What it is
The encyclicals and treatises of the one Greek bishop at Florence who refused to sign the union, on the filioque, purgatory, and the impossibility of agreement by formula.
Why it lasted
His refusal decided the outcome: the union collapsed in Constantinople, and he is honoured as a saint by the Orthodox church for it.
Where to read it
Public domain and free to read in full, though not held here. The archives below have it.
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.
