The seaway was open for increased traffic with Egypt and, more particularly, with Byzantium. Venice had already become that ancient city’s single most important trading partner, sending slaves and timber in exchange for wine, oil and wheat. In 991 Greek and Arab envoys travelled from the East to pay respect to the new doge, and a year later a treaty confirmed that Venice had been granted “most favoured” status by the Byzantine emperor. It confirmed what was already known. Venice had become the dominant trader of Europe, its commercial supremacy sustained by a vigorous and expanding navy. In return Venice offered its ships as transport for Byzantine soldiers crossing the Adriatic. The city was also, for all practical purposes, inviolable. At the time of the Magyar invasions of Lombardy, at the end of the ninth century, a stone wall was built to defend the islands of the Rialto. A great chain was placed across the water to prevent enemy ships from entering the Grand Canal. But the precautions were unnecessary. The Magyars could not reach the sea-girt city. They were beaten off in the shallow waters of the lagoon, where their ships foundered and sank. The great wall itself was demolished in the fourteenth century. It was not required.
By the eleventh century, therefore, Venice had become an autonomous and influential state. In the latter part of that century it fought with the troops of Byzantium against the Norman invaders of Sicily. The reason for the Norman adventure, as well as all the other policies and actions of Venice in this period, was very simple. No other state or city could be allowed to block the mouth of the Adriatic, thus imprisoning Venice within its own waters. This was the great fear and the abiding preoccupation.
It has become customary to describe the eleventh century as the period in which Latin Christendom emerged triumphant. This is nowhere more powerfully evinced than in the history of the Crusades. They have been construed as a direct attack upon the Muslim world, or as a form of spiritual imperialism, but the participation of Venice in the First Crusade had no such motives. The Venetians were waging economic warfare by other means. They were not concerned with the cross, or with the sword, but with the purse. The point was that rival trading cities, Genoa and Pisa in particular, were already taking part. Venice could not permit its competitors to gain an advantage in the lucrative markets of Syria and Egypt. To have a permanent presence in Antioch, or in Jerusalem, would be a source of innumerable commercial benefits. So, in the summer of 1100, a fleet of two hundred Venetian ships arrived at Joppa (Jaffa); the Venetian commanders agreed to help the crusaders on condition that the merchants of their city were given the rights of free trade in all dominions recovered from the Saracens. The terms of this practical bargain were accepted. The Venetians were then despatched to besiege the town of Caifa (Haifa) and, having achieved the surrender of that place, they returned to the lagoon before the end of the year. They were not content, however, with this single and relatively simple victory. They wished to acquire more profit from their participation in the holy cause. They established trading stations within the Syrian ports, and began a lucrative business in transporting pilgrims to the newly captured Jerusalem.
On their way to Joppa, too, they had engaged in a peculiarly Venetian piece of business. The fleet had cast anchor at the ancient Lycian town of Myra (Bari), in search of the bones of Saint Nicholas who had been bishop of that place; the saint is now better known as the progenitor of Santa Claus but, in the eleventh century, he was revered as the patron saint of sailors. The Venetians, naturally enough, wanted him. It is alleged that they arrived in the town and put to the torture four Christians, the keepers of the shrine. They learned nothing of any consequence from these unholy proceedings, however, and made do with the theft of the bones of Saint Theodore. Theodore had been the patron saint of Venice before the arrival of Mark; he was a good second-best. Yet before their departure, according to the Venetian chronicles of Andrea Morosini, a wonderful fragrance issued from a recess beneath an altar in the church itself. The scent was that of Saint Nicholas. So he was removed, too, and brought back in triumph to Venice where his bones were lodged in the monastery of Saint Nicholas on the Lido. That is the story, at least. In fact the remains of Saint Nicholas, if such they are, have remained in Bari to this day. Whether the tale reveals more of Venetian mendacity, or of Venetian greed, is an open question.
