Legend starts at about 5 on the clock and reads counter-clockwise: Caesar Augustus son of god [the deified Julius] father of the nation

In 2 BCE the Senate and people conferred on Augustus the title Pater Patriae, father of the nation, the last in a long list of honorific titles. It did not increase his powers, but honored him as father of the state; moreover, the title would surely recall the patria potestas, the power that a father exercised over the family.

Gaius and Lucius were Augustus' grandsons by Agrippa, whom Augustus adopted and hoped would succeed him.

• In 5 BCE, Gaius was named consul designate for five years thence (=1 CE) and Lucius for 4 CE; both were styled 'princes of the youth' and were given a shield and spear.
• Gaius was appointed a pontifex, represented by the simpulum (ladle) near him on your left, and Lucius an augur, represented by the lituus (augur's staff) near him on your right.
• Lucius died in 2 CE and Gaius in 4 CE
