One conspirator against this man attempted to hide from him by falling off a horse and throwing up rabbit's blood, then placing a ram in a coffin and burning it in his place.

This emperor claimed the title "Germanicus Maximus" after signing a peace treaty and ending the Marcomannic Wars, which were waged by his predecessor.
