MithraMithra ( Miθra, 𐎷𐎰𐎼 Miça), commonly known as Mehr or Mithras among Romans, is an ancient Iranian deity of covenants, light, oath, justice, the sun, contracts, and friendship. In addition to being the divinity of contracts, Mithra is also a judicial figure, an all-seeing protector of Truth, and the guardian of cattle, the harvest, and the Waters. The Romans attributed their Mithraic mysteries to Zoroastrian Persian sources relating to Mithra.
VishtaspaVishtaspa (𐬬𐬌𐬱𐬙𐬁𐬯𐬞𐬀 ; 𐎻𐏁𐎫𐎠𐎿𐎱 ; گشتاسپ ; Ὑστάσπης ) is the Avestan-language name of a figure of Zoroastrian scripture and tradition, portrayed as an early follower of Zoroaster, and his patron, and instrumental in the diffusion of the prophet's message. Although Vishtaspa is not epigraphically attested, he is – like Zoroaster – traditionally assumed to have been a historical figure, although obscured by accretions from legend and myth. In Zoroastrian tradition, which builds on allusions found in the Avesta, Vishtaspa is a righteous king who helped propagate and defend the faith.
AvestaThe Avesta (ə'vɛstə) is the primary collection of religious texts of Zoroastrianism, composed in the Avestan language. The Avesta texts fall into several different categories, arranged either by dialect, or by usage. The principal text in the liturgical group is the Yasna, which takes its name from the Yasna ceremony, Zoroastrianism's primary act of worship, and at which the Yasna text is recited. The most important portion of the Yasna texts are the five Gathas, consisting of seventeen hymns attributed to Zoroaster himself.
