Engaged at the other end of the chamber, Amael did not overhear the words of Octave that were turning Vortigern's face as scarlet as the color of his chaperon's cloak. The preparations for the presentation being concluded, the two hostages followed their guide to appear before the Emperor. After crossing an infinite number of passages and mounting and descending an equal number of stairs, in all of which they encountered more women than men, the number of women lodged in the Imperial Palace being prodigious, the Bretons were led through vast halls. To describe the sumptuous magnificence of these galleries would be no less impossible than to enumerate the pictures with which their halls were ornamented. Artisans, brought from Constantinople, where, at the time, the school of Byzantine painting flourished, had covered the walls with gigantic designs. In one place the conquests of Cyrus over the Persians were displayed; at another, the atrocities of the tyrant Phalaris, witnessing the agonies of his victims, who were led to be burned alive in a brass caldron red with heat; at still another place, the founding of Rome by Romulus and Remus was reproduced; the conquests of Alexander and Hannibal, and many other heroic subjects. One of the galleries of the palace was consecrated wholly to the battles of Charles Martel. He was seen triumphing over Saxons and Arabs, who, chained at his feet, implored his clemency. So striking was the resemblance that while crossing the hall Amael cried out: "It is he! Those are his features! That was his bearing! He lives again! It is Charles!" "One would think you recognize an old acquaintance," observed the young Roman, smiling. "Are you renewing your acquaintance with Charles Martel?" "Octave," answered the old man melancholically, "I am one hundred years old--I fought at the battle of Poitiers against the Arabs." "Among the troops of Charles Martel?" "I saved his life," answered Amael, contemplating the gigantic picture; and speaking to himself, he proceeded with a sigh: "Oh, how many recollections, sweet and sad, do not those days bring back to me! My beloved mother, my sweet Septimine!" Octave regarded the old man with increasing astonishment, but, suddenly collecting himself, he grew pensive and hastened his steps, followed by the two hostages. Dazzled by the sights before him Vortigern examined with the curiosity of his age the riches of all kinds that were heaped up all around him. He could not refrain from stopping before two objects that attracted his attention above all others. The first was a piece of furniture of precious wood enriched with gilt mouldings. Pipes of copper, brass and tin, of different thicknesses rose above each other in tiers on one side of the wooden structure. "Octave," asked the young Breton, "what kind of furniture is this?"
