It may possibly be open to doubt whether the dignified appellation of architecture should be applied to buildings of the kind we have just been describing; but when we come to the series of remains of the twelfth dynasty at Beni-Hassan, in middle Egypt, we meet with the earliest known examples of that most interesting feature of all subsequent styles--the column. Whether the idea of columnar architecture originated with the necessities of quarrying--square piers being left at intervals to support the superincumbent mass of rock as the quarry was gradually driven in--or whether the earliest stone piers were imitations of brickwork or of timber posts, we shall probably never be able to determine accurately, though the former supposition seems the more likely. We have here monuments of a date 1400 years anterior to the earliest known Greek examples, with splendid columns, both exterior and interior, which no reasonable person can doubt are the prototypes of the Greek Doric order. Fig. 14 is a plan with a section, and Fig. 15 an exterior view, of one of these tombs, which, it will be seen, consisted of a portico, a chamber with its roof supported by columns, and a small space at the farther end in which is formed the opening of a sloping passage or well, at the bottom of which the vault for the reception of the body was constructed. The walls of the large chamber are lavishly decorated with scenes of every-day life, and it has even been suggested that these places were not erected originally as tombs, but as dwelling-places, which after death were appropriated as sepulchres.
