Reference excerpt

The Scavenger's daughter, also known as the Skevington's gyves, iron shackle, stork, or Spanish A-frame was a type of torture device invented in England during the reign of King Henry VIII.

History

The Scavenger's Daughter (or Skevington's Daughter) was invented as an instrument of torture in the reign of Henry VIII by Sir Leonard Skevington, Lieutenant of the Tower of London, a son of Sir William Skeffington (died 1535), Lord Deputy of Ireland, and of his first wife, Margaret Digby. The device consisted of a metal rack shaped into an A-frame; the victim's head was strapped to the top point of the A, the hands at the midpoint, and the legs at the lower spread ends. The frame could fold, swinging the head down and forcing the knees up into a sitting position, compressing the body so as to force blood from the nose and ears. The Scavenger's Daughter was conceived as the perfect complement to the Duke of Exeter's daughter (the rack) because it worked according to the opposite principle - by compressing the body rather than stretching it. The best-documented use is that on the Irishman Thomas Miagh, charged with being in contact with rebels in Ireland. It may be in connection with the Scavenger's Daughter that Miagh carved on the wall of the Beauchamp Tower in the Tower of London, "By torture straynge my truth was tried, yet of my libertie denied. 1581. Thomas Miagh." Another victim of the Scavenger's Daughter was Thomas Cottam, an English Catholic priest and martyr from Lancashire, who suffered it twice in the 1580s before being released. Cottam was executed in 1582 during the reign (1558-1603) of Henry's daughter, Elizabeth I. Likewise, on 10 December 1580, the priest Luke Kirby was subjected to it.

The Scavenger's Daughter is also known as Skevington's gyves, as iron shackle, as the Stork (as in Italian cicogna) or as the Spanish A-frame. Further it is known as Skevington's daughter, from which the more commonly known folk etymology using "Scavenger" is derived. There is a Scavenger's daughter on display in the Tower of London museum.

Worked examples

Example 1 — a first encounter with Skevington's gyves

Start with the simplest possible case. Write down what Skevington's gyves claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Skevington's gyves before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Skevington's gyves ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Skevington's gyves

In research: Skevington's gyves appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Skevington's gyves in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Skevington's gyves is common in secondary-school and first-year university syllabi. It links to neighbouring topics English inventions, European instruments of torture, Modern instruments of torture, so understanding it makes those chapters shorter.
In everyday life: Look for Skevington's gyves outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
