Gnel also known as Gnelus (flourished 4th century - died August, 359) was a Prince from the Arsacid dynasty of Armenia.
Gnel was the son of Tiridates by an unnamed mother, hence his paternal uncle was Arsaces II (Arshak II) who ruled as Roman Client King of Armenia from 350 until 368 and was a grandson to the previous ruling Roman Client Armenian King Tiran (Tigranes VII) who ruled from 339 until 350.
Gnel was most probably born and raised during the reign of Tiran. Sometime during the reign of his paternal grandfather, the Sassanid King Shapur II launched a war on Rome and her allies, firstly by persecuting the Christians that lived in Persia and Mesopotamia. Shapur II’s war by capturing these territories began to dealt a severe blow to Roman prestige in the East. Eventually the Sassanid King with his army had invaded Armenia, taking the members of the royal family including Gnel as hostages as they were betrayed to Shapur II by Tiran’s chamberlain. Gnel with all members of his family had become Sassanid political prisoners in which his paternal grandfather was blinded and thrown into prison after Shapur II accused Tiran of collusion with Rome.
The nobles of Armenia were infuriated by the brutality of Shapur II and his treatment of the Armenian royal family, took up arms and fought against Shapur II and his army with assistance from the Romans. They successfully drove Shapur II and his army out from Armenia. After Shapur II was defeated, he had signed a treaty and Gnel with members of his family were released from prison. As Tiran being depressed and blinded from his experience in captivity, had abdicated his throne and Arsaces II succeeded Tiran as Armenian King in 350.
During the reign of Arsaces II, Gnel was a popular prince in Armenia and could have been seen as a potential successor to his uncle. The below surviving inscription reveals the popularity of Gnel; his high standing within the Arsacid dynasty and within Armenian society:
Sepuh means in Armenian nobleman or gentlemen. From the inscription it appears that Gnel was designated a royal title within the context of the local aristocracy and feudal system and also appears that his royal title was denoted to all members of great families in Armenia other than the family heads.
