context: Caligula was born in Antium (now Anzio) on August 31, 12. His father was the popular warlord Germanicus, the nephew and adopted son of the future Emperor Tiberius. Caligula's mother was Vipsania Agrippina, whose father was of low descent but advanced in ability and merit, Marcus Vipsanius Agrippa, a good friend and immediate assistant to Emperor Augustus. The Caligula family followed Germanicus in his pursuit. In military camps, Caligula was a kind of mascot for soldiers, dressed in a military outfit, along with small military boots. He got his nickname for these military boots (caligae): Caligula means "little military boot."
