Opus Tertium, Opus Minus, Compendium Philosophiae
Only partial translations or excerpts exist. This is the first complete English translation.
While Roger Bacon's 'Opus Maius' has been translated into English (by Robert Belle Burke), the 'Opus Tertium', 'Opus Minus', and 'Compendium Philosophiae' (often identified with the 'Compendium Studii Philosophiae') have never received a complete English translation. Only fragmentary excerpts or partial sections (such as A.G. Little's 1912 translation of a portion of the 'Opus Tertium') exist in English scholarship. The 'Compendium Studii Theologiae' has been translated by Thomas S. Maloney, but it is a distinct work from the 'Compendium Philosophiae'.
