Perseus publishes a stable digital Suetonius Caligula for public reuse
By the mid-1990s Perseus at Tufts was serving Suetonius’s Caligula as public HTML. In the causal graph this event strengthens Digital Learning Access, a driver that weakens Learning Poverty Rate (low- and middle-income countries) — an improving welfare path.
Read the full account
By the mid-1990s Perseus at Tufts was serving Suetonius’s Caligula as public HTML. It is not a new manuscript.
Context
Digital classics let readers search ‘Incitatus’ without a rare Loeb. Editorial freeze remains.
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.
Who was responsible
Contribution type and responsibility level for each recorded actor — not sole-author shorthand.

Princeps as named in later editions and objects. Historians, museums, and later states publish the instrument.
