These were the main buildings, the essential buildings of a monastery great or small. Where a monastery was rich enough to indulge in luxuries of "modern improvements and all the best appliances," there was hardly any limit to the architectural freaks that might be indulged in. There were the infirmary and the hospital; the calefactory or warming apparatus, the recreation hall and the winter hall, the locutorium and the common hall, and I know not what besides. You observe I have as yet said nothing about the library. I must remind you that in the thirteenth century the number of books in the world was, to say the least, small. A library of five hundred volumes would, in those days, have been considered an important collection, and, after making all due allowances for ridiculous exaggeration which have been made by ill-informed writers on the subject, it may safely be said that nobody in the thirteenth century--at any rate in England--would have erected a large and lofty building as a receptacle for books, simply because nobody could have contemplated the possibility of filling it. Here and there amongst the larger and more important monasteries there were undoubtedly collections of books, the custody of which was intrusted to an accredited officer; but the time had not yet come for making libraries well stored with such priceless treasures as Leland, the antiquary, saw at Glastonbury, just before that magnificent foundation was given as a prey to the spoilers. A library, in any such sense as we now understand the term, was not only no essential part of a monastery in those days, but it may be said to have been a rarity.
