amphictyony (plural amphictyonies)
- A religious foundation or co-operative shared between Greek city states during the classical period, typically to support the temple or cult of a deity shared by the city states. Also used academically to refer to similar arrangements in non-Greek cultures.
"In all probability, these covenant renewal festivals were more important than sacrifices in the cultic life of the amphictyony." Ringgren, Helmer (1966) "Israelite Religion". Fortress Press, Minneapolis. (Translated from German by David Green).
