Edited sentence: In sixteen books, written in Latin on the invitation of Archbishop Absalon, it describes Danish history and to some degree Scandinavian history in general, from prehistory to the late 12th century.It is told in a sparkling and entertaining language, that reads as well currently as it did back then.The last three books (14-16), telling about Danish conquests on the south shore of the Baltic Sea and wars against the Slavs (see Northern Crusades), are very valuable for the history of West Slavic tribes (Polabian Slavs, Pomeranians) and pagan Slavic religion.The sixteen books, in prose with an occasional excursus into poetry, can be categorized into two parts, book 1-9 being what is known as the Old Norse part and Book 10-16 being medieval history.When the book was written, and in what order the books were written, is a matter of historical interpretation
