any writer who produced a type of character sketch that was popular in 17th-century England and France. Their writings stemmed from a series of character sketches that the Greek philosopher and teacher Theophrastus (fl. c. 372 BC) had written, possibly as part of a larger work and probably with the intention of instructing and amusing his students of rhetoric. Theophrastus' technique was to define an undesirable personal quality (such as vanity or stinginess) and then to describe the characteristic speech and behaviour of a man who exemplified it. His work was introduced to Europe during the Renaissance in an edition of 1529; admiring his wit and insight into human failings, a number of contemporary writers imitated his example. They included, in France, Jean de la Bruyère, and, in England, Joseph Hall, Sir Thomas Overbury, John Earle, and Samuel Butler.
