The chieftain's hall is twice the size and value of the free tribesman's, and the free tribesman's is twice [p241] that of the taeog. But the plan is the same. They are all built with similar green timber forks and roof-tree and wattle,[319] with the fireplace in the nave and the rush beds in the aisles. One might almost conjecture that as the tabernacle was the type which grew into Solomon's temple, so the tribal house built of green timber and wattle, with its high nave and lower aisles, when imitated in stone, grew into the Gothic cathedral. Certainly the Gothic cathedral, simplified and reduced in size and materials to a rough and rapidly erected structure of green timber and wattle, would give no bad idea of the tribal house of Wales or Ireland. It has been noticed in a former chapter that the Bishop of Durham had his episcopal bothy, or hunting hall, erected for him every year by his villeins, in the forest, as late as the time of the Boldon Book. This also was possibly a survival of the tribal house.[320] «The tribal household.» In this tribal house the undivided household of free tribesmen, comprising several generations down to the great-grandchildren of a common ancestor, lived together; and, as already mentioned, even the structure of the house was typical of the tribal family arrangement. In the aisles were the _gwelys_ of rushes, and the whole household was bound as it were together in one _gwellygord_. The _gwelys_ were divided by the [p242] central columns, or _gavaels_ (Welsh for 'fork'), into four separate divisions; so there were four _gavaels_ in a trev, and four randirs in a gavael. And so in after times, long after the tribal life was broken up, the original holding of an ancient tribesman became divided in the hands of his descendants into _gavells_ and _gwelys_, or _weles_.[321] Another point has been noticed. In the old times, when the tribesmen shifted about from place to place, their personal names by necessity could not be given to the places or tyddyns they lived in. The local names in a country where the tribal system prevailed were taken from natural characteristics--the streams, the woods, the hills, which marked the site. This was the case, for instance, with the townlands and _tates_ of Ireland. Most of them bear witness, as we have seen, by their impersonal names, to the shifting and inconstant tenancy of successive tribesmen.[322] It was probably not till the tribes became stationary, and, after many generations, the same families became permanent holders of the same homesteads, that the Welsh _gwelys_ and _gavells_ became permanent family possessions, known by the personal name of their occupants, as we find them in the extents of the fourteenth century.[323] «The tribal blood-money.»
