But we can move closer to the merchant. We can glimpse more of his life. A manuscript notebook of the early fourteenth century, known as the Zibaldone da Canal, has survived. It was compiled by a merchant, of unknown name, and is filled with arithmetical and geometrical notations together with what the merchant calls “many beautiful and subtle calculations.” There are medical remedies of an eminently practical nature, together with the most egregious superstitions. He notes that cheese becomes lighter as it dries out, so that it must be weighed carefully at the end of a voyage. He estimates the profit to be earned from gold smuggled into Tunis. He calculates the length of voyages. He recommends that a traveller, on first boarding his ship, should invoke saints Oriele and Tobias. He remarks, also, that there is “a time to threaten and not to fear.” The heart of the merchant is thereby laid bare.
In Venice according to one senator, “everything is up for sale.” He was referring in particular to political office, when the state itself became the object of commercial speculation, but he was entirely correct in a wider sense. Venice became the market of the world. “Indeed it seems,” one visitor wrote in 1494, “as if the whole world flocks there, and that human beings have concentrated all their force for trading.” This notion of “force,” the energy and power released by commerce, is the perfect word for the tempest of Venetian business. To Venice came the wines of Crete and the cinnamon of the Indies, the carpets of Alexandria and the caviar of Caffa, the sugar of Cyprus and the dates of Palestine. Cloves and nutmegs arrived from the Moluccas by way of Alexandria; the camphor of Borneo was brought to the lagoon together with the pearls and sapphires of Ceylon; the shawls of Kashmir lay beside the musk of Tibet, while the ivory of Zanzibar was unloaded with the rich cloths of Bengal. The Venetian ambassadors signed commercial treaties with the soldan of Egypt and the khan of Tartary, the sultan of Aleppo and the count of Biblos. The sons of nobles became apprentices at sea. Marco Polo was a merchant.
Fernand Braudel, in Le Temps du Monde (1979), characterises Venice in 1500 as the centre of the world economy. In 1599 it was described by Lewes Lewkenor as “a common and general market to the whole world.” In Coryat’s Crudities (1611) Saint Mark’s Square itself is called the “market-place of the world.” The city dominated the Adriatic, and insisted that all of its trade passed through its own ports. Venice fought off all other claimants. It was the quintessential merchant city, the ultimate bazaar.
The early trade fairs of Europe were conducted in Venice, perhaps from the examples of Egypt and Syria. The annual fair of the Sensa, with its origins in the twelfth century, was devoted to luxury goods; there were no less than twenty-four shops, for example, reserved for the goldsmiths and the silversmiths. It took place in Saint Mark’s Square, lasted for fifteen days, and welcomed some hundred thousand visitors. There were glass-blowers and painters and armourers; in fact, craftsmen of every kind. Trade then became a carnival and an entertainment. It became the object of festive ritual, just as the harvest rites of the countryside had a spiritual as well as a secular importance.
Yet there is a sentence from Voltaire that underlines the economic significance of this trade in luxuries—“Le superflu, chose très nécessaire”; luxury was necessary because it stimulated trade. The possession of luxuries, for example, was a vital element in the attainment of status. It has been argued that the growth of luxury is largely responsible for the rise of modern capitalism, in which case Venice was a pioneer capitalist in more than one sense. In its exploitation of raw materials, in its obsession with profit, in its rational organisation of trade and manufacture, and in the size of its operations across the known world, it was the very model of capitalistic enterprise. These urban merchants and shopkeepers learned how to diversify, to create new occupations and products, to seek for simplicity in all forms of exchange.
