A door

door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a doorway or portal. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a buildingroom, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing.

The door may be able to move in various ways (at angles away from the doorway/portal, by sliding on a plane parallel to the frame, by folding in angles on a parallel plane, or by spinning along an axis at the center of the frame) to allow or prevent ingress or egress. In most cases, a door's interior matches its exterior side. But in other cases (e.g., a vehicle door) the two sides are radically different.

Many doors incorporate locking mechanisms to ensure that only some people can open them (such as with a key). Doors may have devices such as knockers or doorbells by which people outside announce their presence. (In some countries, such as Brazil, it is customary to clap from the sidewalk to announce one's presence.) Apart from providing access into and out of a space, doors may have the secondary functions of ensuring privacy by preventing unwanted attention from outsiders, of separating areas with different functions, of allowing light to pass into and out of a space, of controlling ventilation or air drafts so that interiors may be more effectively heated or cooled, of dampening noise, and of blocking the spread of fire.

Doors can have aestheticsymbolicritualistic purposes. Receiving the key to a door can signify a change in status from outsider to insider.[1] Doors and doorways frequently appear in literature and the arts with metaphorical or allegorical import as a portent of change.

History

The earliest recorded doors appear in the paintings of Egyptian tombs, which show them as single or double doors, each of a single piece of wood. People may have believed these were doors to the afterlife, and some include designs of the afterlife. In Egypt, where the climate is intensely dry, doors were not framed against warping, but in other countries required framed doors—which, according to Vitruvius (iv. 6.) was done with stiles (sea/si) and rails (see: Frame and panel), the enclosed panels filled with tympana set in grooves in the stiles and rails. The stiles were the vertical boards, one of which, tenoned or hinged, is known as the hanging stile, the other as the middle or meeting stile. The horizontal cross pieces are the top rail, bottom rail, and middle or intermediate rails.

The most ancient doors were made of timber, such as those referred to in the Biblical depiction of King Solomon's temple being in olive wood (I Kings vi. 31–35), which were carved and overlaid with gold. The doors that Homer mentions appear to have been cased in silver or brass. Besides olive wood, elmcedaroak and cypress were used. Two doors over 5,000 years old have been found by archaeologists near Zürich, Switzerland.[2] [3]


Stone door in Hampi (India)

A massive door socket from Persepolis (modern-day Iran)

Ancient doors were hung by pintles at the top and bottom of the hanging stile, which worked in sockets in the lintel and sill, the latter in some hard stone such as basalt or granite. Those Hilprecht found at Nippur, dating from 2000 BC, were in dolerite. The tenons of the gates at Balawat were sheathed with bronze (now in the British Museum). These doors or gates were hung in two leaves, each about 2.54 m (100 in) wide and 8.2 m (27 ft) high; they were encased with bronze bands or strips, 25.4 cm (10.0 in) high, covered with repoussé decoration of figures. The wood doors would seem to have been about 7.62 cm (3.00 in) thick, but the hanging stile was over 360 millimetres (14 in) diameter. Other sheathings of various sizes in bronze show this was a universal method adopted to protect the wood pivots. In the Hauran in Syria where timber is scarce, the doors were made of stone, and one measuring 1.63 by 0.79 m (64 by 31 in) is in the British Museum; the band on the meeting stile shows that it was one of the leaves of a double door. At Kuffeir near Bostra in Syria, Burckhardt found stone doors, 2.74 to 3.048 m (8.99 to 10.00 ft) high, being the entrance doors of the town. In Etruria many stone doors are referred to by Dennis.


Roman folding doors at Pompeii, from the first century AD, similar with Neoclassical doors from the 19th century

Ancient Greek and Roman doors were either single doors, double doors, triple doors, sliding doors or folding doors, in the last case the leaves were hinged and folded back. In the tomb of Theron at Agrigentum there is a single four-panel door carved in stone. In the Blundell collection is a bas-relief of a temple with double doors, each leaf with five panels. Among existing examples, the bronze doors in the church of SS. Cosmas and Damiano, in Rome, are important examples of Roman metal work of the best period; they are in two leaves, each with two panels, and are framed in bronze. Those of the Pantheon are similar in design, with narrow horizontal panels in addition, at the top, bottom and middle. Two other bronze doors of the Roman period are in the Lateran Basilica.
