Facing you in the middle of the vestibule are double or folding doors, more or less ornate with bronze, ivory, and other work, and generally bearing a large ring or handle to serve either as a knocker or to pull the door to. Above them is a bronze grating or fretwork for further adornment and to admit light and air. Some householders, more superstitious or conventional than the rest, affected an inscription, such as "Let no evil enter here," and over some humbler entrance you might find a cage containing a parrot or magpie, which had been trained to say "Good luck to you" in Greek. At either side of the door, or of the actual entrance to the vestibule, is a column or pilaster, either made of timber and cased with other woods of a more beautiful and costly kind, or consisting of coloured marble with an ornate capital. These "doorposts" were wreathed with laurel or other foliage on festal occasions, such as when the occupant had won some distinguished honour in the field, in the courts, or at the elections, or when a marriage took place from within. At funerals small cypress trees or branches would be placed in and about the vestibule. At one side of it you might sometimes find a smaller door, to be used for the ordinary going in and out when it was unnecessary or inconvenient for the larger doors to be opened. [Illustration: FIG. 30.--ENTRANCE TO HOUSE OF PANSA. (Pompeii.)] The doors themselves turn, not upon hinges of the modern kind, but upon pivots, which move, often too noisily, in sockets let into the threshold and lintel. The fastenings consisted of locks--often highly ingenious--of a bar laid across from wall to wall, of bolts shot across or upward and downward, and sometimes of a prop leaning against the inside of the door and entering a cavity in the floor of the passage. The floor of the entrance passage itself might be paved with marble tiles, or made simply of a polished cement with or without patterns worked in it; or it might consist of small cubes of stone, white and black or more variously coloured, frequently worked into figures, and now and then accompanied by an inscription just within the threshold, such as "Greeting" or "Beware the Dog." In one Pompeian house the floor bears the well-known mosaic likeness of a dog held upon its chain. At the side of the passage there is often a smaller room for the janitor. When there is none, he must be supposed to have used a movable seat.
