According to Suetonius, Caligula was quite proud of his "adiatrepsia" - shamelessness. He lived in habitual incest with all his sisters and was especially fond of Drusilla. He made her divorce her first husband and marry his friend and lover Marcus Aemilius Lepidus. In 37 he interrupted the wedding of Livia Orestilla so he could marry her himself - and then kicked her to the curb 24 hours later. Then he made Lollia Paulina divorce her husband and marry him - but he tired of her in six months. Then he married Caesonia, "a woman of reckless extravagance and wantonness". Six months into his rule, Caligula fell seriously ill. While he was sick in bed, Macro and Silanus apparently prepared for the worst. They started the wheels in motion for Gemellus to be declared the successor.
