Lucius Julius Caesar (17 BCE – 20 August, 2 CE), most commonly known as
Lucius Caesar, was the second son of
Marcus Vipsanius Agrippa and
Julia the Elder. He was born between 14 of June and 15 July 17 BCE with the name
Lucius Vipsanius Agrippa, but when he was adopted by his maternal grandfather Roman Emperor Caesar
Augustus, his name was changed to Lucius Julius Caesar. In the year of his birth, his maternal grandfather Caesar
Augustus adopted him and his brother
Gaius Caesar. He may have used the cognomen
Vipsanianus according to
adoption in ancient Rome or
Agrippa as his youngest brother
Agrippa Postumus after the
tria nomina Lucius Julius Caesar. He and his brother were raised and educated by their grandparents.
