At this time there reigned in Trebizond a Christian king named Caloianni,[615] who had a daughter named Despinacaton,[616] who was very beautiful, being considered the most beautiful woman of that time, and throughout Persia was spread the fame of her loveliness and grace. As this king was already much molested and troubled in his peaceful dominions by the Ottoman Grand Turk, and finding himself in a bad way and in danger of losing his kingdom, considering the great power of his enemy, he resolved to send an ambassador to Tauris, where Sultan Assambei[617] lived, to ask his assistance, knowing him to be a magnanimous monarch. The ambassador, who was most desirous to obtain the request of his sovereign and to return with full satisfaction, entreated Assambei not to refuse to give aid to his master, showing him many reasons why the destruction of the Christian king would cause harm to his dominions. Assambei being young and unmarried, and already in love with the above-mentioned lady from having heard so much talk of her beauty and talents, replied to the ambassador that if his master would give him his daughter as his wife, he would aid him against the Ottoman not only with his army, but also with his purse, and in person. The ambassador departed with this answer, and when he came to his sovereign expressed to him what Assambei demanded. Seeing that he had not sufficient power to resist the enemy who just then was attacking him, he was induced to agree to the request of Assambei, giving him his daughter as his wife, on the condition that she might observe the Christian faith and keep a chaplain to perform the sacred offices as ordered by our true religion. Having made this compact Despinacaton arrived in Tauris accompanied by many lords: some sent by Assambei and many others coming from Trebizond. There also came with her many young maidens, daughters of noblemen of high condition, who were always to remain with her. She had also a greatly venerated chaplain, a worthy person, who always celebrated the eucharist according to the Christian custom while she lived with Ussuncassano, which she did a long time, and always in observance of our faith. She had her chapel in a separate place, saying her prayers there whenever it pleased her. This lady had four children: the eldest was Assambei;[618] the others were daughters, two of whom are still alive, and Christians. CHAP. X. The Ottoman makes preparations against Assambei and Caloianni, who send ambassadors to the Venetians, requesting their alliance, and asking for artillery; in the meantime, the Ottoman sends a Bassà, with his troops, to invade Persia. Assambei having marched against him, defeats him in a battle. The Grand Turk, collecting another army, sends against him and defeats him. He then retreats to Tauris. Afterwards, marching against the Soldan who had taken from him the city of Orfà, he defeats him near that place.
