The angular profile of the Obelisk inside the Karnak temple

The Obelisk is one of the most famous symbols of ancient Egypt (along with other symbols such as the Pyramids, etc). Obelisks were typically erected by pharaohs at the entrance to the temples, but over a period of time, many of the obelisks were taken away and are now present in cities over the world (and are part of the tourist attraction of these cities). This photo shows the angular profile of an Obelisk and shows how smooth the Obelisk would have been when it was created (since it seems very smooth in sections right now).
