The chief difficulty of starting again the machine of civilisation when its parts have been distorted by a barbarian interlude, whether external or internal in origin, is the accumulation of capital. The next difficulty is the preservation of such capital in the midst of continual petty feuds and raids, and the third is that general continuity of effort, and that treasuring up of proved experience, to which a barbaric time, succeeding upon the decline of a civilisation, is particularly unfitted. For the surmounting of all these difficulties the monks of Western Europe were suited to a high degree. Fixed wealth could be accumulated in the hands of communities whose whole temptation was to gather, and who had no opportunity for spending in waste. The religious atmosphere in which they grew up forbade their spoliation, at least in the internal wars of a Christian people, and each of the great foundations provided a community of learning and treasuring up of experience which single families, especially families of barbaric chieftains, could never have achieved. They provided leisure for literary effort, and a strict disciplinary rule enforcing regular, continuous, and assiduous labour, and they provided these in a society from which exact application of such a kind had all but disappeared. The monastic institution, so far as Western Europe was concerned, was comparatively young when the work in Britain was begun. The fifth century had seen its inception; it was still embryonic in the sixth; the seventh, which was the date of its great conquest of the English country-sides, was for it a period of youth and of vigour as fresh as was, let us say, the thirteenth century for the renaissance of civil learning. We must not think of these early foundations as we think of the complicated, wealthy, somewhat restricted and privileged bodies of the later Middle Ages. They were all more or less of one type, and that type a simple one. They all sprang from the same Benedictine stem. It was the quality of all to be somewhat independent in management, and especially to work in large units, and out of the very many which sprang, up all over the island three particularly concern the Thames Valley. Each of them dates from the very beginnings of Anglo-Saxon history, each of them has its roots in legend, and each of them continued for close upon a thousand years to be a capital economic centre of English life. These three great Benedictine foundations are WESTMINSTER, CHERTSEY, and ABINGDON.
