Vienna Regulator Wall Clock in Neoclassical Cabinet

• 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.
• Anthemion -
  An anthemion is a classical decorative design element based on the acanthus flower that consists of a central circular or oval motif surrounded by radiating petals or leaves. It is often used as a border or frieze in architecture, furniture, and other decorative arts. The anthemion is derived from the palmette, a motif that was popular in ancient Greek and Roman art and architecture. It is often associated with the classical world and with Neoclassical style, and it is often used to add a sense of grandeur and formality to a design. The anthemion is also known as a honeysuckle or honeysuckle ornament. It continues to be used in a variety of contexts today, and it is often admired for its elegant and decorative qualities.
