Next up as promised, here is the list of my primary source research books used in the writing of THE TIME OF SINGING. I don't read Latin, but I can have a good guess at some of the gist when it isn't in translation - although obviously it's a boon when a translation is available. All of the below material is from sources around at the same time as my characters, so I feel they give me an immediate handle into their world and one that I can interpret for myself at first hand, rather than have it go through the filter of later opinion.
Not in any order:
Jocelin of Brakelond: Chronicle of the Abbey of Bury St. Edmunds.
Histoire de Guillaume le Mareschal, vols 1 and 2 - Anglo Norman Text Society
Richard FitzNigel - Dialogus de Scaccario - Oxford Medieval texts
Constitutio Domus Regis - Oxford Medieval Texts
The Treatise on the Laws and Customs of the Realm of England Commonly Called Glanvill - edited and translated by G.D.G. Hall - Oxford Medieval Texts
The Church Historians of England vol 1V part 1. The Chronicles of Melrose and Jordan Fantosme's Chronicle
The Great Roll of the Pipe for the 9th Year of Richard I. Click on the picture below for a larger image and you should be able to see an example of the pleas my hero Roger Bigod was hearing in Yorkshire in this period during his term as a royal justice on the itinerant circuit.
Feet of Fines for the 7th and 8th years of the Reign of Richard I - Pipe Roll Society
Feet of Fines for Norfolk and Suffolk 1199 - 1215
Pipe Roll Society
Court, Household and Itinerary of Henry II - collated and translated by the Rev. R. W. Eyton.
Roger of Wendover's Flowers of History volume 2 part 1. 1170 - 1215 AD
That's about it I think, although there may be one or two others lurking in forgotten corners. Next time round I'll list the political and social history sources that haven't fitted into these first two categories.
