The affair continued into the next year. It was then that the affair between Messalina and Silius took a new turn. Silius, who had no children of his own, proposed to marry Messalina on condition that she allow him to adopt Britannicus. The plan was to overthrow Claudius and rule together as regents of Britannicus. She acquiesced and waited for Claudius to leave Rome before performing the sacrifice and entering the bigamous marriage. The illegal union was made known to Claudius by Callistus and Narcissus, freedmen in his service. Claudius had Messalina, Silius, and others who knew of the affair put to death. Messalina was given a knife to kill herself with, though a tribune of the Praetorian Guard had to force it through her neck. Images and statues of Silius and his associates were ordered to be destroyed.
