The volume is the third stage of a wider project of commentary and translation of Snorri Sturlson’s Heimskringla, the best known of the old Norse king’s sagas. Francesco Sangriso, its curator, delves here into the Haralds saga gráfeldar, which is a sort of stand-alone in the general structure of the Heimskringla, because it is not focused on a single character, but rather on several historical figures, whose role will expand in the ensuing Olaf Tryggvason’s saga. The importance of this book actually spans well beyond the Norse boundaries and embraces the whole Baltic region, as Sangriso correctly points out.
