For this coming Tuesday (1/24), read the Beowulf, Blickling, and Alaimo. (The Alaimo is highly recommended, but not required.)
For next Tuesday (1/31), read the Ibn-Fadlan material (not actually by Ibn-Fadlan but by several other medieval geographers who have been anthologized with him) and the articles on the Canadian Arctic, and watch the Watt-Cloutier talk.
Have a great weekend.
