Collectio canonum in Verona, BC, LVII (55)
From Clavis Canonum
Verona, Biblioteca Capitolare, LVII (55) contains a collection of materials (including papal letters, namely of Celestine I) relating to Ephesos 431 only known from this manuscript. Maassen, Geschichte p. 727 pointed to similarity with the Collectio Turonensis but excluded mutual influence; he thought it possible that the Collectio Frisingensis I drew on the Verona collection and suggested a compilation still in the fifth century.
