Thor

Thor, in Scandinavian mythology, the first born of Odin and Frigga, the bravest and boldest of all the gods. He directed the winds and the seasons; agriculture and the family relations were under his special care; and, unlike Odin, he was opposed to war among men. In the Eddas he appears as the champion of gods and men, destroying monsters and giants with his bolts of thunder. A terrible hammer was hurled at his victim, and after the blow was dealt the weapon returned to his hand. His waist was bound with a girdle which forever renewed the strength he spent in battle. Thor has been compared with Hercules, Jupiter, and the old Saxon deity Irmin. The fifth day of the week has from him received its name, Thursday.

Threatening Letters

Threatening Letters, sent to persons for the purpose of extorting money, have been said to constitute a misdemeanor or criminal offence at common law. Blackstone says that threatening by letter (even without demand) to kill any of the king's subjects or to fire their houses, etc, was made high treason by a statute of Henry VIII.; and though this is no longer the law, the offence is punishable severely under existing statutes. In many of the United States there are statutory provisions, punishing with great severity an attempt to extort money by means of a threatening letter. It may be said generally that a threat, to be indictable, must be such as might naturally overcome a man of ordinary firmness and sagacity; and the money demanded under the threat must be money to which the sender of the letter has no right. In England, it would seem to be an offence at law to post up, on a placard or otherwise, a threatening notice.
