A constable is a person holding a particular office, most commonly in law enforcement. The office of constable can vary significantly in different jurisdictions.

Historically, the title comes from the Latin comes stabuli (count of the stables) and originated from the Eastern Roman Empire; originally, the constable was the officer responsible for keeping the horses of a lord or monarch. The title was imported to the monarchies of medieval Europe, and in many countries developed into a high military rank and great officer of State (e.g., the Constable of France).

Most constables in modern jurisdictions are law enforcement officers; in the United Kingdom, Commonwealth of Nations and some European countries, a constable is the lowest rank of police officer (it is also, when preceded by the term 'sworn', used to describe any police officer with arrest and other powers), while in the United States a constable is generally an elected peace officer with lesser jurisdiction than a sheriff. However, in the Channel Islands a constable is an elected office-holder at the parish level.

Thomas Patrick Keating (March 1, 1917 - February 12, 1984) was an art restorer and famous art faker who claimed to have faked more than 2,000 paintings by over 100 different artists.

Keating was born in Lewisham, London, into a poor family. After World War II he began to restore paintings for a living, though he also worked as a house painter to make ends meet. He exhibited his own paintings, but he failed to break into the art market. He had a wife Hellen that he separated from in his later years. They had a son called Douglas.

Keating perceived the gallery system to be rotten, dominated, he said, by American "avant-garde fashion, with critics and dealers often conniving to line their own pockets at the expense both of naive collectors and impoverished artists". Keating retaliated by creating forgeries to fool the experts, hoping to destabilize the system.

John Constable (11 June 1776 – 31 March 1837) was an English Romantic painter. Born in Suffolk, he is known principally for his landscape paintings of Dedham Vale, the area surrounding his home—now known as "Constable Country"—which he invested with an intensity of affection. "I should paint my own places best", he wrote to his friend John Fisher in 1821, "painting is but another word for feeling".

His most famous paintings include Dedham Vale of 1802 and The Hay Wain of 1821. Although his paintings are now among the most popular and valuable in British art, he was never financially successful and did not become a member of the establishment until he was elected to the Royal Academy at the age of 52. He sold more paintings in France than in his native England.

John Constable was born in East Bergholt, a village on the River Stour in Suffolk, to Golding and Ann (Watts) Constable. His father was a wealthy corn merchant, owner of Flatford Mill in East Bergholt and, later, Dedham Mill in Essex. Golding Constable also owned his own small ship, The Telegraph, which he moored at Mistley on the Stour estuary and used to transport corn to London. He was a cousin of the London tea merchant, Abram Newman. Although Constable was his parents' second son, his older brother was mentally handicapped and so John was expected to succeed his father in the business, and after a brief period at a boarding school in Lavenham, he was enrolled in a day school in Dedham. Constable worked in the corn business after leaving school, but his younger brother Abram eventually took over the running of the mills.

Eric Patrick Clapton, CBE, (born 30 March 1945) is an English guitarist and singer-songwriter. Clapton is the only three-time inductee to the Rock and Roll Hall of Fame: once as a solo artist, and separately as a member of The Yardbirds and Cream. Clapton has been referred to as one of the most important and influential guitarists of all time. Clapton ranked second in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time" and fourth in Gibson's Top 50 Guitarists of All Time.

In the mid 1960s, Clapton departed from the Yardbirds to play blues with John Mayall & the Bluesbreakers. In his one-year stay with Mayall, Clapton gained the nickname "Slowhand". Immediately after leaving Mayall, Clapton formed Cream, a power trio with drummer Ginger Baker and bassist Jack Bruce in which Clapton played sustained blues improvisations and "arty, blues-based psychedelic pop." For most of the 1970s, Clapton's output bore the influence of the mellow style of J.J. Cale and the reggae of Bob Marley. His version of Marley's "I Shot the Sheriff" helped reggae reach a mass market. Two of his most popular recordings were "Layla", recorded by Derek and the Dominos, another band he formed and Robert Johnson's "Crossroads", recorded by Cream. A recipient of seventeen Grammy Awards, in 2004 Clapton was awarded a CBE for services to music. In 1998, Clapton, a recovering alcoholic and drug addict, founded the Crossroads Centre on Antigua, a medical facility for recovering substance abusers.
