Sharper

A sharper is an older term, common since the seventeenth-century, for thieves who use trickery to part an owner with his or her money or other possessions.

Sharpers vary from what are now known as con-men by virtue of the simplicity of their cons, which often were impromptu, rather than carefully orchestrated, though those certainly happened as well.

The 1737 Dictionary of Thieving Slang defines a sharper as "A Cheat, One who lives by his wits".

The appeal of an independent society, operating outside the law, has been imaginatively evocative for centuries, but in eighteenth-century London philosophical thought, influenced by Thomas Hobbes and Rousseau's new formulations of social contract, the romanticization of thievery reached new levels.

John Gay's The Beggar's Opera and Henry Fielding's novel Jonathan Wild are only two examples of sharpers as heroes, in these cases, to provide satirical ammunition against Robert Walpole, the British Prime Minister.
