Regency Clock with Griffin and Urn Decoration

• Ormolu - Ormolu was popular with French craftsmen in the 18th and 19th century for ornamental fittings for furniture, clocks and other decorative items. True ormolu is gilt bronze, that is bronze that has been coated with gold using a mercury amalgam. Due to the health risks associated with using mercury, this method of creating ormolu was discontinued in France in the 1830s. A substitute was developed consisting of about 75% copper and 25% zinc, however it was inferior to the bronze version. It was often lacquered to prevent it tarnishing.
• Regency Period - The Regency period in English furniture design refers to the period when King George III, was declared unfit to rule in 1811, and his son ruled as proxy as Prince Regent, until 1820, and then, after the death of his father as George IV until his death in 1830. The Regency period was preceded by the Georgian period (George I, George II, and George III: 1714 - 1811), and was followed by the William IV period, which only lasted until 1837 when William IV died as was succeeded by Queen Victoria.
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
• Anchor Escapement - An anchor escapement is a type of mechanical escapement used in clocks and watches. It is a refinement of the older verge escapement, which was used in early mechanical timekeeping devices. The anchor escapement is characterised by the use of an anchor-shaped pallet that rocks back and forth, alternately locking and releasing the escape wheel. This action allows the movement of the watch or clock to be regulated, producing the characteristic tick-tock sound that is associated with mechanical timekeeping devices. The anchor escapement is generally more accurate and reliable than the verge escapement, and it is still used in many modern clocks and watches today.
• Fusee - The fusee movement was used in clocks and pocket watches from the mid 17th century. The fusee is a cone shaped drum within the works that is linked to the barrel of the spring, usually by a length of chain.
  
  As the mainspring loses its tension over time, the cone shaped barrel compensates for this by increasing the tension, by pulling the mainspring tighter, thus ensuring the time remains constant.
  
  Use of the fusee in clocks was superseded by the "going barrel" in the mid 19th century and for pocket watches at the beginning of the 19th century.
  
  The fusee continued to be used in marine chronometers until the 1970s.
• Griffin / Griffon / Gryphon - A griffin, also known as a griffon or gryphon, is a mythical creature with the body of a lion and the head of an eagle. It is typically depicted as a powerful and majestic beast, with the body and legs of a lion and the head, wings, and talons of an eagle. The griffin is widely recognized as a symbol of strength, courage, and guardianship, and has been used in a variety of cultures throughout history.
  
  In ancient mythology, the griffin was often associated with the gods and was considered a symbol of divine power. In ancient Greece, for example, the griffin was associated with the sun god Helios, while in ancient Egypt, it was associated with the goddess Hathor. In medieval European heraldry, the griffin was used as a symbol of strength, valour, and protection, and was often featured on the coats of arms of noble families.
