French Bronze Mantel Clock by Bailly, Late 19th Century

• Lion Mask - The lion mask has been used for centuries in various forms of art and design, including furniture, silver, and ceramics, and is usually y depicted as a stylized representation of the face of a lion, often with an open mouth and protruding tongue. and is often used as a handle, knob, or other decorative element.
  
  In furniture design, lion masks were popular in the neoclassical and Empire styles of the late 18th and early 19th centuries. They were often used as decorative elements on the legs or arms of chairs, as well as on cabinet and drawer pulls. It was also used as a handle, knob, or other decorative element.
  
  In silverware design, lion masks were often applied to tea and coffee pots, as well as on candlesticks, snuff boxes, and other small silver items. The lion mask was often used in combination with other neoclassical motifs, such as laurel wreaths or acanthus leaves, to create a sense of grandeur and classical elegance.
  
  In ceramics, lion masks were often depicted in relief, and were sometimes used in combination with other decorative elements, such as garlands or swags.
  
  

• Ormolu - Ormolu was popular with French craftsmen in the 18th and 19th century for ornamental fittings for furniture, clocks and other decorative items. True ormolu is gilt bronze, that is bronze that has been coated with gold using a mercury amalgam. Due to the health risks associated with using mercury, this method of creating ormolu was discontinued in France in the 1830s. A substitute was developed consisting of about 75% copper and 25% zinc, however it was inferior to the bronze version. It was often lacquered to prevent it tarnishing.
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
• Quatrefoil - A stylised four-circle design, itself contained within a larger circle, with Gothic origins and often seen as window designs in ecclesiastical architecture. The use of the motif was popular in Gothic Revival furniture of the 19th century.
• Foliate - Decorated with leaves or leaf-like forms.
• Back Plate - On many types of clocks, the movement operates between two plates, usually made of brass, one at the back, and the other at the front, which forms a mount for the dial.
  
  On English bracket, mantle and table clocks the backplate was often visible through a glass door or panel from the late 17th century, and could be profusely engraved with scrolling decorations, flowers, foliage, birds, and figures. The engraving could also include the maker?s name.
  
  The amount of engraving reduced and became simpler as the 18th century progressed, and by 1800, had been reduced to a border, often with the maker's name in the centre. By the early 1800s all decoration had ceased, and only the maker's name was added, and by the Victorian era, most bracket, mantle and table clocks had no engraving.
• 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.
• Bronze - An alloy of copper and tin, traditionally in the proportions of about 9 parts of copper to 1 part of tin.
  
  The discovery of bronze in Western Asia in the 4th century enabled people to create metal objects which were superior to those previoulsy possible because of its strength and hardness, and it has been used throughout the world for weapons, coins, tools, statuary and other decorative items.
  
  It is very fluid in a molten state, and its hardness, strength when set, and non-corrosive properties makes it most suitable for casting sculpture.
