The Egyptians built the pyramids in 2700 B.C. as homes for dead pharaohs, and their building technology was unparalleled until the mid-nineteenth century. Egyptian images do not indicate that slave labor was used to create these enormous buildings, but modern society still has not figured out how the pyramids were created. Egyptians also created immortal images by carving hieroglyphs into stone. It took until the late nineteenth century to realize that the hieroglyphs were phonetic symbols of a dead spoken language. Having never developed perspective, Egyptians focused on actual, unchanging physical dimensions.
