After this he had many perilous adventures; he fought with giants and lions; he entered an enchanted castle and escaped; he went to a well in the forest, and, striking three times on a cymbal with a hammer hung there for the purpose, called forth a great giant, whom he slew, afterwards marrying his daughter. Then he went to rescue the queen of the realm, Gwenivere, from captivity. In order to reach the fortress where she was prisoner, he had to ride in a cart with a dwarf; to follow a wheel that rolled before him to show him the way, or a ball that took the place of the wheel; he had to walk on his hands and knees across a bridge made of a drawn sword; he suffered greatly. At last he rescued the queen, and later than this he married Elaine, the daughter of King Pelles, and her father gave to them the castle of Blyaunt in the Joyous Island, enclosed in iron, and with a deep water all around it. There Lancelot challenged all knights to come and contend with him, and he jousted with more than five hundred, overcoming them all, yet killing none, and at last he returned to Camelot, the place of King Arthur's court. One day he was called from the court to an abbey, where three nuns brought to him a beautiful boy of fifteen, asking that he might be made a knight. This was Sir Lancelot's own son, Galahad, whom he had never seen, and did not yet know. That evening Sir Lancelot remained at the abbey with the boy, that he might keep his vigil there, and on the morrow's dawn he was made a knight. Sir Lancelot put on one of his spurs, and Bors, Lancelot's cousin, the other, and then Sir Lancelot said to the boy, "Fair son, attend me to the court of the king;" but the abbess said, "Sir, not now, but we will send him when it shall be time." On Whitsunday, at the time called "underne," which was nine in the morning, King Arthur and his knights sat at the Round Table, where on every seat there was written, in letters of gold, the name of a knight with "here ought to sit he," or "he ought to sit here;" and thus went the inscriptions until they came to one seat (or _siège_ in French) called the "Siege Perilous," where they found newly written letters of gold, saying that this seat could not be occupied until four hundred and fifty years after the death of Christ; and that was this very day. Then there came news of a marvellous stone which had been seen above the water, with a sword sticking in it bearing the letters, "Never shall man take me hence, but only he by whose side I ought to hang, and he shall be the best knight of the world." Then two of the knights tried to draw the sword and failed to draw it, and Sir Lancelot, who was thought the best knight in all the world, refused to attempt it. Then they went back to their seats around the table.
