A few days ago I received the first part of Norbert H. Ott and Ulrike Bodemann, Katalog der deutschsprachigen illustrierten Handschriften des Mittelalters, which I mentioned under the topic of the Book of Lambspring. This catalogue issued in 1986 has a listing of the nine German manuscripts of the Buch der heiligen Dreifaltigkeit with illustrations, the six Splendor Solis, and a further 19 other manuscripts with illustrations are described. There are a number of interesting items of which I am unfamiliar so I will have to try and get copies made.
