A complex miscellaneous collection of astronomical and computistical texts, tables and diagrams, including the Computus Helperici (incomplete; 1r-10v). For a description of the highly heterogeneous contents, see especially Cordoliani 1955 and Borst 2006: I, 249–50.

• Certainly not written in Brittany
• Some contents certainly derive from a Breton exemplar / archetype

The date and the Provençal origin of this MS are revealed by an informative colophon occurring at fol. 117v, mentioning the name of the scribe, Arnulfus, and that of the powerful countess of Provence Adélaïde-Blanche of Anjou (Adalax comitissa). Nonetheless, it is likely that at least some of the contents of Madrid 9605 derived from a line of transmission leading to Brittany, as shown by the occurrence of one Old Breton gloss at fol. 69r (sterdigkiniat, literally meaning 'star-soothsayer', gl. Lat. astrologus), as well as by numerous textual matches with a group of MSS that includes the Breton computistical collections in Angers, BM, 476 and Paris, BnF, Lat. 6400B, as argued in Bisagni (2020b). Interestingly, this MS also present numerous parallels with the contents of the so-called 'Bobbio Computus', i.e. Milan, Biblioteca Ambrosiana, H 150 inf. (probably written in a Northern Frankish scriptorium, in spite of its traditional name, around AD 826). For another 11th-century manuscript from southern France (also possibly from Avignon) presenting materials of probable Breton origin, see the entry concerning Rome (Città del Vaticano), BAV, Barb.lat.477.
