French Oak Louis XIII Desk, 1880s

• Oak - Native to Europe and England, oak has been used for joinery, furniture and building since the beginning of the medieval civilisation. It is a pale yellow in colour when freshly cut and darkens with age to a mid brown colour.
  
  Oak as a furniture timber was superceded by walnut in the 17th century, and in the 18th century by mahogany,
  
  Semi-fossilised bog oak is black in colour, and is found in peat bogs where the trees have fallen and been preserved from decay by the bog. It is used for jewellery and small carved trinkets.
  
  Pollard oak is taken from an oak that has been regularly pollarded, that is the upper branches have been removed at the top of the trunk, result that new branches would appear, and over time the top would become ball-like. . When harvested and sawn, the timber displays a continuous surface of knotty circles. The timber was scarce and expensive and was used in more expensive pieces of furniture in the Regency and Victorian periods.
• Foliate - Decorated with leaves or leaf-like forms.
• Rosette - A stylised circular-shaped disk with turned or carved decoration decoration applied to a surface, or carved into the surface, especially used in ceramics, jewellery, furniture, sculpture and textiles. Also known as a boss or a paterae or patera.
• Barley Twist - The leg, and frequently other uprights such as columns, chair frames, spindles and stretchers, are turned in fairly wide and deep spirals, usually slightly rounded. Also known as the 'Jacobean twist' and common on the dark stained Jacobean Revival furniture of the 1930s and 40s.
  
  As a rule, the twists on opposite uprights should move in a contrary direction. Thus, if the spiral on a right side is clockwise, that on the left side should move in a counter-clockwise direction.
  
  This is also true of rope-twist or cable-twist turning, a nautical term that came into fashion after Nelson's victories over the French fleet. The essential difference is that with rope twists, the spirals are more finely turned on the lathe and placed closer together, than they are with barley-sugar turnings.
• 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.
• Turning - Any part of a piece of furniture that has been turned and shaped with chisels on a lathe. Turned sections include legs, columns, feet, finials, pedestals, stretchers, spindles etc. There have been many varieties and fashions over the centuries: baluster, melon, barley-sugar, bobbin, cotton-reel, rope-twist, and so on. Split turning implies a turned section that has been cut in half lengthwise and applied to a cabinet front as a false decorative support.
