LADOCEIA(τὰ Λαδόκεια), a place in Arcadia, in the district Maenalia, and, after the building of Megalopolis, a suburb of that city, was situated upon the road from the latter to Pallantium and Tegea. Here a battle was fought between the Mantineians and Tegeatae, B.C. 423, and between the Achaeans and Cleomenes, B.C. 226. Thucydides calls it Laodicium (Λαοδίκιον) in Oresthis. (Paus. 8.44.1; Thuc. 4.134; Plb. 2.51, 55.) [ORESTHASIUM]
