Leaving Mount Gargano, we travelled a hundred and fifty miles, to a city in the power of the Saracens, named Bari[44], which was formerly subject to Beneventum. It is seated on the sea, and is fortified to the south by two very wide walls; but to the north it stands exposed to the sea. Here we obtained from the prince of the city, called the sultan, the necessary arrangements for our voyage, with two letters of safe conduct, describing our persons and the object of our journey, to the prince of Alexandria, and to the prince of Babylonia[45]. These princes are under the jurisdiction of the Emir-al-Mumenin, who rules over all the Saracens, and resides in Bagada and Axinarri, which are beyond Jerusalem. From Bari we proceeded to the port of the city of Tarentum, a distance of ninety miles, where we found six ships, having on board nine thousand captives of the Christians of Beneventum. In the two ships which sailed first, and which were bound for Africa, were three thousand captives; and in the two which followed them, and which went to Tunis, there were also three thousand. The two others, which likewise contained the same number of Christian captives, carried us to the port of Alexandria, after a voyage of thirty days. Here we were prohibited from landing by the captain of the sailors, who had sixty under his command, until we had given six _aurei_ for our leave. Thence we went to the prince of Alexandria, and showed him the letter which the sultan had given us, to which, however, he paid no attention, but obliged each of us to pay thirteen deniers, and then gave us letters to the prince of Babylonia. It is the custom of these people to take in weight only what can be weighed; and six of our sols and six deniers make three sols and three deniers of their money.
