 Adalbert was sent by Pope Gregory V to convert the pagan Old Prussians to Christianity and had come to Prussia, apparently taking the route along the Vistula River to reach the Baltic Sea at „urbem Gyddanyzc“., which is identified with the later Gdańsk (Danzig).Then a small trading and fishing settlement with wooden buildings, it was anyway recorded by Canaparius as „urbs“, city.It is, however, now assumed by Johannes Fried, that the 'Vita' was not written by Canaparius, but was written down in Liège, with the oldest traceable version having been at the imperial Adalbert shrine at Aachen.
