Self-Defence

The law requires no man to submit passively to the infliction of violence upon his person. He may always defend himself. If he is assaulted with blows, he may return blows; and if need be he may kill an assailant who attempts, or, rationally considered, seems to attempt to take his life. The principle, in all cases, is that the counter violence must be only so much as is necessary for defence. - The old rule of the law that any who was guilty of a felony deserved death, probably founded the rule that it is justifiable to kill any one who is attempting to commit a felony, such for example as murder, mayhem, or rape. This rule is generally included in the law of self-defence. A man may also justify any violence done in defence of his wife, child, or servant, and either of these persons may justify violence in behalf of husband, father, or master.

Semele

Semele, in Greek mythology, daughter of Cadmus, and sister of Ino, Agave, Autonoė, and Polydorus. She was beloved by Jupiter, and Juno, jealous and indignant, persuaded her to ask him that he would appear to her clothed in the attributes of his majesty. Having sworn to grant her every request she would make, and warned her in vain to desist from this, he unwillingly consented, appeared as the god of thunder, and she was consumed by the lightning; but the child with which she was pregnant was saved by Jupiter, who enclosed him in his own thigh until the period for his birth. This child was Dionysus (Bacchus).
