"This is truly a marvelous contrivance!" exclaimed Amael. "And are the names of the men known who fashioned these prodigies around us, these magnificent paintings, that gold table where a whole city is reproduced in relief, this organ, this clock, in short, all these marvels! Surely their authors must have been glorified!"

"By Bacchus, Amael, your question is droll," answered Octave smiling. "Who cares for the names of the obscure slaves who have produced these articles?"

"But the names of Clovis, of Brunhild, of Clotaire, of Charles Martel will survive the ages!" murmured the centenarian bitterly to himself, while the young Roman remarked to Vortigern:

"Let us hurry; the Emperor is waiting for us. It will take whole days, months and years to admire in detail the treasures that this palace is full of. It is the favorite resort of the Emperor. And yet, as much as his residence at Aix-la-Chapelle, he loves his old castle of Heristal, the cradle of his mighty stock of mayors of the palace, where he has heaped miracles of art."

CHAPTER IV.

CHARLEMAGNE.

Following their guide, the two hostages left the sumptuous and vast galleries, and ascended, closely behind Octave, a spiral staircase that led to the private apartment of the Emperor, the apartment around which wound the balcony that served as observatory to Charles. Two richly dressed chamberlains stood in the outer vestibule. "Stay for me here," Octave said to the Bretons; "I shall notify the Emperor that you await his pleasure, and learn whether he wishes to receive you at this moment."

Despite his race and family hatred for the Frankish Kings or Emperors, the conquerors and oppressors of Gaul, Vortigern experienced a thrill of emotion at the thought of finding himself face to face with the mighty Charles, the sovereign of almost all Europe. This first emotion was speedily joined by a second—that mighty Emperor was the father of Thetralde, the entrancing maid, who, the evening before, had thrown her bouquet to the youth. Vortigern's thoughts never a moment fell upon the brunette Hildrude. An instant later Octave reappeared and beckoned to Amael and his grandson to step in, while in an undertone he warned them: "Crook your knees low before the Emperor; it is the custom."

The centenarian cast a look at Vortigern with a negative sign of the head. The youth understood, and the Bretons stepped into the bed-chamber of Charles, whom they found in the company of his favorite Eginhard, the archchaplain whom Imma had one night bravely carried on her back. A servitor of the imperial chamber awaited the orders of his master.

When the two hostages entered the room, the monarch, whose stature, though now unarmed, preserved its colossal dimensions, was seated on the edge of his couch clad only in a shirt and hose that set off the pre-eminence of his paunch. He had just put on one shoe and held the other in his hand. His hair was almost white, his eyes were large and sparkling, his nose was long, his neck short and thick like a bull's. His physiognomy, of an open cast and instinct with joviality, recalled the features of his grandfather, Charles Martel. At the sight of the two Bretons the Emperor rose from the edge of the couch, and keeping his one shoe in his hand, took two steps forward, limping on his left foot. As he thus approached Amael he seemed a prey to a concealed emotion somewhat mingled with a lively curiosity.
