Inlaid Mahogany Sheraton Revival Mantel Clock

• 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.
• Thomas Sheraton - Thomas Sheraton (1751-1806) was born in Stockton on Tees in the north of England. He was apprenticed to a local cabinetmaker and after working as a cabinetmaker, Sheraton moved to London about 1790. Although he described himself as a cabinet-maker, like Chippendale, no definite piece of furniture can be traced to him as maker. Nevertheless, he was immensely influential and in 1791-4 published his four volume book 'The Cabinet-Maker and Upholsterer's Drawing Book'. The books were used as source of design by the furniture-making trade , who often simplified or modified the designs to suit their own preferences. Sheraton furniture is marked by restraint and sophistication, elegance and discretion, though he also found time to invent fanciful combination furniture.
• Mahogany - Mahogany is a dense, close grained red-coloured timber from the West Indies and Central America. It was first imported into Europe in the the early 18th century and its use continued through the 19th century. It was popular for furniture making because of its strength, the wide boards available, the distinctive grain on some boards, termed flame mahogany and the rich warm colour of the timber when it was polished.. The "flame" was produced where a limb grew out from the trunk of the tree, and this timber was usually sliced into veneers for feature panels on doors, backs and cornices.
  
  Some terms used to describe mahogany relate to the country from which it originally came, such as "Cuban" mahogany, "Honduras" mahogany etc. However unless the wood has been tested the names assigned are more a selling feature, rather than a true indication of the timber's origin.
• Edwardian - The Edwardian period of English furniture and decorative arts design is named for Edward VII (1841 ? 1910) who was King of the United Kingdom and the British Dominions and Emperor of India for the brief period from 1901 until his death in 1910. It follows the Victorian period, in turn was followed by the Art Nouveau and Art Deco styles. In Australia, designs of this period are also known as being in the Federation style.
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
