Parricide
one who murders his father, ancestors, or any one to whom reverence is due. The Athenians had no law against parricides, from an opinion that human atrocity could never reach to the guilt of parricide. This was also originally the case at Rome; but at a later period the delinquent, after being scourged, was placed in a leathern sack, with a dog, a cock, a viper, and an ape, and so cast into the Tiber. The English and American law treat this crime as simple murder.
