When the door of her room was opened Cassiopeia never stirred. Andromeda’s arms were around her, Andromeda’s kisses were on her cheek before she could believe that her daughter was in very truth alive. Then, indeed, the mother’s joy was boundless. So fair, so good was the maiden that Perseus loved her, and thanked the gods who had led him to that desolate land. Before many weeks had passed the princess was wedded to the stranger who had saved her from the terrible sea-monster. Twelve months later they left Cassiopeia, and sailed away to Seriphus, for Perseus longed to see his mother, and to bring to her his beautiful bride. Seven long years had passed since Perseus set out on his quest, and Danae’s heart was glad when she saw her son once more. As soon as their greetings were over, Perseus left Andromeda with his mother, and went to the palace, carrying with him the head of Medusa in the magic bag. The king was feasting with his nobles when Perseus entered the banqueting-hall. Long, long ago he had ceased to think of Perseus, for he believed that he had perished on his wild adventure. Now he saw him, grown to be a man, entering the hall, and he grew pale with sudden fear. Paying no heed to any, Perseus strode through the throng of merry courtiers until he stood before the throne on which sat Polydectes. ‘Behold the gift I promised you seven years ago, O King!’ cried Perseus, and as he spoke he drew forth the head of Medusa and held it up for the king to see. Polydectes and his startled nobles stared in horror at the awful face of the Gorgon, and as they gazed the king and all his followers were changed into figures of stone. Then Perseus turned and left the palace, and telling the island folk that Polydectes was dead, he bade them now place Dictys, the fisherman, upon the throne. He then hastened to the temple of Athene, and with a glad heart gave back to the goddess the gifts which had served him so well--the helmet, the sandals, the shield. As his own offering to Athene he gave the head of the Gorgon. She, well pleased, accepted it, and had it placed in the centre of her shield, so from that day the Ægis became more terrible than before, for the Gorgon’s head still turned to stone whoever looked upon it. Danae had often talked to Perseus when he was a boy of Acrisius, her father, and of Argos, the city from which he had been banished when he was a babe. Perseus now resolved to sail to Argos with Danae and Andromeda. During these years Acrisius had been driven from his throne by an ambitious prince. He was in a miserable dungeon, thinking, it may be, of his unkindness to his daughter Danae, when she once again reached Argos. Perseus soon drove away the usurper, and for his mother’s dear sake he took Acrisius out of his dungeon and gave him back his kingdom. For Danae had wept and begged Perseus to rescue his grandfather from prison.
