Old Norse: Hrólfr, played by: Clive Standen
In Vikings, Rollo serves as a frenemy/adversary to Ragnar, his famous brother, only to end up becoming a French aristocrat. Part of this is even historically correct. Rollo was born either in Norway or Denmark around 860, i.e. five years before Ragnar’s possible death, was a Viking, and became the first ruler of Normandy (“the Land of the Northmen”). As Snorri’s Heimskringla mentions, when he grew up into adulthood his name was extended to Göngu-Hrólfr, “Rollo the Walker”, since he became too heavy to be carried by a horse. Remembering that Heimskringla is a Saga, I would also assume that he was the most handsome, wise, and brave of all the men who were too large to ride any horse.
Rollo is possibly the most… adapted of all characters in Vikings. First of all, there’s the problem of Ragnar and Rollo being brothers, despite the fact that Rollo was born in 860, when Ragnar was at least in his sixties. Second, I am almost certain I saw the TV Rollo on a horse. Third, we know for a fact that he existed, but in this particular case unpacking the differences between history and History could fill a book three times as long as this one.
The earliest historical event noting Rollo’s existence is his leadership over the Vikings who laid siege to Paris in 885-886. At this point I already get a headache, because it immediately throws the chronology of Vikings off the cliff. The series depicts Ragnar, Rollo, the invasion of Paris, Rollo’s marriage and subsequent leadership of the French, glossing over the fact that Paris was invaded twenty years after Ragnar had died.
