Vedic Culture in Ancient Turkey

I am always interested in researching Vedic culture in Iran (during Sumerian and Babylonian time periods), this reference takes Vedic culture as far West as Anatolia (modern day Turkey). I came across Manasataramgini stating

“In 1380 BCE, the Hittites made a comeback and waged war against the Hurrian state of the Mitanni led by an Indo-Aryan elite (e.g., their king *Sātavāja>Sattivaza), who were likely in an alliance with the Egyptians and had arisen to considerable power between 1600-1500 BCE. The treaty between Suppiluliuma I and Sattivaza is famous for listing the Indo-Aryan gods, Mitra, Varuṇa, Indra and the Nāsatya-s [Ashvins].”

I looked up the source material and share below the actual clay tablet written in Hittite, which is Indo-Anatolian ('sister' to Indo-European) in cuneiform script.

The translation of the whole Peace Treaty is available at HeritageInstitute.com. The pertinent verse is given below which invokes the Hittite Storm-god (Taru) associated with a three pronged thunderbolt and bull, along with Mitra, Varuna, Indra, and the Ashwins as well as the Babylonian gods Anu, Antu, Enlil, and a host of other deities related to the "Heavens and Earth."   

"... the Storm-god, Lord of Heaven and Earth, the Moon-god and the Sun-god, the Moon-god of Harran, heaven and earth, the Storm-god, Lord of the kurinnu of Kahat, the Deity of Herds of Kurta, the Storm-god, Lord of Uhušuman, Ea-šarri, Lord of Wisdom, Anu, Antu, Enlil, Ninlil, the Mitra-gods, the Varuna-gods, Indra, the Nasatya-gods, Lord of Waššukanni, the Storm-god, Lord of the Temple Platform (?) of Irrite, Partahi of Šuta, Nabarbi, Šuruhi, Ištar, Evening Star, Šala, Belet-ekalli, Damkina, Išhara, the mountains and rivers, the deities of heaven and the deities of earth."

This shows the dispersion of Vedic practitioners in the ancient world that both influenced and were influenced by other cultures.
