Not very far off stood, until quite the end of the last century, a curious old house, with a figure of St Christopher painted upon it, which doubtless had a lamp constantly burning before it. Possibly it was in honour of the saint here represented that the future Discoverer of the New World was christened Christopher. On entering the city proper, through the arch of St Andrea, the prospect, in the days of Columbus' youth, was by no means cheerful. The houses, like those of Edinburgh, rose seven and even eleven storeys, making the narrow courts and passage-like streets look not unlike dark openings in a Californian cañon. The hilly position of the town, however, lent itself admirably to picturesque effects, and the brilliance of the deep blue sky above, and of the broad streaks of sunlight falling on the squares and little piazza, brightened what might otherwise have been exceedingly gloomy and depressing. The palaces of the nobility looked more like fortresses than civic residences, with scarcely a window on the street. Each possessed a tall, turreted watch-tower of red brick, picked out with marble, the finest specimen of which, now existing, is that of the Imbriaci. The churches and oratories were amazingly numerous, but they were nearly all exactly alike, built in very plain Gothic architecture, with façades streaked with alternated layers of black and white marble. A few have escaped the vandalistic restorations of the 17th and 18th centuries, and of these the best remaining specimens are the Cathedral, San Matteo Doria, Santa Maria del 'Orto (desecrated), San Cosmo, San Donate, San Stefano, and Sant Agostino (desecrated). But in the 15th century they were to be met with at every turn of the street, giving a very peculiar appearance to the city. The finest palaces bordered the Ripa by the port, and these were so beautifully decorated with frescoes and gilding that Petrarch declared that "nothing could be imagined more magnificent." The Strade Nuova, Nuovissima, and Balbi, with their splendid Renaissance palaces, did not come into existence until late in the 16th and 17th centuries. The Cathedral was in much the same condition as at present, and the Bank of St George, now in process of restoration, was considered one of the wonders of the world.
