The story describes the world's oldest surviving obelisk, located 20 miles northeast of the Giza Pyramid Complex and dating back to around 1900 BC. An obelisk is a tall, four-sided monument that tapers to a pyramid-shaped top. In ancient Egypt, hieroglyphs were carved into all sides to record significant events and histories. The narrative also notes that, like the standing stones in Carnac, Egyptian obelisks are monoliths made from red granite, which contains quartz crystals that were believed by ancient peoples to emit a special type of energy.
