Tyrannius Rufinus
The medieval Georgian sources relate that Nana had been a staunch pagan and despised Christian preaching until she was miraculously cured of a terrible disease, and subsequently converted, by a Cappadocian Christian missionary, Nino. The Roman scholar Tyrannius Rufinus, writing his history half a century after the Iberian conversion on the basis of the oral account of Bacurius the Iberian, also mentions an unnamed queen of the Iberians who was cured by a woman, a Christian "captiva". Through Nino's ministry, King Mirian was also converted around 337 and Christianity became an official religion in Iberia. Nana outlived her husband by two years and died, according to Toumanoff's chronology, in 363. She was canonized by the Georgian church. Nana and Mirian are traditionally considered to have been buried at the Samtavro convent in Mtskheta, where their tombs are still shown.
