One of the daughters of men, beloved by one of the sons of God. The angel who loved her ranked with the least of the spirits of light, whose post around the throne was in the uttermost circle. Sent to earth on a message, he saw Lea bathing and fell in love with her; but Lea was so heavenly-minded that her only wish was to dwell in purity, and serve God in singleness of heart. Her angel lover, in the madness of his passion, told Lea the spellword that gave him admittance into heaven. The moment Lea uttered that word her body became spiritual, rose through the air, and vanished from his sight. On the other hand, the angel lost his ethereal nature, and became altogether earthy, like a child of clay. (Moore: Loves of the Angels, story 1.)
