15 December - Christiane, or Nina, or Ninon, or even Nune was born in Colastri in Cappadocia. Her real name is not clear but these names were given to her by the people of Georgia because she preached Christianity: Christiane as a disciple of Christ. Nina is a contraction of Christiane, while Nune is an appellation for nuns.

According to tradition, she would be a captive sold to the royal palace. She lived in Mtskheta, today Tbilisi. Christiane devoted herself to prayer and was considered a shaman, but she was still respected by the Georgians. One day the queen was very ill, at the point of death, and Nina healed her. The queen offered her many gifts and gold as a reward, but she refused, her only desire being the conversion of the queen and for her to turn to God. The queen converted to Christianity, as did the king, her husband, and the subjects of the kingdom. The king asked the Patriarch of Constantinople to send a bishop to his kingdom, while Nina went to live as a hermit. A cathedral now stands over her tomb. The Church of the East also venerates this saint on January 14 and she is considered the apostle who proclaimed the Gospel in this part of Georgia.
