This is an incomplete idea for a Body Test. The idea is based on the mapping of India by various people including Sir (Colonel) Everest. I'm sure Egyptians had as keen an interest in mapping and measurement. Basically, the idea is to use triangulation from known fixed points to progressively determine position and height of new points. I think Everest & co started from one end of India and dead-reckoned across the country. Maintaining accuracy is a key problem which will depend on good positioning of instruments (theodolites), accuracy of the instruments and accuracy of the resulting calculations. I seem to remember reading that, when Everest did his surveying, he had a large room full of human calculators performing the required regression calculations. His accuracy in determining the height of Mt Everest was incredible.
So I imagine seven magnificent mountains of indeterminate height appearing in Egypt (ok so it's mostly desert but work with me here). The task is to produce the most accurate estimate of the heights of each mountain. Each week, the N most accurate estimates for each mountain gain one skill point. When a player has had most accurate estimates for every mountain then they pass.
Accuracy is determined by a number of factors.
Good positioning of theodolites. This is paramount. The closer together they are then the more accurate the estimates - but it is quicker to work from the coast (I'm assuming some fixed points available on the coast) to the interior with larger distances. Of course, they must be line-of-sight. The placing of theodolites is going to take a lot of running - hence a body test.
Quality of theodolite. This can bring in various skills if appropriate.
Accuracy of calculation. There could be an element of co-operation - the more players you have aiding you in your calculations, the more accurate the height estimates. Maybe in exchange they have access to (a proportion of?) your theodolite measurements which gives some kind of competitive balance.
As I say, an incomplete idea. I guess I was thinking that the ancient Egyptians did a lot of measurements geographically and astronomically and used these in the alignment of pyramids and such. However, at the moment there is no reflection of this type of activity in ATITD.
