Chinese Shang Dynasty Bronze Wine Vessel: Gu (1600-1046 B.C.)

• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
• Bronze - An alloy of copper and tin, traditionally in the proportions of about 9 parts of copper to 1 part of tin.
  
  The discovery of bronze in Western Asia in the 4th century enabled people to create metal objects which were superior to those previoulsy possible because of its strength and hardness, and it has been used throughout the world for weapons, coins, tools, statuary and other decorative items.
  
  It is very fluid in a molten state, and its hardness, strength when set, and non-corrosive properties makes it most suitable for casting sculpture.
• Important - Important is a word used in the antique trade to indicate an object should be ranked above other similar objects, and is therefore more valuable.
  
  The object could be considered important because it is by a famous designer or maker, has been shown at a major exhibition, is of exquisite workmanship, is rare or is a "one-off", was made for an important patron, and so on.
  
  Even further up the pecking order are objects that are described in catalogue descriptions as highly important or extraordinarily important.
