Independently of Nickel, C. Scott Littleton developed a more elaborate version of the Sarmatian connection. Littleton first wrote about the theory with Anne C. Thomas in 1978, and expanded on it in a 1994 book co-authored by Linda Malcor, "From Scythia to Camelot". Littleton and Malcor argued that Artorius and the Sarmatian cavalry were the inspiration for King Arthur and his knights, but that many elements of Arthur's story derive from Caucasian mythology, ostensibly brought to Britain in the 2nd century by Sarmatians and Alans. They find parallels for key features of the Arthurian legend, including the Sword in the Stone, the Holy Grail, and the return of Arthur's sword to a lake, in the traditions of the Caucasus, and connect Arthur and his knights to Batraz and his Narts, the heroes of the legends of the North Caucasus.
