It is built, like the houses observed by Giraldus Cambrensis, of trees newly cut from the forest.[314] A long straight pole is selected for the roof-tree. Six well-grown trees, with suitable branches apparently reaching over to meet one another, and of about the same size as the roof-tree, are stuck upright in the ground at even distances in two parallel rows--three in each row. Their extremities bending over make a Gothic arch, and crossing one another at the top each pair makes a fork, upon which the roof-tree is fixed. These trees supporting the roof-tree are called _gavaels_, _forks_, or _columns_,[315] and they form the nave of the tribal house. Then, at some distance back from these rows of _columns_ or _forks_, low walls of stakes and wattle shut in the _aisles_ of the house, and over all is the roof of branches and rough thatch, while at the ends are the wattle doors of entrance. All along the aisles, behind the pillars, are placed beds of rushes, [p240] called _gwelys_ (_lecti_), on which the inmates sleep. The footboards of the beds, between the columns, form their seats in the daytime. The fire is lighted on an open hearth in the centre of the nave, between the middle columns, and in the chieftain's hall a screen runs between these central pillars and either wall, so partially dividing off the upper portion where the chief, the edling, and his principal officers have their own appointed places, from the lower end of the hall where the humbler members of the household are ranged in order.[316] The columns, like those in Homeric houses and Solomon's temple, are sometimes cased in metal, and the silentiary, to call attention, strikes one of them with his staff. The bed or seat of the chieftain is also sometimes covered by a metal canopy.[317] In his hand he holds a sceptre or wand of gold, equal in length to himself, and as thick as his little finger. He eats from a golden plate as wide as his face, and as thick as the thumb-nail of a ploughman who has handled the plough for seven years.[318] The kitchen and other outbuildings are ranged round the hall, and beyond these again are the corn and the cattle-yard included in the _tyddyn_. «Likeness of the tribal house to the Gothic cathedral.»
