3. Old Low German or Old Saxon language. The oldest monuments of this language date back to the 9th century. The largest of them is the poem "Heliand" ("Savior"), which contains about 6,000 verses of biblical content. On the basis of the Old Saxon language, the middle-lower-German language was formed, in which the knightly literature of that time was written, namely the 13-14 centuries. In the course of further development, the lower German language did not develop into an independent language, but entered the national language as a dialect, which has the name "platdeutsch".
