Collectio Laureshamensis
The Collectio Laureshamensis takes it name from the medieval home of Città del Vaticano, BAV, Pal. lat. 574 at Lorsch. For a long time, this was the only known copy extant, but another copy is extant in Gotha, Forschungsbibliothek, Memb. I 85. The collection is chronologically arranged.
Città del Vaticano, BAV, Pal. lat. 574 (as described by Maassen, Geschichte p. 586-590) contains a capitulatio with 32 numbered entries; according to Maassen, this part of the collection is the original core of the Laurenshamensis (Geschichte p. 590). However, the Gotha manuscript (unknown to Maassen) contains the same additions also found in the Vatican manuscript. The Decretum Gelasianum found in the Gotha manuscript may also have been part of the Vatican manuscript in medieval times. So whatever the "original" Laureshamensis looked like, the enlarged version had a circulation of its own.
