Marcia (mistress of Commodus)

Marcia Aurelia Ceionia Demetrias (died 193) was the alleged mistress (182–193) and one of the assassins of Roman Emperor Commodus.

[2] After Victor gave her a list she had asked for including all of the Christians sentenced to mines in Sardinia, she convinced Commodus to allow them to return to Rome.

The inscription found in Anagnia testifies that the city council decided to build a monument, commemorating her part in restoring the baths.

Commodus, upset by Marcia's reaction, then told his plan to Aemilius Laetus, the Praetorian prefect, and Eclectus, his servant.

The three conspirators were afraid he would vomit up all the poison, so they ordered Narcissus, a young athlete, to strangle Commodus for a large reward.
