# Loeb Suetonius prints poison, illness, and ‘madness after a disease’ as a medical legend

Date: 1913

## The fact

Rolfe prints the received story that a serious illness turned Gaius from a generous heir into a monster, plus poison anecdotes. This is not a diagnosis. Storing it as a public medical legend warns against using disease as a moral solvent.

## Context

Illness as alibi can block institutional constraints: if the princeps is ‘mad’, law is pointless. Low confidence on any pathogen. High that later readers wanted a medical plot.

[Caligula](/people/caligula) 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.

## Evidence and sources

Official edition, museum, or agency page and an independent publisher independently describe this instrument.

Official or archival record: Suetonius, Caligula — LacusCurtius (Loeb English) (https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Suetonius/12Caesars/Caligula*.html; LacusCurtius / University of Chicago).

## Significance

A printed madness-after-fever legend is a low-confidence medical-alibi path, not a chart.

## What is established and what is not

Established as a dated public record of this instrument.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.
