Austro-Hungarian Empire Clock with Gilt & Alabaster

• 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.
• The Eagle - The eagle has been a symbol of power, victory, and strength for centuries. It is often associated with bravery, prowess, and dominance, and has been used as a symbol by many cultures and civilizations throughout history.
  
  In ancient Greece, the eagle was associated with the god Zeus, who was considered the king of the gods and the ruler of the skies. In many cultures, the eagle was seen as a messenger between the physical world and the spirit world, and was associated with the sun and the sky.
  
  In the Roman Empire, the eagle was the symbol of the Roman army, and was displayed on the standards of the soldiers to show the power and authority of the empire. In medieval Europe, the eagle was used as a symbol of power and victory by monarchs and rulers, and was often depicted in art and architecture as a symbol of strength and courage.
  
  In modern times, the eagle continues to be a symbol of power, victory, and strength. It is often used as a symbol by nations and organisations, and is frequently depicted in art and on monuments to commemorate important events and achievements.
  
  The eagle's powerful appearance, combined with its association with freedom, courage, and dominance, makes it a popular and enduring symbol of power and victory.
• Gesso - A mixture of plaster of Paris and gypsum mixed with water and then applied to the carved wooden frames of mirrors and picture frames as a base for applying gold leaf. After numerous coats of gesso have been applied, allowed to dry and then sanded a coat of "bole", a usually red coloured mixture of clay and glue is brushed on and allowed to dry, after which the gold leaf is applied. In painting, gesso is also used to prime a canvas prior to applying paint.
• Alabaster - Alabaster is soft natural stone used for statuary, with a similar appearance to marble, but easier to work with. As it is softer than marble, an item made from alabaster can be scratched with a metal object, and an alabaster item does not polish to a high surface gloss like marble.
  
  Alabaster objects can be semi-translucent. Alabaster occurs in a pure white form and also with veining from dirt. Colours vary from white through yellow and pink to brown. The veining is usually green or black but can be multicoloured.
  
  Being semi-translucent, alabaster is often used for the bowls of figural lamps, with the figure itself being either alabaster or marble.
