Zeno in Harpers Dictionary of Classical Antiquities (1898)

The Eleatic philosopher, a native of Elea (Velia) in Italy, son of Teleutagoras, and the favourite disciple of Parmenides. He was born about B.C. 488, and at the age of forty accompanied Parmenides to Athens. (See Parmenides.) He appears to have resided some time at Athens, and is said to have unfolded his doctrines to men like Pericles and Callias for the price of 100 minae. Zeno is said to have taken part in the legislation of Parmenides, to the maintenance of which the citizens of Elea had pledged themselves every year by an oath. His love of freedom is shown by the courage with which he exposed his life in order to deliver his native country from a tyrant. Whether he perished in the attempt or survived the fall of the tyrant is a point on which the authorities vary. They also state the name of the tyranny differently. Zeno devoted all his energies to explain and develop the philosophical system of Parmenides. See Zeller's Pre-Socratic Schools (1881).
