When Orlando awoke, his indignation, as may be supposed, was great on the discovery of the theft; but, like a good knight and true, he was not to be diverted from his enterprise. He tore off a huge branch of an elm to supply the place of his sword; and, as the sun rose, took his way towards the gate of the garden, where a dragon was on his watch. This he slew by repeated blows, and entered the garden, the gate of which closed behind him, barring retreat. Looking round him, he saw a fair fountain, which overflowed into a river, and in the centre of the fountain a figure, on whose forehead was written: "The stream which waters violet and rose, From hence to the enchanted palace goes." Following the banks of this flowing stream, and rapt in the delights of the charming garden, Orlando arrived at the palace, and entering it, found the mistress, clad in white, with a crown of gold upon her head, in the act of viewing herself in the surface of the magic sword. Orlando surprised her before she could escape, deprived her of the weapon, and holding her fast by her long hair, which floated behind, threatened her with immediate death if she did not yield up her prisoners, and afford him the means of egress. She, however, was firm of purpose, making no reply, and Orlando, unable to move her either by threats or entreaties, was under the necessity of binding her to a beech, and pursuing his quest as he best might. He then bethought him of his book, and, consulting it, found that there was an outlet to the south, but that to reach it a lake was to be passed, inhabited by a siren, whose song was so entrancing as to be quite irresistible to whoever heard it; but his book instructed him how to protect himself against this danger. According to its directions, while pursuing his path, he gathered abundance of flowers, which sprung all around, and filled his helmet and his ears with them; then listened if he heard the birds sing. Finding that, though he saw the gaping beak, the swelling throat, and ruffled plumes, he could not catch a note, he felt satisfied with his defence, and advanced toward the lake. It was small but deep, and so clear and tranquil that the eye could penetrate to the bottom. He had no, sooner arrived upon the banks than the waters were seen to gurgle, and the siren, rising midway out of the pool, sung so sweetly that birds and beasts came trooping to the water-side to listen. Of this Orlando heard nothing, but, feigning to yield to the charm, sank down upon the bank. The siren issued from the water with the intent to accomplish his destruction. Orlando seized her by the hair, and while she sang yet louder (song being her only defence) cut off her head. Then, following the directions of the book, he stained himself all over with her blood.
