That many of the things we thought we knew about the Vikings is wrong was revealed to us in our Five Books interview about the Vikings with medieval historian Eleanor Barraclough in 2016. With our interest in Vikings awakened, it was exciting to see a book called River Kings: A New History of the Vikings from Scandinavia to the Silk Roads published in February 2021. River Kings is by archaeologist Dr Cat Jarman, who is a senior adviser to the new Museum of the Viking Age in Oslo. Specifically, she is a bioarchaeologist, which means she uses forensic tools—like isotope analysis, carbon dating, and DNA analysis—to try and figure out what happened to bodies buried more than a millennium ago. The book is absolutely mesmerizing, both about the techniques she deploys, and the story she tells about the Viking skeletons she uses those techniques on.
