880 ELDAD HADANI (the Danite)
Claimed to belong to the ten lost tribes who lived near Ethiopia and the river Sambatyon. According to legend, the river threw up stones all week long and rested on the Sabbath. The lost tribes were therefore doomed to remain forever on the other side of the river, since on the day when the river was still they observed the Sabbath and therefore could not cross. Eldan maintained that the lost tribes observed certain ritual differences and had an Oral Law of their own, given by Moses and Joshua. Although he was not generally believed, he helped rekindle hope that salvation was near. His tales were printed in 1480.
