Legacy import had fused this Spanish dissertation with Masaniello Parise's fencing treatise. The two items are now separated, and this surviving record retains only the Pareja/Pareja-cluster witness. Type reviewed on August 6, 2026 after renewed source search. No direct external bibliographic witness was confirmed beyond indirect local notes and the Thimm-derived manuscript description, so this record is conservatively treated as a manuscript rather than a bibliography. Author, date, and title still require stronger external confirmation.
