Inferred L3 evidence-packet article.
This article describes an entity that is not directly attested. It is an inference from the evidence listed below.
Summary
Source-backed inferon that Codex Faenza preserves anonymous intabulations across original and Bonadies layers.
What is being inferred
That the anonymous pieces of Codex Faenza 117 - forty-two of its sixty-eight compositions - are not scattered accidents but constitute a describable repertory organized in two codicological layers: the original corpus of instrumental intabulations of fourteenth-century vocal works, and the fifteenth-century additions entered by Johannes Bonadies on previously blank pages. The manuscript nowhere catalogues this organization; the layered anonymous repertory is the inferred object.
What is attested
- Evidence 1862 records: DIAMM records I-FZc MS 117 as a fifteenth-century parchment music source, with black mensural notations, Bonadies named as copyist, San Paolo Ferrara relationship, and 68 compositions including 42 anonymous items.
- Evidence 1863 records: DIAMM distinguishes an original layer of organ intabulations of fourteenth-century vocal works from a later group of fifteenth-century pieces and treatises added on previously blank pages by Johannes Bonadies.
- Evidence 1864 records: La Trobe's medieval music database describes Faenza 117 as an early complete instrumental-music manuscript with ornamented two-part arrangements and later Bonadies additions on specified folio ranges.
- Evidence 1865 records: Memelsdorff's abstract says new photography and digital restoration enabled restoration and transcription of previously illegible diminutions and newly recoverable pieces.
- Evidence 3956 records: Offline judge treated existing inferon 260 (source_dependence) as support for Codex Faenza anonymous repertory and layer inferon. Evidence strength: bounded but below-publication structural/source inferon; sufficient for L2 review, not for article promotion. The accountable path is EvidencePath 1433.
Why infer this entity
DIAMM's source record establishes the raw structure: a fifteenth-century parchment music manuscript with sixty-eight compositions of which forty-two are anonymous, and Bonadies named as a copyist (Evidence 1862). A second, independent DIAMM description distinguishes the original layer of organ intabulations from the later group of pieces and treatises added on blank pages (Evidence 1863), and the La Trobe database confirms the same layering with specified folio ranges (Evidence 1864). Joining these, the anonymous items fall into place as a coherent repertory with a stratigraphy - and Memelsdorff's restoration work shows that layer is still yielding legible, previously unreadable pieces, i.e. the repertory is larger than its currently edited surface (Evidence 1865). The counterevidence disciplines the claim's level: Sela and Granot warn against assuming compositional origin, sacred/secular status, or scribal unity (Evidence 1866), and Robinson's solo-organ argument unsettles the older functional categories (Evidence 1867). The inference is therefore held at the codicological level - that the layers and the anonymous repertory exist as organization - and not at the level of repertory classification, which remains open.
Evidence ledger
- Evidence 1862: DIAMM, I-FZc MS 117, DIAMM source record. DIAMM records I-FZc MS 117 as a fifteenth-century parchment music source, with black mensural notations, Bonadies named as copyist, San Paolo Ferrara relationship, and 68 compositions including 42 anonymous items. Role: Bibliographic control.
- Evidence 1863: DIAMM, I-FZc MS 117, DIAMM source record. DIAMM distinguishes an original layer of organ intabulations of fourteenth-century vocal works from a later group of fifteenth-century pieces and treatises added on previously blank pages by Johannes Bonadies. Role: Bibliographic control.
- Evidence 1864: La Trobe Medieval Music Database, Faenza, database record. La Trobe's medieval music database describes Faenza 117 as an early complete instrumental-music manuscript with ornamented two-part arrangements and later Bonadies additions on specified folio ranges. Role: Supporting evidence.
- Evidence 1865: Memelsdorff, New Music in the Codex Faenza 117, article abstract. Memelsdorff's abstract says new photography and digital restoration enabled restoration and transcription of previously illegible diminutions and newly recoverable pieces. Role: Supporting evidence.
- Evidence 1866: Sela and Granot, Faenza Codex figurations, publication abstract. Sela and Granot's abstract frames compositional origins, sacred/secular status, and one-or-many-scribe questions as assumptions to avoid in computational analysis. Role: Counterevidence.
- Evidence 1867: Robinson, The Faenza Codex: The Case for Solo Organ Revisited, article preview. Robinson's abstract challenges a simple secular/sacred repertory split and argues for solo-organ function, so older repertory categories should not be treated as settled. Role: Counterevidence.
- Evidence 3956: Offline existing-inferon judge ledger control source, existing_inferon_judge_promote:inferon:260. Offline judge treated existing inferon 260 (source_dependence) as support for Codex Faenza anonymous repertory and layer inferon. Evidence strength: bounded but below-publication structural/source inferon; sufficient for L2 review, not for article promotion. The accountable path is EvidencePath 1433. Role: Noetic interpretation.
Counterarguments
- Evidence 1866 weakens or qualifies the inference: Sela and Granot's abstract frames compositional origins, sacred/secular status, and one-or-many-scribe questions as assumptions to avoid in computational analysis.
- Evidence 1867 weakens or qualifies the inference: Robinson's abstract challenges a simple secular/sacred repertory split and argues for solo-organ function, so older repertory categories should not be treated as settled.
Confidence scores
- Direct attestation: 15
- Existence warrant: 78
- Specificity confidence: 58
- Reconstruction dependence: 70
- Counterevidence pressure: 0
What would change the score
- A direct attestation would move this out of the inferred catalogue.
- Stronger independent evidence would raise the warrant or specificity.
- Better counterevidence would lower the warrant or force retirement.
