Scarlet Chinoiserie Long Case Clock by William Monk (1740)

• Pendulum - The pendulum was discovered around 1602 by Galileo Galilei, and was adopted for time keeping by the Dutch mathematician and natural philosopher, Christiaan Huygens, who excelled in astronomy, physics, and horology.
  
  The pendulum comprises a metal rod usually of brass or steel with a metal disk, known as a bob, at the end. The movement of the pendulum is driven by weights or a spring, and as a pendulum swings in a regular arc, it was found accuracy could be controlled to within a few seconds a week.
  
  Timekeeping can be adjusted by changing the height of the bob on the rod, making the pendulum either swing slower or faster.
  
  The disadvantage of the pendulum was that changes in temperature also changed the length of the pendulum, interfering with the accuracy of the clock, and so in the 18th century two types of mercurial pendulums were invented which countered the movement in the steel rod.
  
  The pendulum was the world's most accurate timekeeping technology until the invention of the quartz clock, regulated by a quartz crystal, in 1927.
• Boss - A boss is small round or oval decorative device, used as ornament in Neo-classical style furniture, ceramics, sculpture and other decorative arts. They are usually applied to the surface in the form of stylized rosettes, but in the best pieces they are carved directly into the surface. Also known as paterae (or patera) or rosettes.
• Spandrel - An architectural term that in horology refers to the triangular ornamental decoration in the corners of of the dial plate. The spandrels are usually of cast brass and may be additonally chased and engraved. On painted dial clocks the spandrels are also usually painted.
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
• Chinoiserie - Furniture and decorative items decorated in imitation of a Western interpretation of the Chinese style. The Chinoiserie style first became popular in the late 17th century, though there were frequent revivals, notably by Chippendale (hence 'Chinese Chippendale') during the Regency period, and the Anglo-Japanese style in the second half of the 19th century.
  
  The ubiquitous 'willow pattern' is the most common 'Chinese' theme used in porcelain, while on furniture the Chinoiserie style usually has black or red painted and lacquered decoration, though the hallmark of the furniture style is the use of fretwork in geometrical patterns, pagodas and other decorative forms.
  
  Japonaiseries, as the name implies, are motifs in imitation of the Japanese taste.
  
  See also "Chinese Chippendale".
• Grotesque - Grotesque decoration is any fanciful ornament applied to furniture and decorative arts, and includes distorted faces, mythical animals such as satyrs and sphinxes and less frequently fantastical fruit and flower forms.
  
  The Martin Brothers who set up their pottery at the end of the nineteenth century in Southall, Middlesex derived their fame from their hand made models of grotesque stoneware birds.
• Hood - In longcase clocks, the hood is the wooden case that surrounds the works and dial, and includes the glass front, which is usually hinged, so the door can be opened to wind the clock or adjust the time. In 18th and 19th century longcase clocks the hood usually slides forward for removal, allowing access to the works.
• Chapter Ring - A separate metal plate on the face of a clock, on which the numerals for the hours and sometimes parts of the hours, are displayed, usually wheel shaped and sitting on top of the dial plate. The chapter ring is often a feature of the clock and can be silvered or enamelled to stand as a contrast to its background. The hours are usually shown in Roman numerals, although in the late 19th and earlt 20th century, Arabic numerals became fashionable.
• George Ii - George II (1683 - 1760) was King of Great Britain and Ireland from 1727 until his death in 1760.
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
