Luke Knapke did not include the Prayers (1855, 64 pages) in his book. They they have been written later than 1900. They include a “Beichtspiegel” (confession mirror), a tool for the examination of one’s conscience, has this sentence: “Johannes Tauler   -   du häs dussen Bichtspiegel schriewen  -  dien Tied gaf’t noag kein Tngeltangel kein Kino un wat weit ik!” (Johannes Tauler   -   in your time there was no Tingeltangel and no cinema and search me!).
Tauler lived 1300-1361.  and Liwwät 1807-1881. About 1855 she could not know the German worgd Tingeltangel (low music hall or honky-tonk). About 1875 this word was created. The first cinema performance was in 1894 in New York. The confession mirror is a forgery, and the prayers are suspected also to be forgeries and plagiarisms.

Luke Knapke did not include the Ancient Poetry in his book. It is a collection of about 70 poems, written in Middle High German. The translations into High German were copied word for word out of an edition of German poems, published in 1969. (12e)
The translations are forgeries and plagiarisms.
