“This exceedingly simple outer life reflected a far more severe inner life. It was well known that Kyrillos slept little. But just how little is for the most part unknown. Each day he would awake at three in the morning for psalmody and Liturgy that would finish some five hours later. The entire day, until late, would be spent in meetings and visits, only to be interrupted by "his work" of Vespers at six in the evening. Most nights he would retire to his patriarchal cell just before midnight. This would allow for three to four hours of sleep at most. Yet even this is called into question. An examination of his letters (unpublished and thus unknown until now) reveals that if a time of writing as specific, then it was consistently between the hours of one to two in the morning. Even the few hours of sleep, it appears, would be regularly sacrificed.”
