Cocceius Auctus
Lucius Cocceius Auctus was a Roman architect employed by Octavian's strategist Agrippa to excavate the subterranean passageways known as the crypta neapolitana connecting modern-day Naples and Pozzuoli and the Grotta di Cocceio, connecting Lake Avernus and Cumae. Cocceius was responsible for the conversion of the Capitolium in Pozzuoli into a Temple of Augustus with the backing of the merchant Lucius Calpurnius. Cocceius Auctus also built the original Pantheon in Rome.
