The Prince of Hoby: Roman Ally? Or Evidence of a Roman Invasion of Denmark?

In 1920, at what became the archaeological site of Hoby, on the Island of Lolland, Denmark, the Hoby Treasure was discovered. Further excavation revealed not only a rich grave site, but also a wealthy village nearby, one which was unusually fortified and prosperous for the region. The presence of Roman artifacts, coupled with textual references to some sort of military activity in the North Sea and baltic, has led Danish archaeologists to speculate that whoever this individual was that was buried in the Hoby grave, was a Roman ally, or possibly a part of a broader military action concerning Southern Scandinavia.
