The more than two dozen Rai languages in eastern Nepal, which make up the larger part of the Kiranti language family, are linguistically highly varied. Due to this, intergroup solidarity has been relatively weak, and Rai ethnicity must be seen as constructed in recent history. However, it is striking how the mythological narratives of these different Rai 'subtribes' - oral stories about the origins of culture and the deeds of the ancestors - form a strong and coherent tradition in which the different variants of episodes possess an obvious 'family resemblance'. This mythological tradition is clearly distinct from those of the neighboring Limbu, the other major Kiranti group. This volume, which includes introductory chapters to Rai mythology and Rai grammar, for the first time brings together different variants of myths from various Rai languages, presenting them with linguistic glossings in interlinear translations. This makes it possible not only to study the myths and their cultural meanings as oral texts but also to compare narrative structures across different grammars. The book is of special interest for linguists, anthropologists, and folklorists with a focus on the Himalayas.
