(Εὐρυκλείδας), an Athenian orator, who, together with Micon or Micion, possessed much influence with the people, which they used unworthily, as the Athenians under their guidance launched forth, according to Polybius, into the most unrestrained flattery towards the kings, whose favour they desired to gain, especially Ptolemy IV. (Philopator) of Egypt. Pausanias tells us that Philip V. of Macedon caused them both to be removed by poison. (Plb. 5.106 ; Paus. 2.9.)
