Have you heard the saying, "The rule of thumb?"
There actually used to be a rule you could bring your wife to the local court house and beat her with a stick as long as it wasn't larger round than your thumb.
"Early References
A reference to this connection is found in 1881, in a book by Harriet H. Robinson:
Massachusetts in the Woman Suffrage Movement. She says there, "By the English common law, her husband was her lord and master. He had the custody of her person, and of her minor children. He could 'punish her with a stick no bigger than his thumb,' and she could not complain against him."
Most of her statement is undoubtedly true: married women had little recourse if a husband treated her or her children badly, including many acts of battery.
There was an 1868 case,
State v. Rhodes, where a husband was found innocent because, the judge said, "the defendant had a right to whip his wife with a switch no larger than his thumb," and in another case in 1874,
State v. Oliver, the judge cited the "old doctrine, that a husband had a right to whip his wife, provided he used a switch no longer than his thumb" but continued on that this was "not law in North Carolina.
Indeed, the Courts have advanced from that barbarism...."
A 1782 cartoon by James Gillray depicted a judge, Francis Buller, supporting this idea — and earned the judge the nickname, Judge Rule."
