Kassel conversations
Kassel conversations () is the conventional name of an early medieval text preserved in a manuscript from c. 810. It is held today in the university library of Kassel, Germany (Ms. 4° theol. 24). It contains several parts, among them an "Exhortatio ad plebem christianam", an instructional theological text in Latin. The part that has been of most interest for modern scholarship is that of the so-called Kassel glosses, one of the earliest written documents of the Old High German language. The Kassel glosses are a collection of words and short phrases translated from Latin to Old  High German. They appear to have been meant as a practical tool to help speakers of Romance languages to learn Old High German. Among them are everyday phrases such as orders given to servants "("shave my beard")," questions and answers for basic communication ("do you understand? No, I don't"), and a few fragmentary grammar paradigms ("I understand, you understood, we understood"). The most famous entry, however, is a jocular jibe in Latin and Old High German: The manuscript is written on 60 sheets of parchment. Based on the scribal hands and the forms of the Carolingian minuscule employed, it  is believed that the text was written by two different scribes from the area of Regensburg c. 810. Parts of the text have a parallel in a second manuscript held in St. Gallen, Switzerland. The manuscript came to Kassel from Fulda in 1632. It was mentioned for the first time by Johann Heinrich Hottinger in his work "Historica ecclesiastica novi testamenti" from 1637. The first scholarly study of the manuscript was done by Wilhelm Grimm in 1846. Grimm made the mistake of re-drawing the text with a modern ink to make the writing more legible. This has caused some  permanent damage to the fragile material.
