Super arboribus consanguinitatis et affinitatis et affinitatis et cognationis spiritualis
CCCC MS 151 contains a number of theological and ecclesiastical texts copied in a number of workmanlike hands of the middle years of the fifteenth century. Among the material that can be identified are the Processus iudiciarius of Iohannes Auerbach (fl. 1406-22), Iohannes Andreae (Giovanni d'Andrea) (c. 1270-1348) Super arboribus consanguinitatis et affinitatis et cognationis spiritualis and François de Meyronnes OFM (d. after 1328) De indulgentiis. It also contains a tract on tithes widely attributed to Andreas Didacus de Escobar (c. 1357-1427), Tractatus decimarum (De decimis). These treatises contain much that would interest Parker the ecclesiastical reformer, notably Giovanni d'Andrea's tract on the prohibited degrees of consanguinity, a subject that occurs not infrequently in Parker's own papers in the collection. The provenance of the manuscript and how it came to be in Parker's possession are unknown.
