Book excerpt: In its ports, we find a priceless cargo of information; here are the first foreign descriptions of tea and porcelain, a panorama of unusual social practices, cannibal islands, and Indian holy men--a marvelous, mundane world, contained in the compass of a novella. In Mission to the Volga, we move north on a diplomatic mission from Baghdad to the upper reaches of the Volga River in what is now central Russia. This colorful documentary by Ibn Fadlan relates the trials and tribulations of an embassy of diplomats and missionaries sent by caliph al-Muqtadir to deliver political and religious instruction to the recently-converted King of the Bulghars. During eleven months of grueling travel, Ibn Fadlan records the marvels he witnesses on his journey, including an aurora borealis and the white nights of the North. Crucially, he offers a description of the Viking Rus, including their customs, clothing, tattoos, and a striking account of a ship funeral.
