Opera hactenus inedita, Fasciculus 15
No prior complete English translation of this text has been found.
The work 'Opera hactenus inedita' is a multi-volume series edited by Robert Steele (and others) containing various Latin texts by Roger Bacon. 'Fasciculus 15' refers to a specific volume in this series (likely 'Summa Grammatica' or similar, published around 1935, though the prompt specifies 1909). My searches confirm that while the series exists, there is no evidence of a complete or partial English translation of the specific Latin text contained in Fasciculus 15. The search results for 'Opera hactenus inedita' generally point to the Latin editions themselves, not English translations of the contents.

Roger Bacon forces a collision between the rigid rules of Latin grammar and the messy reality of human intention. You will discover why a grammatically perfect sentence can fail to convey meaning, while a deliberate error can be the most accurate way to speak.
