The first description of these island people comes in a letter sent in 523 to their tribunes by a legate from the Ostrogoth kingdom then prevailing in northern Italy. Cassiodorus was asking them to transport wine and oil across the waters to Ravenna. “For you live like seabirds,” he wrote, “with your homes dispersed, like the Cyclades, across the surface of the water. The solidity of the earth on which they rest is secured only by osier and wattle; yet you do not hesitate to oppose so frail a bulwark to the wildness of the sea.” He was not quite accurate in his description; there were already some houses constructed from the stone and brick of the mainland. He went on to say that the Veneti “have one great wealth—the fish which suffices for you all. Among you there is no difference between rich and poor; your food is the same, your houses are all alike.” Again, this was not quite true. Extant testimonials suggest that, even at an early stage in the development of the lagoon, there were rich as well as poor families. Cassiodorus then added that “your energies are spent on your salt fields; in them indeed lies your prosperity.” In this, at least, he was right. And he added the significant detail of “your boats—which like horses you keep tied up at the doors of your dwellings.” By good fortune one of these boats has emerged from the mud of the lagoon. Part of a rib of oak, and a hull of lime, have been found on the island of S. Francesco del Deserto; the boat itself dates to the fifth century. It was lying at a level that, in this period, would have been submerged except at times of low tide.
Yet Venice itself was not yet born. It is not shown in a fourth-century map of the region, in which the lagoon is depicted as a sea route without people. Venetian historians claimed, however, that the city was established at midday on 25 March 421, by a poor fisherman known as Giovanni Bono or John the Good. There are advantages to this theory, since the same date has been given to the vernal equinox, the Annunciation and the supposed date of the foundation of Rome. The triple coincidence, as well as the provident arrival of John the Good, is too good to be true; but it is part of the extraordinary Venetian ability to supplant history with myth. As the German poet, Rilke, said on a visit to the city in 1920, “as with mirrors one grasps nothing but is only drawn into the secret of its elusiveness. One is filled with images all day long, but could not substantiate a single one of them. Venice is a matter of faith.”
In fact Venice emerged over a century later, after a series of invasions by the Lombards in the late 560s and early 570s. Once more the province of Venetia was overcome by alien tribes. Unlike the Huns, however, they did not wish to plunder and depart. They intended to stay and to settle. They overran what is now called in their name the region of Lombardy. Their arrival prompted a mass exodus of the Veneti. The bishop of Aquileia moved his see to the edge of the lagoon at Grado. The bishop of Padua removed himself to Malamocco, and the bishop of Oderzo sailed to Heraclea. These men were secular as well as religious leaders; they took citizens as well as congregations, ready to create new communities on the water. Burano and Murano were extensively settled, as well as smaller islands such as Ammiana and Constanziaca; these last two disappeared beneath the waves in the thirteenth century, swallowed up by the main enemy of the island people. They have never rested in their battle against the sea.
Venice was born in this flight from the Lombards. The most recent archaeological investigations have dated the first signs of human habitation to the second half of the sixth century and to the seventh century; these remains were situated in the neighbourhood of Castello, in the east of the city, and beneath Saint Mark’s Square. There is evidence, too, that in these early years work had already begun on raising the surface of the land and reclaiming earth from water. The settlers fenced the soil with planks and poles; they drained the water; they laid down building rubble, or sediment, or sand from the dunes; they erected wooden palisades to resist the sea. It is the beginning of the city.
