OCTAVIA, the name of two princesses of the Augustan house.
A colony with Latin rights was founded on Pontiae in 313 B.C. Nero, Germanicus's eldest son, and the sisters of Caligula, were confined upon it; while Pandateria was the place of banishment of Julia, daughter of Augustus, of her daughter Agrippina the elder, and of Octavia, the divorced wife of Nero.
(I) Octavia, daughter of Gaius Octavius and sister of the emperor Augustus, was the wife of Gaius Marcellus, one of the bitterest enemies of Julius Caesar.
Though Octavia took out troops and money to him (35), he refused to see her and formally divorced her in 32, but she always protected his children, even those by Fulvia and Cleopatra.
By her first husband she was the mother of Marcus Marcellus (q.v.), who died in 23 B.C. (2) Octavia, daughter of the emperor Claudius, was the wife of Nero, by whom she was put to death.
