Zeno was born at Cittius, a small maritime town in the Island of Cyprus. This place having been originally peopled by a colony of Phoenicians, Zeno is sometimes called a Phoenician; but at the period when he flourished, it was chiefly inhabited by Greeks. The date of his birth is uncertain, but must have been about the year B.C. 362. His father was a merchant, and Zeno appears to have been, in the early part of his life, engaged in mercantile pursuits. He received a very liberal education from his father, whom, we are told, perceived in his son a strong inclination for philosophical studies, and who purchased for Zeno the writings of the Socratic philosophers; which were studied with avidity, and which undoubtedly exercised a considerable influence over his future thinkings. When about thirty years of age, he made a trading voyage from Cittius to Athens, with a very valuable cargo of Phoenician purple, but was unfortunately shipwrecked on the coast of Greece, and the whole of his freight destroyed. It is supposed that this severe loss, which must have considerably reduced his means, materially influenced Zeno, and induced him to embrace the tenets of the Cynics, whose leading principle was a contempt of riches. We are told that upon is first arrival in Athens, he went into the shop of a bookseller, and took up, by accident, a volume of the "Commentaries of Xenophon." Alter reading a few pages, Zeno was so much delighted with the work, that he asked the bookseller to direct him where he might meet such men as the author? Crates, the Cynic philosopher, passed by at the time, and the bookseller said, "Follow that man!" He did so, and after listening to several of his discourses, was so pleased with the doctrines of the Cynics, that he became a disciple. He did not long remain attached to the Cynic school--their peculiar manners were too gross for him; and his energetic and inquiring mind was too much cramped by that indifference to all scientific investigation which was one of their leading characteristics. He therefore sought instruction elsewhere, and Stilpo, of Megara, became his teacher, from whom he acquired the art of disputation, in which he afterwards became so proficient. The Cynics were displeased at his following other philosophy, and we are told that Crates attempted to drag him by force out of the school of Stilpo, on which Zeno said, "You may seize my body, but Stilpo has laid hold of my mind." The Megaric doctrine was, however, insufficient. Zeno was willing to learn all that Stilpo could teach, but having learned all, his restless and insatiable appetite for knowledge required more, and after an attendance of several years upon the lectures of Stilpo, he passed over to the expositors of Plato, Xenocrates, and Polemo. The latter philosopher appears to have penetrated Zeno's design in attending the various schools--_i.e._, to collect materials from various quarters for a new system of his own;
