EKEKHEIRIA (or Ececheiria) was the spirit (daimona) of truce, armistice, and the cessation of all hostilities. She was honoured at Olympia during the Olympic Games when a general truce amongst the states of Greece was declared.
Ekekheiria was closely related to the goddess Eirene (Peace).
ECECHEI′RIA (Ekecheiria), that is, the armistice or truce, which was personified and represented as a divine being at the entrance of the tempie of Zeus at Olympia; there was a statue of Iphitus, which Ececheiria was in the act of crowning. (Paus. v. 10. § 3, 26. § 2.)
