Analyzing Ramandu's daughter as a "saintly mother", author Cathy McSporran contrasted her with the Lady of the Green Kirtle. She identified the latter, and all witches in "The Chronicles of Narnia" series, as embodying what Lewis characterizes as an "infernal Venus"; he coined this term in his 1942 book "The Screwtape Letters" to reference a female character who seduces a man to his death. McSporran defined Ramandu's daughter as the "natural opponent" of witches due to her innate goodness and beauty. According to McSporran, the character's maternal care for Rilian and ability to see through magical disguises are signs of her opposition to the Lady of the Green Kirtle.
