[4] A relation to the Lentuli would help to explain why Orestilla was chosen to become the mother of Julian heirs.

[5] She was originally married to Gaius Calpurnius Piso, who was later involved in a conspiracy to overthrow Nero in AD 65.

Suetonius claims that Caligula issued a proclamation the next day that he had acquired a new wife in the tradition of Romulus and Augustus, who had both stolen wives from other men.

Orestilla was apparently an unwilling Empress, and remained loyal to her first husband.

[7] On the next day Caligula divorced Orestilla; however, he also prohibited her from returning to her relationship with Piso.
