And it was now, indeed, that Genoa reached, perhaps, the zenith of her power. For in 1284 comes the great victory of Meloria, which laid Pisa low. Enraged partly at the success of Genoa in the East, partly at her growing power and general wealth, Pisa, with that extraordinary flaming and ruthless energy so characteristic of her, determined to dispose of Genoa once and for all. Nor were the Genoese unwilling to meet her. Indeed, they urged her to it. The two fleets, bearing some sixty thousand men, that of Pisa commanded by a Venetian, Andrea Morosini, that of Genoa by Oberto Doria, met at Meloria, not far from Bocca d'Arno, when the Pisans were utterly defeated, partly owing to the treachery of the immortal Count Ugolino, who sailed away without striking a blow.[1] Yet in spite of her defeat Pisa carried on the war for four years, when she sued for peace, which, however, she could not keep, so that in 1290 we find Corrado Doria sailing into the Porto Pisano, breaking the chain which guarded it, and carrying it back to Genoa, where part of it hung as a trophy till our own time on the facade of the Palazzo di S. Giorgio. Nor were the Genoese content, for soon after this victory we find them, led by Lamba Doria, utterly beating the Venetians at Curzola, in the Adriatic, where they took a famous prisoner, Messer Marco Polo, just returned from Asia. They brought him back to Genoa, where he remained in prison for nearly two years, and wrote his masterpiece. Whether it was the influence of so illustrious a captive, or merely the natural expression of their own splendid and adventurous spirit, about this time the Doria fitted out two galleys to explore the western seas, and to try to reach India by way of the sunset. Tedisio Doria and the brothers Vivaldi with some Franciscans set out on this adventure, and never returned.
