Early Life and Apostasy
Constantine was born on the island of Hydra during the period of Ottoman rule to parents named Michael and Marina, described in the sources as devout Orthodox Christians who raised him in the faith and in love for Christ and country. The poverty and scarcity of work on the island prompted him, at the age of eighteen and despite his mother's objections, to travel to Rhodes seeking a livelihood.
On Rhodes he found employment with Hassan Kapitan (also rendered Hasan Kapetan), the Turkish governor, grooming the governor's horse and carrying out various duties. At a large public gathering Constantine was made drunk, and Hassan Kapitan then had the Hodjas perform a circumcision on him and placed a white turban on his head, giving him the Muslim name Hassan. When he returned home and sought his mother, she refused to open her door, saying, in substance, that she had no son named Hassan. He spent approximately three years in this condition, living outwardly as a Muslim while inwardly grieving his apostasy, giving generous alms to Orthodox believers, weeping in private, and showing reverence to Orthodox clergy.
