There is a long standing tradition among some cultures that on the eve of Saint Agnes, January 20, a young girl could learn of her future husband. For example, in England a girl would take sprigs of thyme and of rosemary, sprinkled them three times with water, put one on each side of her bed, and then recited: “Saint Agnes, who’s to lovers kind - Come ease the trouble of my mind.”
She would then see in her dreams the face of her future husband.
