Perseus by Charles Kingsley

Fifteen years were past and gone, and the babe was now grown to be a tall lad and a sailor, and went many voyages after merchandise to the islands round. His mother called him Perseus; but all the people in Seriphos said that he was not the son of mortal man, and called him the son of Zeus, the king of the Immortals. For though he was but fifteen, he was taller by a head than any man in the island; and he was the most skilful of all in running and wrestling and boxing, and in throwing the quoit and the javelin, and in rowing with the oar, and in playing on the harp, and in all which befits a man. And he was brave and truthful, gentle and courteous, for good old Dictys had trained him well; and well it was for Perseus that he had done so. For now Danae and her son fell into great danger, and Perseus had need of all his wit to defend his mother and himself.

I said that Dictys' brother was Polydectes, king of the island. He was not a righteous man, like Dictys; but greedy, and cunning, and cruel. And when he saw fair Danae, he wanted to marry her. But she would not; for she did not love him, and cared for no one but her boy, and her boy's father, whom she never hoped to see again. At last Polydectes became furious; and while Perseus was away at sea he took poor Danae away from Dictys, saying, 'If you will not be my wife, you shall be my slave. ' So Danae was made a slave, and had to fetch water from the well, and grind in the mill, and perhaps was beaten, and wore a heavy chain, because she would not marry that cruel king. But Perseus was far away over the seas in the isle of Samos, little thinking how his mother was languishing in grief.
