A list of monastic institutions upon the river, if we exclude the friars, the hospitals, and such foundations as made part of town or university life, is as follows:—­a priory at Cricklade, another at Lechlade, the Abbey at Eynsham (sufficiently near the stream to be regarded as riparian), the Nunnery and School of Godstow, the great Abbeys of Osney and Rewley, the Benedictine Nunnery at Littlemore, the great Abbey of Abingdon, the Abbey of Dorchester, Cholsey (but this had been destroyed before the Conquest, and was never revived), the Augustinian Nunnery at Goring, the great Cluniac Abbey at Reading, the Cell of Westminster at Hurley, the Abbey of Medmenham, the Abbey of Bisham just opposite Marlow, and the Nunnery of Little Marlow; the Nunnery of Burnham, which, though nearly a mile and a half from the stream, should count from the position of its property as a riparian foundation, the little Nunnery of Ankerwike, the great Benedictine Abbey of Chertsey, the Carthusians of Sheen, and the Benedictines of Westminster, to which may be added the foundation of Bermondsey.

When the end came the total number of those in control of such wide possessions was small.

Indeed it was perhaps no small cause of the unpopularity, such as it was, into which the same monasteries had locally fallen, that so much economic power was concentrated in so few hands.  The greater foundations throughout the country possessed but a little more than 3000 religious, and even when all the nuns, friars, and professed religious of the towns are counted, we do not arrive at more than 8000 in religion in an England which must have had a population of at least 4,000,000, and quite possibly a much larger number; nor could the mobs foresee that the class which would seize upon the abbey lands would concentrate the means of production into still fewer hands, until at last the mass of Englishmen should have no lot in England.

Moreover, it would be an error to consider the numbers of the religious alone.  The smaller foundations, and especially the convents of nuns, did certainly support but small numbers, and this probably accounts for the ease with which they were suppressed, but, on the other hand, their possessions also were small.  In the case of the great foundations, though one can count but 3000 monks and canons, the number of them must be multiplied many times if we are to arrive at the total of the communities concerned.  Reading, Abingdon, and the rest were little cities, with a whole population of direct dependants living within the walls, and a still larger number of families without, who indirectly depended upon the revenues of the abbey for their livelihood.

Another and perhaps a better way of presenting to a modern reader the overwhelming economic power of the mediaeval monastic system, especially its economic power in the Valley of the Thames, would be to add to such a list of houses a map of that valley showing the manors in ecclesiastical hands, the freeholds and leaseholds held by the great abbeys, in addition to the livings that were within their gift; in a word, a map giving all their different forms of revenue.
