Louis XIII Oak Bookcase with Barley Twist Pillars

• Arabesque - The arabesque pattern is an ornamental design that features flowing, curving lines and elaborate geometric shapes. It is inspired by the art and architecture of the Islamic world and was developed at Fontainebleu France in the mid 16th century. Its use was spread through published engravings, and it is characterized by its intricate and highly decorative nature. The arabesque pattern is created using a repetitive motif that is repeated and interwoven to create a cohesive design. It was used as a form of decoration in art, architecture, textiles, pottery, furniture and ceramics and it is often used to add a sense of grandeur and sophistication to a design. The arabesque pattern is admired for its beauty and complexity, and it continues to be used in a wide range of decorative contexts today.
• Breakfront - A design generally found in larger pieces of furniture, such as bookcases, wardrobes and some sideboards. The line of the front is interrupted by the middle section standing out from each end. In a reverse breakfront, the centre section is recessed behind each end. Breakfronted pieces are usually made in three sections the middle and the two wings which are held together by the cornice and pediment, and the plinth on which it stands. The sensible buyer should show caution before buying breakfront pieces, especially bookcases, which are highly desirable and expensive. Always check that the timber, colour, patination, backboards, decoration and thickness of the wood are same in each section.
• 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.
• Pediment - The uppermost section of a tall usually double-heightened piece of cabinet furniture, surmounting the cornice. The pediment can take a variety of forms derived from the architecture of classical antiquity. A broken pediment is of triangular shape, however, the two raised sides do not meet at the apex but are 'broken' the gap between them often ornamented with an urn or finial. Swan-neck pediments are of similar form, although the uprights are gracefully arched, resembling a swan's neck. They are often found, for example, on longcase clocks.
• Cornice - The upper section of a high piece of furniture such as a bookcase, wardrobe or cabinet that sits immediately on the main structure. The cornice is usually decorated with a variety of architectural mouldings, worked either with a moulding plane or, from the later 19th century, by machine. The front and side of the cornice are mitred together, strengthened by glue blocks, and the back is generally a simple dovetailed rail to hold the structure together. Cornices are generally, though not always, fitted separately to the piece and are held in place either by screws sunk into the top board or by wooden corner blocks. A pediment may sit above the cornice, but sometimes the terms cornice and pediment are used interchangeably.
• 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.
