Noteworthy also, is a story written down by Adam of Bremen in his "Gesta Hammaburgensis ecclesiae pontificum" (Deeds of Bishops of the Hamburg Church) from 1075/6 about a certain foreigner called "Hericus", who was slain and martyred while preaching among the "Sueones". Adam had heard the story from King Sweyn II of Denmark. According to some historians, resemblance to later legend about an English-born "Henricus", who was allegedly slain and martyred in Finland, is too striking to be a coincidence.
