Blue Annals

The Blue Annals, completed in 1476, written by Gö Lotsawa Zhönnu-pel (, 1392–1481), is a Tibetan historical survey with a marked ecumenical (Rimé movement) view, focusing on the dissemination of various sectarian spiritual traditions throughout Tibet.

An English translation by George de Roerich with help from Gendün Chöphel was published in 1949 and has since remained one of the most widely consulted sources on the history of Tibetan Buddhism up to the fifteenth century.

The Tibetan and Himalayan Library is working on a new online translation of the Blue Annals.

A similar work from a later period is Tuken Lozang Chö kyi Nyima's Crystal Mirror of Philosophical Systems completed in 1802. Tuken favored the Gelug school, but he nonetheless provides broad and useful historical information, relying heavily on the Blue Annals himself.

Etymology
The term Blue Annals or Bamboo History was a word found in the Tang dynasty poem by Du Fu (722–770) 唐·杜甫《赠郑十八贲》诗：“古人日以远，青史自不泯. ” translating as, "The ancients' times are long gone, but their names carved on bamboo remain fresh." The word is also found in the famous Chinese novel Romance of the Three Kingdoms, a work that is estimated to have been completed in 1367. The original sentence reads 《三国演义．第三十六回》：「愿诸公善事使君，以图名垂竹帛，功标青史. 」An excerpt from the thirty-sixth chapter of Three Kingdoms, this translates as, "May all your public and good deeds make your lordship hang down bamboo and silk with your name, and your achievements make their mark on history."
