Aqueduct start is infrastructure, not a personality.

Context

Water is a public good and a monument. Labour costs are not itemised here. Claudius’s completion is shared credit, hence complex contribution.

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.
