Saint Walpurga
The canonization of Walpurga and the movement of her relics to Eichstätt occurred on 1 May in the year 870, thus leading to the Feast of Saint Walpurga and its eve, Walpurgis Night, being popularly observed on this date. She quickly became one of the most popular saints in England, Germany, and France. When the bishop had Saint Walpurga's relics moved to Eichstätt, "miraculous cures were reported as her remains traveled along the route". Miracle cures were later reported from ailing people who anointed themselves with a fluid known as Walburga's oil that drained from the rock at her shrine at Eichstatt.
