Luther's Prayer to St. Ann

Not too many know this but during the thunderstorm in which he swore to God about becoming a monk, that Luther also prays a prayer to St. Ann, mother of Mary to deliver him from the thunderstorm.  Luther does change his approach about the prayers to saints later and it is addressed in his 95 thesis. He states that the saints do not intercede before Jesus but rather we can go directly to him in prayer.
