Another trawl through the archives to see how British TV has presented the history of the Vikings.
Alice Roberts host this edition, which sees the Vikings being depicted originally as brutal and violent in the 1960s, before moving onto more sympathetic depictions in the 1980s, and later an examination of their legacy to the modern world.
Among the programmes featured in this show include one presented by Magnus Magnusson, clearly proud of his Icelandic ancestry.
The Vikings: Foe or Friend? A Timewatch Guide is on BBC Four at 21.00.
