At that time not a single man of weight and importance recognized that the primary source of all these phenomena lay in the Kabbala and the Zohar. Jacob Sasportas, originally from Africa, had lived in Amsterdam and London and, at this time, was in Hamburg. He was born about 1620, and died 1698. A man of courage and keen penetration, whose word had weight through his Talmudical learning, Sasportas from the first combated this Messianic rage with passionate warmth. He was unwearied in sending letter after letter to the various communities and their guides in Europe, Asia, and Africa, to unmask the gross deceptions practiced, and to warn against the sad consequences. But even he was entangled in the snares of the Kabbala, and adopted its principles. On the ground of this spurious philosophy, thoroughgoing enthusiasts were more in the right than half-hearted adherents. Spinoza, who might have scattered this thick mist with his luminous ideas, was not only estranged from Judaism and his race, but even hostile to them, and regarded the prevailing perplexities with indifference or malice. The accounts of Sabbataï Zevi and the Messianic excitement either came direct, or in a roundabout way by Alexandria, to Venice, Leghorn, and other Italian cities. Venice was led by the bigoted Kabbalist Moses Zacut, Spinoza's very uncongenial fellow-student, who had formed the design of migrating from Amsterdam through Poland to Palestine, but stopped short in Venice. Far from opposing the delusion of the multitude, he encouraged it, as did the rabbinate of Venice. The news from Smyrna had most striking effect upon the great and the lesser Jerusalem of the North. The prophet of Gaza, who was not devoid of sober calculation, had directed his propagandist circulars to the most considerable and the richest communities--Amsterdam and Hamburg. These entered into close relationship with the new Messianic movement. The Jews of Amsterdam and Hamburg received confirmation of the extraordinary events at Smyrna from trustworthy Christians, many of whom were sincerely rejoiced thereat. Even Heinrich Oldenburg, a distinguished German savant in London, wrote to his friend Spinoza (December, 1665):-- "All the world here is talking of a rumor of the return of the Israelites, dispersed for more than two thousand years, to their own country. Few believe it, but many wish it.... Should the news be confirmed, it may bring about a revolution in all things."
