The saints behind the name
Mariamne the Equal-to-the-Apostles
February 17, Apostle, Μαριάμνη
St. Mariamne was the sister of the Apostle Philip and shared in his preaching together with the Apostle Bartholomew, travelling through Asia Minor and enduring persecution at Hierapolis. After her brother's martyrdom she continued to preach in Lycaonia.

Mary of Egypt
April 1, Holy Woman, Μαρία η Αιγυπτία
St. Mary of Egypt is the great example of repentance. Living in Alexandria in the fifth and sixth centuries, she spent her youth in sin; traveling to Jerusalem, she was held back from entering the Church of the Holy Sepulchre by an unseen power, and, praying before the icon of the Theotokos, she was converted. Crossing the Jordan, she lived some forty-seven years alone in the desert in fasting and prayer.

Dormition of the Theotokos
August 15, Great Feast, Κοίμηση της Θεοτόκου
The Great Feast of the Dormition commemorates the falling asleep of the Most Holy Theotokos. According to tradition, the Apostles were gathered from the ends of the earth to her bedside in Jerusalem, where she gave her soul into the hands of her Son; her body was laid in a tomb in Gethsemane and was found to have been taken up, for the Mother of Life was translated to life.
