The Lucidarius, an anonymous medieval book, was the first German language summa,[1] written circa 1190–1195.
The text has a prologue in verse, while the body is in prose, in the form of a dialogue between a student and his master.
A printed version from Strassburg from around 1534 was specifically intended for Protestants and used information from Sebastian Franck's Weltbuch from 1534.
Translations of the book appeared in Dutch, Danish, Croatian and Czech.
[5] The same year another Augsburgian printer, Johann Bämler, also printed the book in a slightly different version, which was the source for most of the reprints of the next decades.
