(3) Other pupils. Other pupils of Zeno were Persæus, a countryman and companion of Zeno;25 Aratus, the well-known poet of Soli;26 Dionysius of Heraclea in Pontus, who afterwards joined the Cyrenaic or Epicurean School;27 and Sphærus from the Bosporus, who studied first in the School of Zeno, and afterwards in that of Cleanthes, and was the friend and adviser of Cleomenes, the unfortunate Spartan reformer.28 Of a few other pupils of Zeno the names are also known;29 but nothing beyond their names. No appreciable addition was made to the Stoic doctrine by any one of them.
