大アグリッピナ
At the time of Tiberius's death most of the people who might have succeeded him had been killed. The logical successor (and Tiberius' own choice) was his 24-year-old grandnephew, Gaius, better known as "Caligula" ("little boots"). Caligula was a son of Germanicus and Agrippina the Elder. His paternal grandparents were Nero Claudius Drusus and Antonia Minor, and his maternal grandparents were Marcus Vipsanius Agrippa and Julia the Elder. He was thus a descendant of both Augustus and Livia.
