Often and often, after this, did Theseus ask his mother whether it was yet time for him to go to Athens; and still his mother pointed to the rock, and told him that, for years to come, he could not be strong enough to move it. And again and again the rosy-checked and curly-headed boy would tug and strain at the huge mass of stone, striving, child as he was, to do what a giant could hardly have done without taking both of his great hands to the task. Meanwhile the rock seemed to be sinking farther and farther into the ground. The moss grew over it thicker and thicker, until at last it looked almost like a soft green seat, with only a few gray knobs of granite peeping out. The overhanging trees, also, shed their brown leaves upon it, as often as the autumn came; and at its base grew ferns and wild flowers, some of which crept quite over its surface. To all appearance, the rock was as firmly fastened as any other portion of the earth's substance. But, difficult as the matter looked, Theseus was now growing up to be such a vigorous youth, that, in his own opinion, the time would quickly come when he might hope to get the upper hand of this ponderous lump of stone. "Mother, I do believe it has started!" cried he, after one of his attempts. "The earth around it is certainly a little cracked!" "No, no, child!" his mother hastily answered. "It is not possible you can have moved it, such a boy as you still are!" Nor would she be convinced, although Theseus showed her the place where he fancied that the stem of a flower had been partly uprooted by the movement of the rock. But Aethra sighed, and looked disquieted; for, no doubt, she began to be conscious that her son was no longer a child, and that, in a little while hence, she must send him forth among the perils and troubles of the world. It was not more than a year afterwards when they were again sitting on the moss-covered stone. Aethra had once more told him the oft-repeated story of his father, and how gladly he would receive Theseus at his stately palace, and how he would present him to his courtiers and the people, and tell them that here was the heir of his dominions. The eyes of Theseus glowed with enthusiasm, and he would hardly sit still to hear his mother speak. "Dear mother Aethra," he exclaimed, "I never felt half so strong as now! I am no longer a child, nor a boy, nor a mere youth! I feel myself a man! It is now time to make one earnest trial to remove the stone." "Ah, my dearest Theseus," replied his mother "not yet! not yet!" "Yes, mother," said he, resolutely, "the time has come!"
