Now that the rain has stopped, I'm feeling ambitious. I'm going to try adding a new feature: Pseudo-Isidore In His Own Words.
On this page I plan to collect all the Latin passages that our forgers seem to have composed themselves -- passages that nobody can tie down to any sources. What exactly to do with all these passages, I'm not sure. But they seem potentially useful.
For now, you'll see that Pseudo-Isidore freely composes large chunks of the prefatory material. These passages will get rarer as we go on, though.
