He is best known for his work, Gesta Danorum, which chronicles the history of Denmark from its legendary origins to the author's own time. This text is significant for its blend of history, mythology, and folklore, providing valuable insights into early Scandinavian culture. Saxo's writings are considered one of the earliest comprehensive accounts of Danish history and have influenced later historians and writers. His work also includes references to figures from Norse mythology, making it an important source for understanding both historical and mythological narratives in the region.
