Lyndal Roper,
Martin Luther: Renegade and Prophet (New York: Random House, 2017), p. 52:
On the way back, the two Augustinians stopped at Augsburg, where, Luther
recalled, he was taken to meet the holy Anna 'Laminit', or 'leave me not'. The
daughter of simple craftspeople, she was believed to live miraculously without
eating. This kind of religiosity — or what modern writers have termed 'holy
anorexia' — was a powerful streak in late medieval devotion, encouraged by an
extreme asceticism that regarded bodily appetites as inimical to religious
perfection. Female saints in particular might fast to extremes and undergo
mystical experiences. In a church which was deeply distrustful of women,
asceticism offered them an avenue of expression and authority. Laminit
reported visions of St Anna, her name saint and the saint to whom we know
Luther himself was attached. Not only did she go without food, she was famed
as passing neither water nor stools.
Id., p. 53:
She was unmasked soon after by the duchess of Bavaria, who discovered her secret
stash of luxury food, such as pepper-cakes and pears; it turned out that she
emptied her stools out of the window.
