The explanation for this lies in the writer's approach to history: That there is a certain amount of truth contained in the text is corroborated by numerous carvings, edicts and monuments still extant in Sri Lanka today – e.g., Parakramabahu's wars with Gajabahu II and Manabharana are attested to by at least one rock-carving from this period. Furthermore Geiger also believes that the Culavamsa 'does not consciously relate ... false [information]'. The primary source for Parakramabahu's reign is the Cūḷavaṃsa. Translation The foremost translation of this work was that of Wilhelm Geiger from Pali into German, completed in 1930. This was subsequently translated into English by Mabel Haynes Bode, and the English translation was revised by Geiger. In 1929 an English edition was published by Oxford University Press, translated by C. M. Rickmers. The British colonial government commissioned a translation into English of the Cūḷavaṃsa in 1871 and published it alongside George Turnour's translation of the Mahavamsa. Continuations and related works In 1871, the British colonial government of Sri Lanka commissioned a 101st chapter of the Cūḷavaṃsa, covering the period from 1815-1871. In 1935, Yagirala Pannananda, a Buddhist monk, wrote Mahavamsa Part III, a further extension of the Cūḷavaṃsa, in Sinhala. While not authorized by any government agency or religious organization, it was eventually accepted as part of the larger Mahavamsa/Cūḷavaṃsa tradition. In 1977, the government of Prime Minister JR Jayawardene established a commission to extend the chronicle to cover the years 1935-1977.
