Claim
13-year-old Andrew Benning was hanged for stealing... a spoon.
Correction

The boy’s name is recorded as Andrew Branning/Brenning, not “Benning,” and archival records show he was still alive after 1801, so the claim that he was hanged is incorrect.

Full reasoning

The linked TIME article itself names the boy Andrew Brenning, not “Benning.” More importantly, a record in The National Archives (UK) shows a petition concerning Andrew Branning in September 1802, describing him as a convict on board the hulks at Langston Harbour after his 1801 conviction for burglary of a silver spoon. If he was on a prison hulk in 1802, he was not hanged in 1801.

So there are two factual problems here:

  1. The name is wrong in the post (Benning vs. archival forms Branning / later retellings Brenning).
  2. The execution claim is wrong: archival evidence shows he survived the 1801 sentence and was still in custody in 1802.

This does not make the underlying point about the brutality of the law false — he was apparently sentenced to death for stealing a spoon — but the post overstates what happened to him.

Claim
In the time of King Athelstan, 12 pence would buy you a sturdy ox.
Correction

This overstates the buying power of 12 pence. In Æthelstan’s reign, an ox was valued at a mancus, and a mancus was worth 30 silver pennies.

Full reasoning

A scholarly discussion in the British Numismatic Journal notes that in an ordinance from Æthelstan’s reign, “an ox is valued variously at a mancus and at thirty pence.” Separately, Art Fund’s description of an Anglo-Saxon mancus explains that a mancus had a nominal value of 30 silver pennies.

So if an ox was priced at one mancus, and one mancus was 30 pence, then 12 pence would not buy an ox. The article’s sentence appears to understate the price of an ox by roughly a factor of 2.5.

Claim
Professor of Medicine at Oxford
Correction

William Petty was not Oxford’s professor of medicine. He studied medicine and held anatomy posts there, especially Tomlins Reader/Professor of Anatomy.

Full reasoning

The Oxford history page for the Department of Physiology, Anatomy and Genetics identifies William Petty as “Tomlins Reader of Anatomy” at Oxford. Standard biographical references likewise describe him as a physician and professor of anatomy at Oxford, not as Oxford’s professor of medicine.

So the post confuses Petty’s medical training and career as a physician with the specific academic office he actually held at Oxford, which was in anatomy, not medicine.
