Epistemic status

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

Inferon for Diophanes of Nicaea/Bithynia as the agronomic source node mediating the Mago and Cassius Dionysius tradition through a lost six-book epitome.

What is being inferred

At issue as the inferred object is a source chain, not a lost book: the claim is that Diophanes of Bithynia occupies a specific link in the transmission of Carthaginian and Greek agricultural writing into Latin agronomy, abridging earlier material for a named patron, and that this link is recoverable from later Latin citation even though no text by Diophanes himself survives.

What is attested

  • Evidence 2129 records: Varro lists Diophanes of Nicaea among Greek agricultural writers and says Diophanes in Bithynia abridged Cassius Dionysius into six books for Deiotarus.
  • Evidence 2130 records: Columella names Diophanes Bithynius and says he compressed Dionysius of Utica/Mago material into six epitomes.
  • Evidence 2131 records: The overview places Diophanes of Nicaea in Bithynia in the Mago/Cassius agricultural transmission chain, used only as orientation.
  • Evidence 3922 records: Offline judge treated existing inferon 277 (source_dependence) as support for Diophanes of Bithynia agronomic source-chain inferon. Evidence strength: bounded but below-publication structural/source inferon; sufficient for L2 review, not for article promotion. The accountable path is EvidencePath 1493.

Why infer this entity

Two independent Latin agronomists name Diophanes and describe the same abridging role: Varro (Evidence 2129) lists Diophanes of Nicaea among Greek agricultural writers and states that Diophanes in Bithynia abridged Cassius Dionysius into six books for Deiotarus, and Columella (Evidence 2130), writing separately, names Diophanes Bithynius and says he compressed Dionysius of Utica/Mago material into six epitomes. Because Varro and Columella are different authors writing at different times rather than one copying the other, their agreement on the six-book abridgment is the load-bearing warrant for placing Diophanes at this specific point in the chain. The Wikipedia overview on the Geoponici (Evidence 2131) is used only as orientation, situating Diophanes within the wider Mago/Cassius transmission stream, not as an independent premise. The packet contains no counterevidence item; nothing here disputes the abridgment claim, and that absence is recorded rather than treated as reinforcing the source chain.

Evidence ledger

  • Evidence 2129: Varro, On Agriculture 1.1, On Agriculture 1.1. Varro lists Diophanes of Nicaea among Greek agricultural writers and says Diophanes in Bithynia abridged Cassius Dionysius into six books for Deiotarus. Role: Primary trace.
  • Evidence 2130: Columella, De Re Rustica 1, De Re Rustica 1. Columella names Diophanes Bithynius and says he compressed Dionysius of Utica/Mago material into six epitomes. Role: Primary trace.
  • Evidence 2131: Wikipedia, Geoponici, overview. The overview places Diophanes of Nicaea in Bithynia in the Mago/Cassius agricultural transmission chain, used only as orientation. Role: Lead context.
  • Evidence 3922: Offline existing-inferon judge ledger control source, existing_inferon_judge_promote:inferon:277. Offline judge treated existing inferon 277 (source_dependence) as support for Diophanes of Bithynia agronomic source-chain inferon. Evidence strength: bounded but below-publication structural/source inferon; sufficient for L2 review, not for article promotion. The accountable path is EvidencePath 1493. Role: Noetic interpretation.

Counterarguments

  • The packet contains no separate counterevidence item; this absence does not remove the need for challenge.

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.
