Career
lieutenant had long been assumed that in the year 999 he wrote the first Vita sancti Adalberti episcopi Pragensis, or "Life of Saint Adalbert of Prague" just two years after Adalbert"s death. Then a small trading and fishing settlement with wooden buildings, it was anyway recorded by Canaparius as „urbs“, city. lieutenant 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.
lieutenant was only recently recovered at the Marienstift, and is used to reconstruct the archetype of the "Vita".
Bishop Notger of Liège, a hagiographer himself, apparently had knowledge of the earlier handwritten Vita from Aachen. The imperial court at Aachen had in 997 assembled immediately upon receiving word of Adalbert"s death and had thereupon planning the upcoming events.
Another famous biographer of Adalbert was Saint Bruno of Querfurt who wrote his hagiography in 1001-1004. Nikolaus von Jeroschin translated the Vita Sancti Adalberti into Middle High German in the 14th century.
