this statue
Note from 'Justin, Justinian, and Theodora' chapter from 'The Secret History by Procopius

This extraordinary story, already current before Procopius's time, seems to have been invented to account for the strange appearance of the statue. It was probably not Domitian's corpse but his statue that had been pieced together, it having been smashed like the others by order of the Senate. As for the devoted widow, Domitia, there is little doubt that she had a hand in her husband's murder.
