The earliest settlements were twelve: Grado, Bibbione, Caorle, Jesolo (now Cavallino), Eraclea, Torcello, Burano, Rivoalto (now Venice), Malamocco, Poveglia, Cluges Minor (actual site now unknown, but not Sotto Marina, as sometimes stated), Cluges Major (now Chioggia). Of these, Grado was occupied by the Aquileians; Rivoalto and Malamocco by the Paduans; Eraclea by the Bellonsese; Torcello and Burano by the Altinese. To the pious imagination of chroniclers these migrations were not without divine admonition. In 568 the terrible Lombards were threatening Altinum, whose inhabitants entreated the help of heaven with tears and prayers and fastings; and, lo! they saw the doves and many other birds bearing their young in their beaks flying from their nests in the walls of the city. This was interpreted as a sign from God that they also were to expatriate themselves and seek safety in flight. They divided into three bodies, one of which turned to Istria, another to Ravenna. The third remained behind, uncertain whither to direct their steps. Three days they fasted, and at length a voice was heard saying: “_Salite alla torre e guardate agli astri._” (Ascend the tower and look at the stars.) [Illustration: S. FOSCA AND THE DUOMO, TORCELLO] [Illustration: PONTE S. GIUSTINA] Their good Bishop Paul climbed the tower, and to his gaze the very stars of the firmament seemed to set themselves in a constellation that figured forth the fateful group of islands in the lagoon before him. His flock, following this warning from heaven, went forth, headed by their bishop and clergy bearing the sacred vessels and relics, and passed to an island high and fertile, which they called Torcello, from one of the twelve towers of their old city. The very hierarchy of heaven, from Our Lord and His Blessed Mother to St Peter and the Baptist, even to Giustina, the martyred little maid of Padua, appeared to Mauro, the priest, in a vision, as he paced the sea shore, and in sweet voices bade him build here a church and there a church in their honour. The immigrants therefore had come to make the lagoons their permanent home. Their new city was organised. In process of time churches were built; trade guilds were formed; painters and mosaicists enriched the buildings. The marble seat on the grass-grown piazza of Torcello, to this day called Attila’s chair, was probably the official seat of the tribune when he administered justice to the people.
