When Lisuarte had quitted Trebizond on the adventure in which he was an unwilling partaker, the Emperor of that country, father of his inamorata, was informed of the true character of the prodigious damsel who had carried him off by a letter which was closed with sixty-seven seals and which announced that Constantinople was about to be besieged by Armato, the Turkish Soldan, who had placed himself at the head of a league of sixty-seven princes for the purpose of waging war against the imperial city. Meanwhile Lisuarte was given into the care of the King of the Giants' Isle, whose daughter Gradaffile fell in love with him, procured his escape, and followed him to Constantinople, whence he at once betook himself for the purpose of combating the infidels who invested it. In this task he was assisted by Perion, who now arrived in Greece, after having accomplished the behest of the Lady of the Apes. In course of time Lisuarte became conscious that duty now called him to effect the release of his sleeping ancestors from the spell in which they had been cast for the purpose of prolonging their existences. After many adventures, which we spare the reader, he obtained possession of the fatal sword and proceeded to the Firm Island, where he broke the enchanted sleep into which Amadis, Esplandian, and the rest had been lulled by the far-sighted Urganda.

Perion had also gone thither from a similar reason, but on the request of the Duchess of Austria had accompanied that lady to her dominions, which were in the grip of a usurper. On his return from this chivalrous task he encountered his kinsman Lisuarte, and both champions were in the act of preparing their wedding festivities when Perion and the Emperor of Trebizond were carried off by pagan treachery in the midst of a hunting expedition. Lisuarte, following on their track, was also seized by the enemy, and imprisoned along with those he had sought to succour. Amadis of Greece
