Captivity and Trial of Chastity
By the accounts handed down in his life, Moses was a tall and handsome man, and during his captivity he attracted the attention of a wealthy Polish widow who was taken with him and wished to make him her husband. She ransomed him from captivity despite his refusal, but he firmly rejected her advances, declaring that he would become a monk.
The synaxarion relates that, when he persisted in his refusal, the widow had him severely beaten with iron rods until the ground was soaked with his blood, and ordered that he be struck daily; the accounts further state that he was emasculated for the sake of his purity. According to these accounts an Athonite hieromonk tonsured him as a monk during his captivity. After the death of Boleslav and a rebellion in Poland, the widow perished and Moses was freed.
