Res Gestae Divi Augusti

Succession

Augustus was succeeded by his adopted stepson Tiberius (14–37 CE), founding the Julio-Claudian dynasty. Subsequent emperors — Caligula, Claudius, and Nero — were all descendants or adoptees within this line. ³

After his death, Augustus was deified by the Senate and proclaimed a god in the Roman pantheon. ²

Archaeology

University of Tokyo excavations at Somma Vesuviana (ongoing since 2002) have uncovered a sprawling ~40,000-square-foot villa buried by the 79 CE eruption of Mount Vesuvius. Researchers believe this may be the lost villa where Augustus died in 14 CE, as ancient sources describe him dying in a villa north of the mountain, in an area where his noble family is known to have had an estate. The site includes evidence of a private bathhouse and storage amphorae consistent with an elite residence. @t[~14] ⁶

In July 2025, the team unearthed five large furnaces used to heat an enormous bath complex — an unprecedented find at any Italian site. Lead archaeologist Mariko Muramatsu concluded that the scale of the structure points to imperial ownership: "There has never been a case where five large furnaces have been excavated from an Italian site. It makes sense as an explanation that no one else but the emperor could make such a magnificent feat possible." No indisputable direct epigraphic evidence linking the villa to Augustus has yet been found; excavations are ongoing. ⁷
