He collected the humorous tales surrounding the "Priest from Kahlenberg" (Pfaff vom [or von] Kalenberg), published with a frame story in verse form as Des pfaffen geschicht und histori vom Kalenberg.
[1] The work was very popular, reprinted well into the 17th century, with translations to Low German, Dutch and English.
The figure of the "priest from Kahlenberg" is also mentioned in the Ship of Fools by Sebastian Brant and in the Till Eulenspiegel chapbook.
The figure also inspired the modern narrative poem Der Pfaff vom Kahlenberg by Anastasius Grün (1850).
[2] Gundacker von Thernberg is recorded as parish priest in Kahlenbergerdorf, a village north of Vienna, for the period of 1339 to 1355, and later in Prigglitz, Lower Austria, where his name has been found on the fragment of a tombstone.
