“ By the end of the twelfth century the saint had become one of the most widely revered in Europe. At Cologne a famous church, served first by nuns and afterwards by canonesses, rose on the site of the discoveries, which by an extension of the city became included within its walls. This church still contains the tomb of St. Ursula and a wonderful collection of relics of the virgin-host (see Vill, Wegweiser zur Kirche der heiligen Ursula in Köln) . Relics were scattered throughout Europe with a lavish hand until Boniface IX (d. 1404) forbade further translations of them. ”
