Colonial Kauri Long Case Clock with Cherub Mask Pediment

• Kauri - An evergreen conifer tree associated with New Zealand, but also grown in northern Australia, and islands around the Pacific rim including Borneo, Vanuatu and New Guinea. The timber is generally golden in colour, and straight grained without much knotting.
  
  A by-product of the kauri tree was the kauri gum, the fossilised resin extracted from the tree. The gum was obtained through digging, fossicking in treetops, or more drastically, by bleeding live trees. Kauri gum was used in the manufacture of varnishes and other resin-based products, and also crafted into jewellery, keepsakes, and small decorative items.
  
  Kauri forests were prolific in the north of the North Island of New Zealand. European settlers in the 1700 and 1800s realised that the timber from these tall trees with broad trunks would be ideal for ship building and construction and a thriving industry was established harvesting the kauri tree. The forests were substantially reduced, and now the remaining Kauri trees that grow in New Zealand are protected, and there are reserves in various areas of the North Island.
  
  The remaining stands of kauri in New Zealand are under threat from "kauri disease", a microscopic organism that causes dieback in the trees, with vast tracts either dead or dying.
• Art Nouveau Period - The Art Nouveau period was a cultural movement that emerged in the late 19th century, and was characterized by its emphasis on natural forms, flowing lines, and a decorative, ornamental style. Art Nouveau was a reaction against the ornate and heavily stylized designs of the previous era, and sought to create a new, more organic aesthetic.
  
  Art Nouveau was characterized by its use of sinuous, curving lines, as well as a focus on natural elements such as flowers, vines, and other organic shapes. Art Nouveau designers sought to create a total work of art, in which every element of a building or object was designed to be harmonious with the overall design.
  
  Some of the most iconic examples of Art Nouveau design include the Paris Metro entrances designed by Hector Guimard, the works of the artist Alphonse Mucha, and the architecture of Victor Horta in Brussels.
  
  The Art Nouveau period was at its peak between 1890 and 1910, but began to decline in popularity by the start of World War I. However, Art Nouveau remains an important influence on design and art to this day, and continues to be celebrated for its emphasis on natural forms and decorative style.
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
• 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.
