Founder of the Arsacid Dynasty of Armenia

Tiridates I was King of Armenia beginning in 53 AD and the founder of the Arsacid dynasty of Armenia. The dates of his birth and death are unknown. His early reign was marked by a brief interruption towards the end of the year 54 and a much longer one from 58 to 63. In an agreement to resolve the Roman–Parthian conflict in and over Armenia, Tiridates I, who was one of the brothers of Vologases I of Parthia, was crowned king of Armenia by the Roman emperor Nero in 66; in the future, the king of Armenia was to be a Parthian prince, but his appointment required approval from the Romans. Even though this made Armenia a client kingdom, various contemporary Roman sources thought that Nero had de facto ceded Armenia to the Parthian Empire.

In addition to being king, Tiridates I was also a Zoroastrian priest and was accompanied by other magi on his journey to Rome in 66. In the early 20th century, Franz Cumont speculated that Tiridates was instrumental in the development of Mithraism which ultimately became the main religion of the Roman Army and spread across the whole empire. Furthermore, during his reign, he started reforming the administrative structure of Armenia, a reform which was continued by his successors, and which brought many Iranian customs and offices into it.

Background

Tiridates was the youngest son of Vonones II, who was king of Media Atropatene, and then later the Parthian Empire. Tiridates had two elder brothers named Pacorus (the eldest) and Vologases. Tiridates' name means "given by Tir". Tir is the Zoroastrian angel (Yazad) of literature, science and art based on the Avestan Tishtrya and was equated with the Greek Apollo by way of the process of interpretatio graeca.

Accession

In 51 the Roman procurator of Cappadocia, Julius Paelignus, invaded Armenia and ravaged the country, then under an Iberian usurper Rhadamistus. Rhadamistus had killed his uncle Mithridates, the legitimate king of Armenia, by luring the Roman garrison that was protecting him outside of the fortress of Gornea. Acting without instruction, Paelignus recognized Rhadamistus as the new king of Armenia. Syrian governor Ummidius Quadratus sent Helvidius Priscus with a legion to repair these outrages, but he was recalled so as not to provoke a war with Parthia.

Vonones II died in the same year, and was succeeded by Vologases I. Vologases I sought to continue the policies of the prominent former Parthian king Artabanus II (r. 12–38/41), and thus, one of his first objectives was to bolster the Parthian position in strategically and politically unstable regions that had served for decades as the source of war with the Romans. Thus he gave the kingship of Media Atropatene to Pacorus, and in 52 took the opportunity to invade Armenia, conquering Artaxata and proclaiming Tiridates I as king. Vologases felt his invasion was justified due to the recent usurpation of the Armenian throne by the Iberian prince Rhadamistus, which he saw as a violation of the former settlement made between the Parthians and Romans regarding Armenia.

A winter epidemic as well as an insurrection initiated by his son Vardanes forced him to withdraw his troops from Armenia, allowing Rhadamistus to come back and punish locals as traitors; they eventually revolted and replaced him with the prince Tiridates I in early 55. Rhadamistus escaped along with his wife Zenobia who was pregnant. Unable to continue fleeing, she asked her husband to end her life rather than be captured. Rhadamistus stabbed her with a Median dagger and flung her body into the river Araxes. Zenobia was not fatally injured and was recovered by shepherds who sent her to Tiridates. Tiridates I received her kindly and treated her as a member of the monarchy. Rhadamistus himself returned to Iberia and was soon put to death by his father Pharasmanes I of Iberia for having plotted against the royal power.

Visiting Rome

Prior to embarking for Rome in 66 AD, Tiridates I visited his mother and two brothers in Media Atropatene and Parthia. On his long trek he was accompanied by his wife and children and two of his brothers. His escort included an imposing retinue, comprising many feudal lords, several sages, 3,000 Parthian horsemen, and also a large number of Romans. Tiridates did not travel through sea, as he did not wish to pollute water, one of the seven Zoroastrian holy aspects. His route lay across Thrace, through Illyria, on the eastern shores of the Adriatic and Picenum, in northeastern Italy. The journey took nine months, and Tiridates I rode on horseback, with his children and queen at his side. The children of Vologases, Monobazes and Pacorus also accompanied Tiridates I.

Three Magi theory

It has been suggested that the visit of Tiridates I, an event that greatly impressed contemporaries, was adapted by Christians to become the story of the adoration of the Christ Child by the Three Magi. The Christian legend changed Rome into Bethlehem, the birthplace of the Ruler of the coming Kingdom of God, and replaced Tiridates I with that contemporary king who was already connected with Christianity through the Acts of St. Thomas: Gondophares, otherwise known as Kaspar.
