Letter to Unknown
p148“The angel was not weary of waiting for Gunhilde, till she had unravelled her mesh of thought, and seeds of mercy, of purification, were planted in the breast.”
Fuller, Margaret. The Letters of Margaret Fuller. Edited by Robert N. Hudspeth. Vol. VI. Ithaca: Cornell University Press, 1988.
Inferred Fuller alludes to the Gunhilde legend—a nun seduced by her confessor who flees her convent, only to discover that an angel took her place during her absence—without naming her source.
Hudspeth traces it to Karl Simrock's Rheinsagen, which Fuller reviewed and translated from in her essay "Romaic and Rhine Ballads." Fuller applies the legend as a personal spiritual metaphor: "The angel was not weary of waiting for Gunhilde."
