Presently they came upon a twin palace with twin turrets rising high into the air; and before the twin doors the prisoners dismounted. Marvel was escorted through one door and Nerle through another, and then they saw each other going down a double hallway to a room with a double entrance.
Passing through this they found themselves in a large hall with two domes set side by side in the roof. The domes were formed of stained glass, and the walls of the hall were ornamented by pictures in pairs, each pair showing identically the same scenes. This, was, of course, reasonable enough in such a land, where two people would always look at two pictures at the same time and admire them in the same way with the same thoughts.
Beneath one of the domes stood a double throne, on which sat the Ki of Twi--a pair of gray-bearded and bald-headed men who were lean and lank and stoop-shouldered. They had small eyes, black and flashing, long hooked noses, great pointed ears, and they were smoking two pipes from which the smoke curled in exactly the same circles and clouds.
Beneath the other dome sat the Ki-Ki of Twi, also on double thrones, similar to those of the Ki. The Ki-Ki were two young men, and had golden hair combed over their brows and "banged" straight across; and their eyes were blue and mild in expression, and their cheeks pink and soft. The Ki-Ki were playing softly upon a pair of musical instruments that resembled mandolins, and they were evidently trying to learn a new piece of music, for when one Ki-Ki struck a false note the other Ki-Ki struck the same false note at the same time, and the same expression of annoyance came over the two faces at the same moment.
When the prisoners entered, the pairs of captains and soldiers bowed low to the two pairs of rulers, and the Ki exclaimed--both in the same voice of surprise:
"Great Kika-koo! what have we here?"
"Most wonderful prisoners, your Highnesses," answered the captains. "We found them at your cities' gates and brought them to you at once. They are, as your Highnesses will see, each singular, and but half of what he should be."
"'Tis so!" cried the double Ki, in loud voices, and slapping their right thighs with their right palms at the same time. "Most remarkable! Most remarkable!"
"I don't see anything remarkable about it," returned Prince Marvel, calmly. "It is you, who are not singular, but double, that seem strange and outlandish."
"Perhaps--perhaps!" said the two old men, thoughtfully. "It is what we are not accustomed to that seems to us remarkable. Eh, Ki-Ki?" they added, turning to the other rulers.
