Some years ago, we went on an extraordinary journey down the Nile. I have been fascinated by Egypt since I was a teenager so this cruise was a dream come true. Amongst all the wonders, we came across was this rather pedestrian-looking well. However it was explained to us that what the purpose of it was to measure the rise and fall of the very life source of Egypt. I quote, ” Given the importance of the Nile flooding  and its regular returns, it is no wonder that the Egyptians began measuring the rise probably even before historic times in order to predict the harvest. At first these records were little more than marks on the river bank, but later marked stairs, pillars or wells were built and records of the measurements kept. The most important nilometer lay on the island of Elephantine, others were built at different times at Philae, Edfu, Khenu, Memphis, Heliopolis, Buto and other places ”http://www.reshafim.org.il/ad/egypt/geography/nile.htm. This particular Nile metre is at Kom Ombo in the south near Aswan.
