Armenian mythology originated in ancient Indo-European traditions, specifically Proto-Armenian, and gradually incorporated Hurro-Urartian, Mesopotamian, Iranian, and Greek beliefs and deities.

[4] After the establishment of Iranian dominance in Armenia in the 1st millennium BCE, Zoroastrianism had a major influence on Armenian religion.

[5] For example, the supreme god of the Armenian pantheon, Vanatur, was later replaced by Aramazd (the Parthian form of Ahura Mazda).

In the Hellenistic age (3rd to 1st centuries BCE), ancient Armenian deities were identified with ancient Greek deities: Aramazd with Zeus, Anahit with Artemis, Vahagn with Heracles, Astłik with Aphrodite, Nane with Athena, Mihr with Hephaestus, Tir with Apollo.

Basic information about Armenian pagan traditions were preserved in the works of ancient Greek authors such as Plato, Herodotus, Xenophon and Strabo, Byzantine scholar Procopius of Caesarea, as well as medieval Armenian writers such as Movses Khorenatsi, Agathangelos, Eznik of Kolb, Sebeos, and Anania Shirakatsi, as well as in oral folk traditions.

Originally native Armenian in nature, the pantheon was modified through, Hurro-Urartian, Semitic, Iranian and Greek influences.
