Out of the quarrel one man issued with a noble historic reputation. Fra Paolo Sarpi (1552-1623) was the last of the great Venetians. In boyhood he was so precocious a scholar that at eighteen he was made professor of Positive Theology, and, a little later, of Philosophy and of Mathematics. Grown up, he became a man of science, the foremost of his time excepting Francis Bacon. He discovered the valves of the veins, and also, independently of Harvey, the circulation of the blood. He made discoveries in optics. He studied heat, light, sound, colour, pneumatics, the magnetic needle. In astronomy Galileo called him, "_il mio padre e maestro_--my father and my master." Sir Henry Wotton, the English ambassador to Venice, said, Fra Paolo is "as expert in the history of plants as if he had never perused any book but Nature." In addition to these achievements, he wrote a very celebrated history of the Council of Trent. At the time of the breach with the Papacy, this brilliant savant was appointed Theological Counsellor to the Republic, and was abruptly flung into the confusion and passion of violent political strife. Deeply patriotic,--his last thought was for Venice, "_Esto perpetua_, may she live forever,"--he held a brief, as it were, for his country, and as her advocate argued her cause before all Europe with brilliant success. At this period the Venetian Signory belonged, in spirit at least, to an international political party which was opposed to Spain and to the Papacy, and for that reason was favoured by the French, especially when Henry of Navarre was on the throne. In fact, this quarrel between Venice and the Papacy may be considered an episode in the great struggle between the party of European freedom and the tyrannical House of Hapsburg, seated on the thrones of Spain and Austria, and supported by the Papacy. But Venice was not able to concentrate her attention upon European affairs. Later in the century war with the Turks was renewed; she was too weak to resist them single-handed, and, after a struggle which lasted for twenty-five years, she lost Crete (1669). Not many years later, having obtained allies, she renewed the war, fought with great gallantry, and actually conquered the Morea, which, on the conclusion of hostilities, was ceded to her (1699). This conquest, now best remembered from the fact that in the attack on Athens a Venetian bomb blew up the Parthenon, was the last great military exploit of the Venetians, and within twenty years the Morea was lost again.
