Milonia Caesonia (- 41 CE) was a Roman empress and the fourth wife of Caligula. Little is written about her; though she is described as neither beautiful nor young; with a reckless extravagance and uncontrolled wantonness; and that she was loved devotedly and passionately by Caligula. Some stories claim that Caligula would often parade Caesonia in front of his troops; and sometimes would parade her naked in front of select friends. Caesonia and her daughter; Julia Drusilla; were murdered hours after Caligula's assassination.
