Marcus Aurelius Commodus Antoninus became the Roman emperor when his father died in 180 A.D. Commodus, in Anno Domini 183, was returning from the amphitheater, via a narrow and secret passage, to his palace. In the dark passageway, an assassin awaited; with drawn sword, he rushed at Commodus from the shadows and exclaimed, “The senate sends you this!” The death of the emperor was prevented by his guards, but thereafter Commodus was distrustful of and hostile to the Roman Senate. That is partly why the delators were brought back into use. 
In Roman society, the delator (from delatio, denunciation) supplemented the police. Rewards for the delators included “pecuniary rewards and public praise” and “citizenship for foreigners.” 
Because the work of these informers was rewarded, there was potential for abuse. One source describes how these delators got out of hand. During the time of Flavius Julius Valens Augustus, Eastern Roman Emperor from 364 to 378, there was widespread witchcraft in the empire. Emperor Valens began a witch hunt, to put a stop to the evil practice. “A certain Palladius was commissioned to see that the laws were enforced, and the informers [delators] by whom he was constantly surrounded are said to have bribed servants to secrete parchments upon which were written spells and other similar objects in the houses of wealthy merchants, so that when the official searchers came to examine the premises, these documents and amulets were soon discovered, and no mean blackmail could be safely levied.” 
Earlier, though, in the time of Emperor Commodus, witchcraft had flourished in Rome. Commodus himself was a devotee of the Cult of Mithras. Author Montague Summers tells how the “insane Commodus” ordered select handsome youths to be sacrificed at his altars. “Sacra Mithriaca homicidio vero polluit,” recorded one ancient author. The abominations of Commodus were done for the sake of extispicium, an examination of human entrails used to foresee the future. 
Around 192 A.D., portents unfavorable to Commodus were noticed. According to the Roman author Cassius Dio Cocceianus (Dion Cassius), “many eagles of ill omen soared about the Capitol and moreover uttered screams that boded nothing peaceful, and an owl hooted there.” Marcia, favorite concubine of Commodus, conspired with some in the emperor’s inner circle to do away with him. Marcia gave poison to Commodus, mixed in with his food. But due to the emperor’s immoderate drinking habits, he soon vomited out much of the poison. A wrestler named Narcissus was sent for and he strangled Commodus to death. 
Pertinax, successor to Commodus, condemned his predecessor’s memory. Surviving victims of Commodus “were recalled from exile, released from prison, and restored to the full possession of their honours and fortunes. The unburied bodies of murdered senators were deposited in the sepulchres of their ancestors; their memory was justified; and every consolation was bestowed on their ruined and afflicted families. Among these consolations, one of the most grateful was the punishment of the Delators; the common enemies of their master, of virtue, and of their country.” 
Which brings us to the return of the delators. These are the “anonymous sources” constantly being cited by newspapers such as The Washington Post and The New York Times. These delators accuse President Donald Trump of having made a pact (“colluded”) with “the devil” (Russia). Consulting the Malleus Maleficarum (Witches Hammer), it was decided the appointment of a Special Inquisitor was warranted. (Background: The Inquisition of Donald Trump, Ersjdamoo’s Blog, July 30, 2017.)
And so, tweeted the president on July 29, 2017, “Witch Hunt!” Fox & Friends had reported that the firm behind an infamous delation, the anti-Trump “golden showers” dossier, also worked for Russia. “In other words,” tweeted Trump, “Russia was against Trump in the 2016 Election…” (Emphasis added)
