Evidence & Sources (artbull-evidence-and-sources)

Beyond the object itself, an Art Bulletin argument rests on documentary and material evidence:

archives, inventories, contracts, letters, sale records, provenance chains, and technical/conservation

findings. This skill governs how you gather, weigh, and cite that evidence so an expert reviewer

trusts it. The looking lives in artbull-visual-analysis; here you handle everything else.

When to trigger

• Building the documentary basis for dating, attribution, patronage, or reception
• Reconstructing a provenance or ownership history
• Weighing conflicting documents or an uncertain attribution
• A reviewer questioned a source, a transcription, or a chain of provenance

Handling the evidence

1. Go to primary sources. Archival documents, inventories, contracts, wills, correspondence,

sale and exhibition records — cite the repository, collection, and shelf/inventory mark so

another scholar can find them.

1. Quote and translate carefully. Give original-language quotations where the wording matters,

with accurate translations; note editorial interventions in transcriptions.

1. Build provenance rigorously. Document the ownership chain with sources for each link; flag

gaps honestly, and surface any spoliation / restitution concerns rather than burying them.

1. Weigh attribution evidence. Combine documentary, visual, and technical grounds; state the

degree of certainty ("attributed to," "circle of," "documented as") and what would change it.

1. Use technical art history where it bears. X-radiography, infrared reflectography, pigment and

support analysis, dendrochronology — cite the report and who performed it; do not overstate what

science proves.

1. Distinguish evidence from inference. Separate what a document says from what you infer;

keep silent documents from being made to speak.

Anti-patterns

• Asserting a date or attribution with no documentary or technical basis
• Citing a source you have not seen (or a digital surrogate as if it were the original) without saying so
• Provenance with unexplained gaps presented as continuous
• Over-claiming what a scientific report establishes
• Burying a restitution / authenticity problem the evidence raises

Specialist referees for the College Art Association's quarterly weigh the kind and traceability of

evidence, not its volume.

| Evidence type | Trusted when… | Referee distrusts when… | Strengthening move |

|---|---|---|---|

| Archival document | Repository, collection, and shelf-mark cited; consulted in person | Cited from a secondary source as if seen | Verify the original, or name the surrogate used |

| Provenance link | Each owner change has its own source | A continuous chain papering over a gap | Flag the gap; never present a break as continuity |

| Technical report | Method, analyst, and date named; claims stay within the science | "Science proves" overreach (IRR, XRF, dendro) | State what the report can and cannot establish |

Worked vignette: reconstructing a contested provenance

Suppose an article dates a devotional diptych through its ownership history. A **1623 estate

inventory** in a named municipal archive (repository, fondo, and busta cited) records a "diptych with

the Virgin," the earliest secure link; the chain then jumps to an 1890s dealer ledger and a **1931

museum accession file**, leaving a gap c. 1650–1890 the draft must flag rather than smooth over. A

restitution concern surfaces — the 1931 accession passed through a dealer active in a region of

known wartime spoliation — so the article notes a looted-art database check rather than burying it.

Technical evidence stays in its lane: dendrochronology of the support yields a date *consistent

with* the dating, reported as corroboration, not proof. The certainty term lands at "documented

from 1623, with a provenance gap," naming the document that would close it.

Referee objections about sources, and the disciplinary fix

• "You cite a document you have not seen." Distinguish autopsy from secondhand citation; where you

relied on a transcription or digital surrogate, say so in the note.

• "A restitution / authenticity problem is buried." Foreground spoliation or forgery concerns the

evidence raises; candor about provenance ethics is a strength.

Calibration anchors (hedge where uncertain)

• The apparatus carrying this evidence lives in Chicago-style endnotes (CMOS notes; confirm the

current edition against the journal's current submission guidelines), documenting repositories,

shelf-marks, and transcriptions in full — with original-language quotation and translation where

wording bears weight for a global, multi-period readership.

Output format

【Claim supported】dating / attribution / patronage / reception
【Primary sources】repository + collection + shelf-mark
【Provenance】chain with sources; gaps flagged
【Technical evidence】report + analyst (if any)
【Certainty】documented / attributed / circle-of, and what would change it
