Cassian

Venerable Cassian (Cassiane) was the sister of Saint Eutychius, bishop of Gortyna, and of Saint Eutychian, the venerable martyr, in Crete. Local tradition, attested in the tenth century by Venerable John the Stranger of Sivas, says that the three siblings practised asceticism in the Asterousia mountains in the time of the Arab persecution. Cassian lived as an ascetic in a cave in a steep place, on the promontory of Lithino or Kefali, called the "cave of the Nun". After her brothers' deaths she buried them in a cave which is today a chapel of the Odigitria Monastery, in honour of the three holy siblings.

The names of the three appear in no episcopal list, and placing them in the persecutions of the early centuries has no basis; the only reliable source is the local tradition. She is commemorated on 17 August, in the calendar of the Church of Greece (new style), together with her brothers.
