monasteries and stupas. Wilhelm Geiger was one of the first Western scholars to suggest that it was possible to separate useful historical information from the mythic and poetic elaborations of the chronicle. While other scholars had assumed that the Mahavamsa had been assembled from borrowed material from Indian Pali sources, Geiger hypothesized that the Mahavamsa had been based on earlier Sinhala sources that originated on the island of Ceylon. While Geiger did not believe that the details provided with every story and name were reliable, he broke from earlier scholars in believing that the Mahavamsa faithfully reflected an earlier tradition that had preserved the names and deeds of various royal and religious leaders, rather than being a pure work of heroic literary fiction. He regarded the early chapters of the Culavamsa as the most accurate, with the early chapters of the Mahavamsa being too remote historically and the later sections of the Culavamsa marked by excessive elaboration. Geiger's Sinhala student G. C. Mendis was more openly sceptical about certain portions of the text, specifically citing the story of the Sinhala ancestor Vijaya as being too remote historically from its source and too similar to an epic poem or other literary creation to be seriously regarded as history. The date of Vijaya's arrival is thought to have been artificially fixed to coincide with the date for the death of Gautama Buddha around 543 BCE. The Chinese pilgrims Fa Hsien and Hsuan Tsang both recorded myths of the origins of the Sinhala people in their travels that varied significantly from the versions recorded in the Mahavamsa- in one version, the Sinhala are descended from naga or nature spirits who traded with Indian merchants, and in another, the Sinhala progenitor is a prince exiled for patricide who then slays a wealthy merchant and adopts his 500 children. The story of the Buddha's three visits to Sri Lanka is not recorded in any source outside of the Mahavamsa tradition. Moreover, the genealogy of the Buddha recorded in the Mahavamsa describes him as being the product of four cross cousin marriages. Cross-cousin marriage is associated historically with the Dravidian people of southern India- both Sri Lankan Tamils and Sinhala practiced cross-cousin marriage historically- but the exogamous marriage was the norm in the regions of northern India associated with the life of the Buddha. No mention of cross-cousin marriage is found in earlier Buddhist sources, and
