was a Spartan
general of the 5th century BC
; he was the son of Cleandridas
, who had been expelled from Sparta for accepting Athenian
bribes in 446 BC
and had settled at Thurii
. His mother may have been a helot
. When Alcibiades
urged the Spartans to send a general to lead the Syracusan
resistance against the Athenian expedition
, Gylippus was appointed (414 BC
), and his arrival was a turning point of the struggle. More daring than Nicias, the Athenian commander he faced, he was able to gain an upper hand by driving the Athenians from key strategic locations and essentially break the siege. When Athens sent Demosthenes with reinforcements, he too was defeated by Gylippus, which ultimately lead to the downfall of the Athenian campaign in Syracuse.
Diodorus, probably following Timaeus, represents him as inducing the Syracusans to pass sentence of death on the captive Athenian generals, but there is also the statement of Philistus (Plutarch, Nicias, 28), a Syracusan who himself took part in the defence, and Thucydides (vii. 86), that he tried, though without success, to save their lives, wishing to take them to Sparta as a signal proof of his success.
Gylippus, like his father, met his downfall in a financial scandal; entrusted by Lysander with an immense sum which he was to deliver to the ephors at Sparta, he could not resist the temptation to enrich himself and, on discovery, went into exile, having been condemned to death in his absence.
