over the sea, while he shut up the blustering winds in a leather bag and tied it with a silver string. This bag he gave to Ulysses, "the sagacious," and bade him keep it closed until the journey was over. For nine days and nights the hero stood at the helm watching, while the west wind bore the ships along without the help of oars. At last, exhausted by his long vigil, Ulysses fell asleep; and the sailors, believing that the bag contained treasure that King Æolus had generously given, untied the string and freed the roistering winds. The ships were now driven hither and thither by the madly-rushing winds, and were tossed over the sea far away from the longed-for Ithaca. Finally they were blown back to the Lipari Islands, where Æolus received them but coldly, and refused to help them further. So they turned their prows once more toward home, and worked wearily against wind and weather by the slow pull of the oars. The Athenians built a temple to Æolus, which is still extant, and is generally known as the Tower of the Winds, or the Temple of Æolus. The structure is hexagonal, and on each side there is a flying figure of one of the winds. Notus (or Auster), the south wind, was usually represented by an old man with dusky wings. He is clad in a black robe, and his head is covered with clouds, for he sends the rains and sudden showers. Eurus, the east wind, was a young man full of impetuous and lively motion. Corus, the northwest wind, drove clouds of snow before him, and Boreas was a figure rough and shivering. Zephyrus had a lapful of flowers, and was the one wind sent to play among children. Boreas was the bringer of hail and tempests, and when he wooed the nymph Orithyia, he sought in vain to approach her gently, and to breathe his love softly. But he could not sigh, and his lightest whisper frightened the maiden by its harshness; so Boreas gave up attempting to win her by gentle means and boldly carried her off to his home in the midst of snow and ice. Their children were Zetes and Calais--winged warriors who accompanied the Argonauts on their famous expedition, and performed a valuable service in driving away the Harpies.[68] II. Janus
