||Notes from Snow 1977, no. 131: "The subject is treated in great detail and with vast erudition by G. The theme of the Virgin Mary substituting for errant nuns goes from the earliest Latin accounts recorded through 1927. Cotarelo y Valledor's study of 1904 is dwarfed in comparison. CSM 94 and 55 are dealt with (pp. 111-15), the first as a fused and the second as a contaminated version but both unique in the thirteenth century, and, Guiette claims, with genuine élan and artistry. CSM 285, on a related theme, is given briefer mention (p. 175)."
