Editing Johannes Aventinus (section)

==Historian of Bavaria==
In 1517, William appointed him as Bavaria's official historian and commissioned him to write a history of the country.<ref name="cathency">{{CathEncy|wstitle=Johannes Thurmayr}}</ref>  Many of the important authorities that Aventinus collected for this purpose have been preserved only in his copies. He embodied a critical treatment of them in a complete history of Bavaria, ''Annales Bojorum'' ("Annals of Bavaria"). His condensed German version of it, the ''Bayerische Chronik'', is the first important history in the German language.<ref name="cathency"/>
