But when people happened to catch a glimpse of their glittering brightness, aloft in the air, they seldom stopped to gaze, but ran and hid themselves as speedily as they could. You will think, perhaps, that they were afraid of being stung by the serpents that served the Gorgons instead of hair,--or of having their heads bitten off by their ugly tusks,--or of being torn all to pieces by their brazen claws. Well, to be sure, these were some of the dangers, but by no means the greatest, nor the most difficult to avoid. For the worst thing about these abominable Gorgons was, that, if once a poor mortal fixed his eyes full upon one of their faces, he was certain, that very instant, to be changed from warm flesh and blood into cold and lifeless stone! Thus, as you will easily perceive, it was a very dangerous adventure that the wicked King Polydectes had contrived for this innocent young man. Perseus himself, when he had thought over the matter, could not help seeing that he had very little chance of coming safely through it, and that he was far more likely to become a stone image than to bring back the head of Medusa with the snaky locks. For, not to speak of other difficulties, there was one which it would have puzzled an older man than Perseus to get over. Not only must he fight with and slay this golden-winged, iron-scaled, long-tusked, brazen-clawed, snaky-haired monster, but he must do it with his eyes shut, or, at least, without so much as a glance at the enemy with whom he was contending. Else, while his arm was lifted to strike, he would stiffen into stone, and stand with that uplifted arm for centuries, until time, and the wind and weather, should crumble him quite away. This would be a very sad thing to befall a young mail who wanted to perform a great many brave deeds, and to enjoy a great deal of happiness, in this bright and beautiful world. So disconsolate did these thoughts make him, that Perseus could not bear to tell his another what he had undertaken to do. He therefore took his shield, girded on his sword, and crossed over from the island to the mainland, where he sat down in a solitary place, and hardly refrained from shedding tears. But, while he was in this sorrowful mood, he heard a voice close beside him. “Perseus,” said the voice, “why are you sad?”
