Neoclassical Empire Portico 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.
• Floral Swag / Garland / Festoon - Floral swags are a decorative motif often used in the ornamentation of various objects, such as silverware, glassware, and furniture. The term "swag" refers to a garland or wreath of flowers, foliage, or other decorative elements, which is usually arranged in a loop or curve.
  
  Floral swags can be found in a variety of decorative styles, from ornate Baroque and Rococo designs to more naturalistic Art Nouveau and Art Deco styles. They are often used to add a touch of elegance, refinement, or whimsy to an object, and can be seen on a range of items from chandeliers and candlesticks to picture frames and tea sets.
  
  In the decoration of silver objects, floral swags are often used to accentuate the curves and lines of the piece, and to add visual interest to the surface. Similarly, on glass objects, floral swags may be used to frame or highlight a particular area of the object, or to add a touch of color and delicacy.
  
  On furniture, floral swags can be found on a variety of pieces, from cabinets and armoires to chairs and sofas. They are often used to enhance the lines and curves of the furniture, and can be used to create a sense of movement and flow in the design.
  
  Overall, floral swags are a versatile decorative element that can be adapted to a range of styles and applications, and have been used in the decoration of various objects throughout history.
• Engine Turned - Engine turning is a decorative technique used on metal surfaces to create intricate curving or geometric pattern. The process involves cutting a series of lines into the surface of the metal using a rose engine or decoration lathe which rotates the metal as it cuts, allowing the operator to create a repeating pattern that covers the entire surface. The resulting surface has a shimmering, reflective quality that is often described as "engine turned." Where an engine turned item has been enamelled, the term used to describe the decoration is usually guilloche.
  
  Engine turning was originally developed to decorate metal objects such as firearms, scientific instruments, and other metal objects that required precise and elegant design.
• 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.
