Windsor, as he passed, stood up above the right of him, not very different from what we still admire as we come down from Bray and look up to the jutting fore-tower which is worthy of Coucy. But down below Windsor (after whose bridge we to-day see nothing whatever of value), just after he had passed the wooden bridge of Staines and shot the weir of that town, the river bent southward. The traveller would have found Pentonhook already forming or formed, and when he had got round it he would have seen soaring above him down stream the great mass of Chertsey Abbey. If Reading had the solidity and the barbaric grandeur of Durham, Chertsey had in an ecclesiastical way the vastness of Windsor, and must have seemed like a town to anyone approaching it thus down the river. The enclosed area of the abbey buildings alone covered four acres. This impression which such a traveller would have received of the great religious houses was enhanced by something more than the magnitude and splendour of the buildings. Divided as was opinion at that moment upon their value to the State, and jealous as had become landless men of the long traditions and privileges of the monks, these still represented not only their own wealth but the general accumulation of capital and the continued prosperity of the river valley. It is true to say, in spite of the difficulty of appreciating such a truth in the light of our knowledge of what was to follow, that the destruction of such foundations would have seemed to the traveller before the Dissolution inconceivable. Nevertheless it came. These notes are not the place in which to discuss that most difficult of all historical problems--I mean the causes which led the nation to abandon in a couple of generations the whole of its traditions and to adopt, not spontaneously but at the bidding of a comparatively small body of wealthy men, a new scheme of society. But it is of value to consider the economic aspect of the thing, and to show what it was that Henry desired to seize when his policy of Dissolution was secretly formed. The economic function of the monastic system in the Middle Ages, and especially in the later Middle Ages, is one to which no sufficient attention has been given by historians. They collected, as does no modern agency, wealth from very various sources, scattered up and down the whole of the kingdom, and often farther afield, throughout Europe, and exercised the whole economic power so drawn together in one centre, and so founded a permanent nucleus of wealth in the place where the community resided.
