Monastic Life as Smaragdus
Advised that disguise would let her escape her impending marriage, Euphrosyne entered the monastery claiming to be a eunuch. By one account she presented herself to the abbot as 'a eunuch of Emperor Theodosius,' adopting the monastic name Smaragdus.
Under the spiritual guidance of the monk Agapitus, she is said to have excelled in ascetic practice, surpassing the other monks of the community in fasting and prayer. When dissension later arose in the community over her beauty, she withdrew to a solitary desert cell, keeping contact thereafter only with her spiritual director and the abbot.
