Therefore Kherboga, the mayor of the palace or rather the leader of the troops of the king of the Persians, whom they were accustomed to call Sogdianus,[168] the name of previous king of the Persians (as the Romans are accustomed to call their leaders Caesars), while he was still within the kingdom of Persia, in the province called Khorasan (some say that this land derives its name by corruption from the name of the land around the Caucasus), was summoned by frequent messengers from Cassianus, the ruler of the city of Antioch, to bring help to him in his beleaguered position. Cassianus promised that, if he drove off the Franks, he would either turn over to him the liberated city, or provide him with a gift equal to his great labor. When the general, enticed by this promise, had put together a huge army, and had asked for and received permission to kill the Christians from the chief pontiff of their heresy (for even they have their Pope, in the likeness of ours), he quickly set off to relieve the siege of Antioch. The prefect of Jerusalem (whom they call in their barbaric language "emir") also immediately increased the invading forces with his own army, which was, in turn, augmented by the considerable forces of the king of Damascus. The pagans recruited by the infidel prince, in addition to the Turks, Saracens, Arabs, and Persians (who are already familiar to historians), bore new names: they were the Publicans, the Kurds, the Azimites, and the Agulani, together with innumerable others, who were by no means human, but monsters. Three thousand of those who were called Agulani were said to be present, and they were afraid neither of swords, lances, arrows, nor any kind of arms, because they and their horses were covered with armor everywhere. In battles the only weapons they used were their swords. Kherboga therefore, with the great arrogance of the pagans, strove to drive the Franks from Antioch. As the prince approached the city, the son of the dead Cassian, Sensadolus by name, met him, and, with great sadness, said to him, "Since your strength is widely renowned, and the victories of you and your people are everywhere judged to be incomparable, certainly my hope for your aid will not be disappointed, O most victorious of men. No one denies the worth of your judgements; because of the brilliance of your deeds, your power is worshipped everywhere; therefore I need not be ashamed of lamenting my misfortune in your presence. I know for certain that I am not begging in vain for the things for which I ask. Your excellency remembers that you received ambassadors from my father when Antioch was being besieged, and that, while you were deciding to come to his aid, you heard that the city had been captured by the Franks. Now my father is dead, and I am besieged in the citadel of the city, undoubtedly awaiting the same fate that overtook my father. If they have invaded Antioch, and have done the same to many cities
