The Medieval Church · c. 1257
The Breviloquium
Bonaventure · 1221–1274
What it is
A compact summary of the whole of theology in seven parts, written for students who found the full commentaries impossible.
Why it lasted
The clearest short statement of medieval theology by anyone, and the best single entry point into the Franciscan tradition.
Where to read it
This work is in the public domain and can be read in full, free, at the archives below. The Library catalogues it; it does not host the text.
These open a search on each archive rather than a direct link, which is the honest way to point at an edition nobody here has checked line by line.
