Loeb Suetonius and Dio print the forced deaths of Gemellus and Macro after the accession

The Loeb vita and Dio 59 record that Tiberius Gemellus, joint heir in Tiberius’s will, and the prefect Macro were removed by forced suicide or execution early in the reign. In the causal graph this event strengthens Judicial independence erosion (court capture), a driver that strengthens Rule of Law Gap from the Highest Governance Score — a worsening welfare path.

Read the full account

The Loeb vita and Dio 59 record that Tiberius Gemellus, joint heir in Tiberius’s will, and the prefect Macro were removed by forced suicide or execution early in the reign. The dated carriers are those editions. Palace killings without a public independent court are the judicial path.

Context

Accession violence is normal in the received Julio-Claudian story. That does not make it a trial. Confidence is medium because the sources are later and hostile, high that Gemellus did not reign.

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.

Why it matters

Heir-killing as printed is a judicial-independence erosion: the household is the court.
