A cedar lyre-back swivel seat desk-chair by Andrew Lenehan,…

• 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.
• Castors - Wheels, fitted especially to chair legs, couches, tables and some smaller pieces of furniture, to enable them to be easily moved about. The earliest castors were of brass, with shanks fitting into the base of the leg, and the wheels often made of leather. In the late 18th century, brass 'bucket' or 'cup' castors were introduced, either rounded or square, fitting directly over the end of the leg and held in place with screws. The wheels were generally solid brass. Bucket/cup castors continued in use throughout the 19th century and indeed are still made today. In the later 19th century wheels were sometimes made of wood, china, either white or brown, and sometimes of steel.
• Lyre - Attributed to the 18th century designer Robert Adam, the back splat of a chair or sthe supports of a table are in the form of a lyre, a Greek musical instrument similar to a harp.
  
  In shape it resembles two reversed scrolls.
  
  Chairs continued to be made in this style for at least the next fifty years.
  
  In Australia many cedar chairs and tables have survived dating to the 1830s and 1840s, featuring the lyre shape in the back splats and as supports for small tables.
• Signed or Stamped - A signed piece of furniture may mean that the maker has signed (and hopefully dated) the piece in the same way that we sign a cheque, but more likely, that it bears evidence of the name of the maker, wholesaler or retailer as a paper label, metal plaque, impressed into the timber or in later pieces after about 1880, stamped onto the timber with an ink stamp.
  
  The 'signature' or stamp will always be in an unobtrusive position: under the top of a table, on the underside of the rails of a chair, inside a drawer or on the back.
  
  The fact that a piece is 'signed' considerably enhances its value. Signed Australian furniture is extremely rare, and for imported furniture, it is a mark of quality of the item, as only the items by the top makers or retailers were 'signed'
• Lyre Motif - The lyre motif is an ancient decorative design that is believed to have originated in ancient Greece, where the lyre was a popular musical instrument. The lyre itself was often decorated with ornate carvings and designs, including the iconic lyre motif.
  
  In ancient Greek mythology, the lyre was associated with the god Apollo, who was the patron of music and the arts. The lyre was said to have been invented by the god Hermes, who presented it to Apollo as a gift. As a result, the lyre became a symbol of creativity, inspiration, and artistic expression.
  
  The lyre motif typically features a curved or S-shaped body, with strings extending upwards from the base. The motif was often used in architectural decoration, as well as on pottery, jewellery, and other decorative objects.
