Polyptiques and Polyptycha

For a while, I was all about monastic administrative documents of the early Carolingian era, and during this time I had acquired a cool book

• Dieter Hägermann, Das Polyptychon von Saint-Germain-des-Prés: Studienausgabe, Köln-Weimar-Wien (Böhlau) 1993.

and located the cool website of the University of Leicester, which provides an overview of the existing polyptiques, Latin texts and English translations; cf the example of Weissenburg.

A similar intention lies behind the cartularies, and here the book I acquired was

• Constance Brittain Bouchard, The Cartulary of Montier-en-Der, 666-1129, Toronto (University of Toronto Press), 2004.
