The first flight to the lagoons for shelter was caused by the invasion of Attila in the fifth century, so that in endeavouring to throw back the thought of the reader to the former solitude of the islands, I spoke of them as they must have appeared “1300 years ago.” Altinum, however, was not finally destroyed till the Lombard invasion in 641, when the episcopal seat was removed to Torcello, and the inhabitants of the mainland city, giving up all hope of returning to their former homes, built their Duomo there. It is a disputed point among Venetian antiquarians, whether the present church be that which was built in the seventh century, partially restored in 1008, or whether the words of Sagornino, “ecclesiam jam vetustate consumptam recreare,” justify them in assuming an entire rebuilding of the fabric.
