In the conclusion the Ahmad ibn Fadlan series, ibn Fadlan encounters the Rusiyyah, recounts the famous Viking funeral, and is disgusted by a communal wash basin. I also talk about the text itself.
Our 10th century traveller, Ahmad ibn Fadlan, settles in among the Bulgars, develops a distaste for their fish-oil based food, and is terrified by events in the sky.
Ahmad ibn Fadlan travels from early 10th century Baghdad on a diplomatic mission to the Volga Bulgars. There is a Viking funeral in his future, along with unfamiliar cultures and extremely cold weather. It's not The 13th Warrior, which it loosely inspired, but it is a good story.
