1. Of CITIUM, a city in the island of Cyprus, founded by Phoenician settlers. He was the son of Mnaseas. Some authorities assign other names to his father, but with less probability (D. L. 7.1, ib. Menag.). He is said to have been early won over to the pursuit of philosophy through books of the Socratics, which his father was accustomed to bring back from Athens when he went thither on trading voyages; and to have devoted himself to it entirely when (through the direction of an oracle, as is said) at the age of 22, or, according to others, 30 years, having been shipwrecked in the neighbourhood of Peiraeeus, he was led to settle in Athens (ibid. 2, 4, 5, 28). Whether he lost all his property in the shipwreck (Seneca, de Tranqu. Animi, 100.14; Plut. de cap. ex host. Utilitate, p. 87a), or, what is considerably less likely, remained in possession of a fabulous fortune of 1000 talents (D. L. 7.13, comp.15, 22, 5), his moderation and contentment had become proverbial (Ζήνωνος ἐγκρατέστερος, D. L. 27, &c., comp. 26, 13, 16; Suid. s. v.), and an admiring recognition of his virtues shines through even the ridicule of the comic poets (Philemon, Posidippus, &c.; D. L. 7.27, &c.; Clem. Al. Strom. ii. p. 413). Though weakness of body is said to have first determined him to live rigorously and simply (D. L. 7.1; Antig. Caryst. apud Athen. 12.2), and harden himself (D. L. 26, &c.), yet an inclination for being independent of want seems already at an early period to have come in as an additional motive, and to have led him to the cynic Crates, to whom, however, he could only attach himself with a twofold reservation; for he could not adopt either the contempt for established usages which characterised their mode of life, nor their scorn of free and comprehensive knowledge (Ibid. 3, 17, 22). Yet he seems to have been still entirely under their influence when he wrote his Πολιτεία (Ibid. 4 ; comp. Plut. de Alex. fortit. 1.6). When it was that, against the dissuasion of Crates, he betook himself to the Megaric Stilpo (D. L. 7.24. 2), we do not learn; and equally scanty are the accounts which we have respecting his intercourse with the two other contemporary Megarics, Diodorus Cronus and Philon (ibid. 16, 25, 15, 16) on the one hand, and with the Academics, Xenocrates and Polemon (ibid. 2, 35, comp. Solid. s. v.) on the other. Only from the logic of the Stoics we see that in this branch of science they approached considerably nearer to the Megarics than to the Academics. The period which Zenon thus devoted to study is extended by one unauthenticated statement to twenty years. (D. L. 7.4, comp. 2.) At its close, and after he had developed his peculiar philosophical system, to which he must already have gained over some disciples, he opened his school in the porch adorned with the paintings of Polygnotus (Stoa Poicile), which, at an earlier time, had been a place in which poets met (Eratosthenes in D. L. 7.5). From it his disciples were called Stoics, a name which had before been applied to the above-mentioned poets, and by which also the grammarians who assembled there probably at a later time were known. Previously his disciples were called Zenonians. Among the warm admirers of Zenon was king Antigonus Gonatas of Macedonia : for although the correspondence between the two, professing to have
We are not able to ascertain with certainty either the year of Zenon's birth, or that of his death, and cannot regard as accurate the statements that he came to Athens at the age of 22 or even 30 years, that he pursued his philosophical studies for 20 years, and presided over his school for 58 years (D. L. 28), even though we should prefer the statement that he reached the age of 98 (ibid.), to that of his disciple Persaeus, according to which he was only 72 years old when he died. He is said to have been still alive in the 130th Olympiad (ibid. 6), and this is certainly in accordance with the statements which make him a disciple of Polemon, who became president of the Academic school in Ol. 116. 2, and also with what we are told about his intercourse with Antigonus Gonatas, who came to the throne in Ol. 124, and with Arcesilas (Cic. Ac. 1.9, 13, 2.24).
