The Attestation Grading System

Infographic C-G02: The Codex Kythagoras Attestation Grading System (Grades A–D and Tiers T1–T4) with historical benchmark exemplars across the eight volumes of Imperium Romanum.

PURPOSE AND USAGE

Asset C-G02 is the universal attestation key and editorial badge for IMPERIUM ROMANUM: A Compendium of the Wars of Rome (390 BC–AD 476). Designed as a standardized video endcard and static reference plate, it establishes the four Attestation Grades (A–D), the four Source Tiers (T1–T4), the three foundational House Rules of the Codex Kythagoras methodology, and one concrete benchmark example drawn directly from the text for each grade.

1. HEADER CARTOUCHE

  • Top Super-title: "IMPERIUM ROMANUM : AN ATTESTATION-GRADED COMPENDIUM"
  • Main Title: "THE ATTESTATION GRADING SYSTEM"
  • Subtitle: "THE METHODOLOGICAL ENGINE OF THE CODEX KYTHAGORAS APPARATUS"

2. PANEL I (LEFT COLUMN, 60% WIDTH): THE ATTESTATION GRADES

  • AGrade A Block:

    • Badge: "GRADE A · CONTEMPORARY WITNESS / PHYSICAL CONFIRMATION"
    • Color Accent: Tyrian Crimson (#8B1A1A)
    • Definition: "Strict eyewitness observation, unmediated archival records, or physical epigraphic and archaeological horizons that test and verify the operational claim."
    • Benchmark Example: "The Capture of Decebalus (AD 106)"
    • Evidentiary Note: "Attestation Grade: A. Tier T1. Verified by the funerary stele of cavalry duplicarius Ti. Claudius Maximus at Grammeni (AE 1969/70.583) and corroborated by Scene 145 on Trajan's Column. Ground controls text."
Decapitation of the State: the Death of Decebalus
SlideNotebookLMDecapitation of the State: the Death of Decebalus from Optimus Princeps: Trajan's Dacian and Eastern Campaigns

  • BGrade B Block:

    • Badge: "GRADE B · CRITICAL HISTORICAL TRADITION / ANALYTICAL CONSENSUS"
    • Color Accent: Punic Ochre (#B5824A)
    • Definition: "Retrospective narrative compiled by rigorous historians possessing access to lost primary archives, participant memoirs, or official dispatches; operational geometry secure."
    • Benchmark Example: "The Cannae Double Encirclement (2 August 216 BC)"
    • Evidentiary Note: "Attestation Grade: B (Battle mechanics: A). Tier T1/T2. Polybius 3.107–118 drawing on Sosylus and Roman camp archives. The operational encirclement is historical fact; casualty figures remain the tradition's arithmetic."

  • CGrade C Block:

    • Badge: "GRADE C · EPITOME / DISTANT ANNALISTIC NARRATIVE / DRAMATIC EMBELLISHMENT"
    • Color Accent: Iron-Grey (#4A4E51)
    • Definition: "Accounts preserved only in late epitomes, rhetorical summaries, or patriotic annalistic reconstructions composed centuries after the event; underlying fact obscured by literary topoi."
    • Benchmark Example: "The Geese of Juno and the Capitoline Siege (390 BC)"
    • Evidentiary Note: "Attestation Grade: C. Tier T2/T3. Livy 5.47 and Plutarch Camillus. The seven-month siege and survival of the rock are historical (BGrade B); the cackling geese and heroic single combat of Manlius are dramatic tradition."

  • DGrade D Block:

    • Badge: "GRADE D · PIOUS FABRICATION / INVENTED VICTORY / TENDENTIOUS FORGERY"
    • Color Accent: Muted Slate (#70757A)
    • Definition: "Demonstrable post-facto inventions, patriotic reversals of actual disasters, rhetorical school exercises, or fraudulent documents designed to flatter dynastic or civic memory."
    • Benchmark Example: "The Camillan Redemption: 'Non Auro Sed Ferro' (390 BC)"
    • Evidentiary Note: "Attestation Grade: D. Tier T3/T4. Livy 5.49. The story of Camillus arriving at the scales, forbidding ransom, and destroying the Senones is an annalistic fable invented to deny that Rome purchased its survival with 1,000 pounds of gold."

3. PANEL II (RIGHT COLUMN, TOP HALF): THE FOUR SOURCE TIERS (T1–T4)

  • Tier T1: "T1 · PRIMARY DOCUMENTARY & ARCHAEOLOGICAL"
    • Criteria: Inscriptions, military diplomas, coins, papyri, excavated destruction strata, and autoptic participant dispatches (Res Gestae, Caesar, Ammianus, Claudius Maximus stele).
  • Tier T2: "T2 · CRITICAL HISTORIOGRAPHY ON LOST PRIMARY SUBSTRATES"
    • Criteria: First-rank analytical historians synthesizing lost contemporary archives and participant testimony (Polybius, Tacitus, Appian Civil Wars, Livy's surviving main decades).
  • Tier T3: "T3 · SECONDARY COMPENDIA, BIOGRAPHIES & FRAGMENTARY WITNESSES"
    • Criteria: Biographical, anecdotal, or regional writers working at a distance from primary archives (Plutarch, Suetonius, Diodorus, Cassius Dio via Xiphilinus, Velleius Paterculus, Herodian).
  • Tier T4: "T4 · EPITOMATORS, DECLAMATIONS & HISTORIA AUGUSTA INVENTIONS"
    • Criteria: Late-antique abridgments, moralizing digests, and pseudepigrapha (Florus, Eutropius, Orosius, late chronicles, and post-Caracalla Historia Augusta).

4. PANEL III (RIGHT COLUMN, BOTTOM HALF): THE THREE INVIOLABLE HOUSE RULES

  • Rule 1 (The Arithmetic Rule): "All ancient troop rosters, casualty claims, and booty valuations are designated 'the tradition's arithmetic' unless certified by AGrade A epigraphy or administrative papyri."
  • Rule 2 (The Legend Rule): "Patriotic tableaux, deathbed epigrams, and providential portents are cataloged as civic memory and theological reception, never as operational fact."
  • Rule 3 (The Spade Rule): "Where literary narratives conflict with excavated destruction horizons, coin-hoard seal dates, or dendrochronology, the physical ground sits as judge upon the stylus."

5. FOOTER REGISTER

  • Left Text: "CODEX KYTHAGORAS · METHODOLOGICAL ENGINE"
  • Center Motto: "ADVENTUM AD ACTA · VERITAS SINE METU"
  • Right Text: "IMPERIUM ROMANUM : VOLS. I–VIII (390 BC – AD 476)"

A pristine technical infographic reference card on an aged cream background (#F4EBD5), framed by an elegant terracotta border (#A85638) with delicate gold corner rosettes (#B89954). At the top, a formal Roman gold cartouche features crisp, dark-sepia serif lettering reading 'IMPERIUM ROMANUM' and 'THE ATTESTATION GRADING SYSTEM'. Below, the layout divides into two balanced columns with crisp hairline dividers. The left column presents four distinct horizontal badge blocks for the Attestation Grades: a Tyrian crimson badge labeled 'GRADE A · CONTEMPORARY WITNESS / PHYSICAL CONFIRMATION' with small serif text describing autopsy and citing 'Capture of Decebalus (AD 106)'; a Punic ochre badge labeled 'GRADE B · CRITICAL HISTORICAL TRADITION' citing 'Cannae Encirclement (216 BC)'; an iron-grey badge labeled 'GRADE C · EPITOME / DRAMATIC TRADITION' citing 'Geese of Juno (390 BC)'; and a slate-grey badge labeled 'GRADE D · PIOUS FABRICATION' citing 'Camillus: Non Auro Sed Ferro'. The right column contains two stacked sub-panels: the upper sub-panel outlines 'SOURCE TIERS' from 'T1 · PRIMARY DOCUMENTARY' to 'T4 · EPITOMATORS & FABRICATIONS' in clean tabular lines; the lower sub-panel displays 'THREE HOUSE RULES' numbered 1 through 3 in clear italicized serif. The entire composition has the precision of an antiquarian staff-college plate, featuring clean typography, perfect alignment, exact color codes, no stray symbols, and no pictorial figures.
