Oxford does not have a dictionary of Medieval Latin. They do have a dictionary of Medieval Latin from English sources. There are dictionaries with German and French sources. Time and place do matter in translating Medieval Latin. It is a bit of a shock to me. I thought it might be fun for a summer project to read Walter Map's De Nugis Curialium in the original latin or Gesta Francorum.
The Bodleian Library, which owns the only manuscript of De Nugis Curialium, jealously guards it. I could shell out $170 American for their book. This is better than the version I saw on Amazon last year that was going for close to $300. At the same time, Gesta Francorum is on Latin Library for free. Gesta Francorum features one of my favorite characters - Bohemond of Taranto, the studmuffin, who , if a movie is ever made of the First Crusade featuring him, should be played by Brad Pitt. That movie should be made soon before Brad gets too old.
Gestae Francorum it is. Chapter One, Book One will be posted tomorrow. It is already done as best as I can.
And I think a link to Latin Library is in order.
