What did the Roman emperor Claudius write about the Etruscans?

The Roman emperor Claudius authored a 20-volume history of the Etruscans written in Greek. Unfortunately, all of his historical works have been lost, so the specific content and conclusions of his writing remain unknown.12

It is believed that Claudius may have had access to original or authentic Etruscan traditions through his first wife, Plautia Urgulanilla, who was of Etruscan descent. His interest in history was fostered early in his life by the historian Livy. Beyond his scholarly work, Claudius also demonstrated an interest in Etruscan culture during his reign by protecting the haruspices (Etruscan diviners) in Rome.123
