(Κυκλιάδας) was strategies of the Achaeans in B. C. 208, and, having joined Philip V. of Macedon at Dyme with the Achaean forces, aided him in that invasion of Elis which was checked by P. Sulpicius Galba. In B. C. 200, Cycliadas being made strategus instead of Philopoemen, whose military talents he by no means equalled, Nabis took advantage of the change to make war on the Achaeans. Philip offered to help them, and to carry the war into the enemy's country, if they would give him a sufficient number of their soldiers to garrison Chalcis, Oreus, and Corinth in the mean time; but they saw through his plan, which was to obtain hostages from them and so to force them into a war with the Romans. Cycliadas therefore answered, that their laws precluded them from discussing any proposal except that for which the assembly was summoned, and this conduct relieved him from the imputation, under which he had previously laboured, of being a mere creature of the king's. In B. C. 198 we find him an exile at the court of Philip, whom he attended in that year at his conference with Flamininus at Nicaea in Locris. After the battle of Cynoscephalae, B. C. 197, Cycliadas was sent with two others as ambassador from Philip to Flamininus, who granted the king a truce of 15 days with a view to the arrangement of a permanent peace.
