Printed Galen and Dio together record army mortality as a governance shock in the northern wars

Kühn’s Galen plus printed Dio record that the same epidemic emptied units Marcus needed on the Danube. In the causal graph this event weakens Health-System Capacity, a driver that strengthens Hospital beds (per 1,000 people) — a worsening welfare path.

Kühn’s Galen plus printed Dio record that the same epidemic emptied units Marcus needed on the Danube.

Context

Fighting a war in an epidemic is a health-and-force shock. It does not prove unique incompetence; it does prove a cost.

Marcus Aurelius is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.

Why it matters

Empty centuries are not a Stoic exercise.

Who was responsible

Contribution type and responsibility level for each recorded actor — not sole-author shorthand.

  • Marcus Aurelius

    Dated act under Marcus as emperor or as later printed subject. Scribes, heirs, editors, and museums share labour.

What the sources establish

Later competitions, monuments, translations, UNESCO listings, and museums are not converted into extra lifetime acts. That reading is an impact-path choice, not a property stored on the Fact itself. Confidence is stated on the impact path. A later English edition is not a recovered autograph. If a number is not in the two records named above, it is not supplied here.
