Visiting the ruins of Abbeys, Priories etc always raises the question of what it was actually like to live there at those times. The official guide books often do a good job at stating the headline facts i.e. the monks ate here, slept there, etc etc but don't give an idea of what it was really like. This book takes things a step further and attempts to build a picture of what it was like day-to-day in an (semi-) enclosed environment. OK, so the Rule of St Benedict is the set of guidelines but what was the reality? After all what has really changed since medieval times - not people, just the "stuff" that surrounds us, so did the monks and nuns get bored, jealous, crabbit, rather over-excited, etc and try to murder each other, go hawking, visit the pub, try to out-do each other...... of course they did!
The author appears to justify every sentence in the book with frequent references to an extensive range of contemporary documents. There is a small amount of (inevitable) repetition, but this means that it's possible to read the book out of chapter sequence if you have an interest in one particular topic and wish to look at that section first. This is probably about as far as it's possible to go without verging into fiction to fill the gaps.
This book goes into detail regarding diet, family, daily regime, medical problems (mental and physical), clothes, travel, and basically the pros and cons of monastic life at those times. Therefore, in summary, it does exactly what it sets out to do and is a very interesting read.
