The idea of a circle as a symbol and a metaphor has been commonly used, almost to the point of cliché. Despite that, I am going to use it anyway.
In crime scene processing, one search pattern that may be employed is the spiral search. This means starting from one focal point and walking in circles around it, widening the diameter as you go along. One reason why this pattern may be used is because the focal point denotes an area where an important event occurred, so evidence is expected to be scattered around this focal point. Another advantage to this search technique is that by circling around an area, you are able to see things from different perspectives, potentially catching something you may have missed from one point of view.
Similarly, the past two months have seen me return to many old themes with a new perspective. In April, I returned to Canada and to UTM; I resumed my data collection in London in St. Bride’s Church; and in May I once again participated in the School of Archaeology’s Distance Learning course. But my role in each event was very different than before, and gave me some new perspectives into my work.
