French Marble Clock with Egyptian and Lion Motif

• Cassolette - The origins of the cassolette date back to medieval times, where they were commonly used to serve stews and other hot dishes at banquets and other formal occasions. In the 18th century, cassolette dishes began to be made from porcelain and were often decorated with ornate designs, making them popular as decorative pieces as well as functional serving dishes.
  
  During the 19th century, cassolette dishes became popular in French cuisine, where they were used to prepare and serve dishes such as cassolette de fruits de mer, a seafood stew, and cassolette de gibier, a game stew.
• 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.
