(Σθενελα̈ίδας), a Spartan, who held the office of ephor in B. C. 432, and, in the congress of the Lacedaemonians and their allies at Sparta in that year, vehemently and successfully urged the assembly to decree war with Athens. The speech which Thucydides puts into his mouth on this occasion is strongly marked by the characteristics of Spartan eloquence,--brevity and simplicity. (Thuc. 1.85, 86, 8.5; Paus.3.7.)
