ABSTRACT
Writing a history is a bit like producing an estimate, it is hard to do without putting a boundary around the subject. Like an estimate we need to know what is going to be included in the history and what is to be excluded or not going to be covered. For example, the Bible has the most commonly quoted and earliest references to estimating, ‘For which of you, intending to build a tower, does not first sit down and estimate the cost, to see whether he has enough to complete it?’ which appears in the New Testament (Luke 14:28). So estimating has been acknowledged as a worthy pursuit by some of the earliest stone masons and craftsmen. In this chapter I intend to focus on more recent history.
