Sword swallowing is an ancient skill in which the performer passes a sword through the mouth and down the esophagus to the stomach. This feat is not swallowing in the traditional sense; the natural processes that constitute swallowing do not take place, but are repressed in order to keep the passage from the mouth to the stomach open for the sword.
The practice is dangerous and there is risk of injury.

Originating in south India before 2000 BC, swallowing has a long and varied history. During its early history it was used as a demonstration of divine union and power.
Sword swallowing spread to Greece and Rome in the 1st century AD and to China in the 8th century. In Japan, it became a part of the Japanese acrobatic theatre, Sangaku, which included fire eating, tightrope walking, juggling and early illusion. In Europe it developed into yet a third distinct type of performance associated with the medieval jongleurs, that of the street performance.
Sword swallowing was performed during the Middle Ages as part of street theatre and was popular at festivals and other large gatherings. It began to die out in the mid-19th century, and was outlawed in Scandinavia in 1893. This was due to a declining interest in street and festival theatre and a growing interest on the part of audiences in more "sophisticated" and "proper" theatre.
According to an early-19th century English magazine article  the abilities of sword-swallowers in India were considered incredible when first reported in England. In 1813 'swallowing the sword' was advertised as among the new and astonishing feats  performed by the Indian Jugglers then appearing in London. The troupe was led by the famous juggler and sword swallower Ramo Sammee, who continued to perform until his death in London in August 1850, having at times also toured Europe and America. From 1850 to the 1890s a small number of sword swallowers performed in the UK, such as Martha Mitchell (c 1855) and Benedetti (1863–95), and in the US, including Lawson Peck (c 1850s), Ling Look (c 1872), Wandana (died May 9, 1875), and Harry Parsons (died December 1880). The best-known North American sword swallower of this time was Fred McLone, better known to the public as "Chevalier Cliquot", who performed from 1878 to the early 20th century.
In 1893 sword swallowing was featured at the World Columbian Exposition at the Chicago World's Fair.
In the early 1900s traveling circuses and sideshows were the dominant venue for sword swallowers. It became competitive. In Europe performers tried to swallow large numbers of swords; in America there was a focus on the novel and bizarre.[clarification needed]
During the late 19th century and early 20th century traveling magic shows from the Orient toured Europe and America; some included sword swallowing
The middle of the 20th century saw a demise in circuses in general and sideshows in particular.
Anatomy and method
The performer must first lean the head back, hyper-extending the neck, and relax the upper esophageal sphincter (a generally involuntary muscle which contracts the top of the esophagus). Retching must be controlled while the sword, lubricated by saliva, is inserted through the mouth and past the pharynx.
Once past the pharynx and sphincter the sword passes swiftly, assisted by gravity, straightening the flexible esophagus. The stomach, at an angle to the esophagus, is brought into line as the sword enters through the cardiac opening. Some swallowers consume a large meal or drink water before performing to give the stomach a more vertical orientation, allowing for easier passage of the sword. Careful focus is required to complete the process without injury, as the sword passes within millimeters of vitals such as the aorta, heart and lungs.
Side effects and injuries
Most serious sword swallowing injuries and fatalities occur after minor injuries or while attempting a feat beyond that of a "normal" sword swallow. The most common injury is a sore throat when first learning, after frequent consecutive performances, or after swallowing curved swords or several swords at once. Swallowing multiple swords simultaneously over time can also lead to distension of the esophagus. A minor injury may predispose the performer to sustaining a more major one, including perforation of the esophagus, stomach, heart, lungs, and other organs in proximity to the path of the sword, or intestinal bleeding. Twenty-nine deaths have been reported as a result of sword swallowing injuries since 1880.
Medical case reports
- A 59-year-old man experienced chest pain and severe dysphagia following practice for his sword swallowing act. An esophageal perforation was found and surgically repaired; 19 days later a leak at the site required a transhiatal esophagectomy with a left cervical esophagogastrostomy. The patient recovered normally, but ceased the practice of sword swallowing.
- A 27-year-old woman reported neck pain and a single episode of hematemesis (vomiting blood) after pricking her throat while practicing her sword swallowing act with a sharp dagger. The injury was found to be immediately below the esophageal sphincter, and the patient was admitted to intensive care and placed on intravenous antibiotics and a proton-pump inhibitor. She recovered well and returned to all previous activities with the exception of sword swallowing.
Contributions to science
The abilities of sword-swallowers have proven useful to the progress of medical knowledge, specifically in the development and advancement of upper endoscopy.
In 1868 Adolf Kussmaul of Freiburg, Germany, performed an esophagoscopy on a sword-swallower using a rigid 47 cm tube, mirrors, and a gasoline lamp. The apparatus, an early endoscope, allowed him to examine the esophagus and the fundus of the stomach.
In 1897 a Scottish physician named Stevens performed digestive experiments with a sword swallower assistant; small metal tubes, pierced with holes and filled with meat, were swallowed and after a time regurgitated, allowing Stevens to examine the extent of the digestion that had taken place.
In 1906 a doctor named Cremer performed an electrocardiogram by passing an electrode down the esophagus of a sword swallower. This approach has since been proven useful by numerous studies; esophageal recording at a location in proximity to the heart improves signal detection.
From 2003 to 2006, a research study was conducted by Brian Witcombe, consultant radiologist at the Gloucestershire Royal Hospital in Gloucester, England, and Dan Meyer. The results were published in the British Medical Journal.
In January 2006, Dan Meyer worked with physicians and researchers in swallowing disorders at Vanderbilt Stallworth Rehabilitation Center at Vanderbilt University Medical Center in Nashville TN USA to explore whether the techniques involved in sword swallowing could be used to help patients who suffer from swallowing disorders such as dysphagia or achalasia or who had suffered from stroke or severe throat trauma and had difficulty in swallowing as a result.
In 2007, Dai Andrews worked with Dr. Sharon Caplan at Johns Hopkins University on a study to determine whether sword swallowing could be used to help patients who suffer from achalasia or those who had suffered severe throat trauma.
Guinness World Records
In 2009, the Guinness World Record for longest sword swallowed was achieved by Natasha Veruschka with a 58 cm (22.83 in) long sword.
Brad Byers holds the Guinness World Record for "The Most Swords Swallowed and Twisted at One Time" by swallowing ten 27 in swords one at a time and then twisting all 10 swords 180 degrees in his throat.
Thomas Blackthorne made the sword known as "The Sword of Swords". It holds the Guinness World Record for the most swallowed sword and has been swallowed by 40 of the world's most known sword swallowers.
