What is "lawspeaker"

A lawspeaker or lawman ( Swedish: lagman, Old Swedish: laghmaþer or laghman, Danish: lagmand, Norwegian: lagmann, Icelandic: lög(sögu)maður, Faroese: løgmaður, Finnish: laamanni) is a unique Scandinavian legal office. It has its basis in a common Germanic oral tradition, where wise men were asked to recite the law, but it was only in Scandinavia that the function evolved into an office. Two of the most famous lawspeakers are Snorri Sturluson and Þorgnýr the Lawspeaker.
