Abrizeykan

Abrizeykan in Persian mythology, is a festival of the Chaldaeans, Armenians, and Persians. It is the anniversary of a treaty of peace between Manutsheher and Afrasiab. An arrow sent by the archer Aresh, under divine guidances defined the limits of each kingdom. The river Oxus or Amu, near which it fell, became the dividing line.
