Lucius Caesar

The son of Marcus Vipsanius Agrippa and Julia the Elder, Augustus' only daughter, Lucius was adopted by his grandfather along with his older brother, Gaius Caesar.

As the emperor's adopted sons and joint-heirs to the Roman Empire, Lucius and Gaius had promising political and military careers.

However, Lucius died of a sudden illness on 20 August 2 AD, in Massilia, Gaul, while traveling to meet the Roman army in Hispania.

The untimely loss of both heirs compelled Augustus to redraw the line of succession by adopting Lucius' younger brother, Agrippa Postumus as well as his stepson, Tiberius on 26 June 4 AD.

Lucius' father Marcus Vipsanius Agrippa was an early supporter of Augustus (then "Octavius") during the Final War of the Roman Republic that ensued as a result of the assassination of Julius Caesar in 44 BC.

He was a key general in Augustus' armies, commanding troops in pivotal battles against Mark Antony and Sextus Pompeius.

Agrippa acted as tribune in the Senate to pass important legislation and, though he lacked some of the emperor's power and authority, he was approaching the position of co-regent.

The aurei and denarii issued in 13–12 BC made clear the Emperor's dynastic plans for Lucius and Gaius.

Their father was no longer available to assume the reins of power if the Emperor were to die, and Augustus had to make it clear who his intended heirs were in case anything should happen.

[20] The two heirs received many honours by citizens and city officials of the Empire, including Colonia Obsequens Iulia Pisana (Pisa), where it was decreed that proper rites must be observed by matrons to lament their passing.

[21] The caskets containing their ashes were stored in the Mausoleum of Augustus alongside those of their father Agrippa and other members of the imperial family.

The Maison Carrée ( French : "square house") was dedicated in Nemausus to Gaius and Lucius.
