To suppose, however, that Celtic monasteries were large, solid structures of stone with cloisters, refectories, dortors and the like is to mistake the economic conditions of the period and of the countries under review. To associate the Celtic bishop with a durable and spacious cathedral church is almost as grotesque an anachronism as to represent St. Lucy (who died in the year 303), as they do in the sailors’ church at Naples, apparelled in a modern court dress with a tiara of gems and a necklace of beautiful pearls.
The Celtic monastery has been compared to a pioneer settlement. It consisted of a congeries of detached cells, each suitable for the habitation of one or more monks. The cells, like the churches of the period, were commonly of wood, sometimes of stone. It is therefore, after the lapse of so many centuries, usually futile to seek for traces of them. Of existing Christian remains of the Celtic period in Cornwall the most noteworthy and interesting are the granite crosses and those monuments especially which bear the Chi-rho monogram. The chapels at Perranzabuloe, at Gwithian and at Madron are also of this date, the two former probably owing their preservation to the sand which buried them and the latter to the healing virtues of the waters of the holy well which flow through it.[54]
Having shown that the Celtic conception of episcopal jurisdiction was definitely monastic, as opposed to the Roman which, at an early period, had become diocesan, it is necessary to fix approximately the date at which, in Cornwall, the former gave place to the latter. Upon the solution of the problem depends the character to be assigned to the four Celtic bishops, Kenstec, Conan, Daniel and Comoere, whose names are disclosed in certain authentic documents and are given in the Truro Diocesan Kalendar.
In Brittany, a more progressive country and less isolated than Cornwall, the change was violently effected by the patriot Nominoë in the year 849. In Ireland the diocesan system was not adopted until 1152.[55] Wales submitted to the jurisdiction and discipline of Canterbury in 1207. It is certain, therefore, that Cornwall, more opposed to Saxon influence than any of the others, did not accept the diocesan system until the days of Egbert (836). There is good reason to believe that the change took place much later. Kenstec’s letter to Archbishop Ceolnoth (833-870) states explicitly that his bishopric was monastic (_Ego Kenstec_ ... [ad] _episcopalem sedem in gente Cornubia in monasterio quod lingua Brettonum appellatur Dinuurin electus, etc._).[56]
