A chandelier is a branched decorative ceiling-mounted light fixture with two or more arms bearing lights. Chandeliers are often ornate, containing dozens of lamps and complex arrays of glass or crystal prisms to illuminate a room with refracted light.

The word Chandelier appeared in the English language in the late 14th Century, directly from the 12th Century Old Spanish world Chandelier this was a new spelling of the earlier 10th Century French word Chandelabre which in turn comes from Latin Candelbrum from the Latin Candela meaning candle. The word candle then in turn has its own etymology.

The earliest candle chandeliers were used in medieval times by the wealthy. They generally took the form of a wooden cross with a number of spikes on which candles could be secured, the whole assembly being hoisted to a suitable height on a rope or chain suspended from a hook.

From the 15th century, more complex forms of chandeliers based on ring or crown designs began to become popular decorative features, found in palaces and homes of the nobility, clergy and merchant class. The high cost of night time illumination made the chandelier a symbol of luxury and status. By the early 18th century, ornate cast ormolu forms with long, curved arms and many candles could be found in the homes of much of the growing merchant class. Neoclassical motifs became an increasingly common element, mostly in cast metals but also in carved and gilded wood. Developments in glassmaking in the 18th century allowed the cheaper production of lead crystal. The light-scattering properties of this highly refractive glass quickly became a popular addition to the form, leading to the crystal chandelier.
