In ancient Egypt, iron was known to be "the metal from heaven" . Iron was often used in tools, weapons, jewelry, and other fine items associating iron with power and royalty.
An sample advertisement could have been something along the lines of, "Treat yourself like a deity and drape yourself in the metal from heaven".
The examples of art that I feel best communicated the rulers' power to their people, were the sculptures and architecture made by the civilization of ancient Egypt. The art of Ancient Egypt represented many social, economic and religious processes that happened at that time, and among them were many representations of Pharaoh's power leadership qualities, like wisdom, stability, strenght, and power. Many sculptures and temples were monumental and magnificent. These pieces of art had a great effect on public opinion about Pharaohs. Pyramids and temples that Pharaoh's had built had a tremendous and long-term impact on citizens of Ancient Egypt since they've represented Pharaohs as godlike creatures whose wisdom, wealth and prosperity will be preserved in the afterlife. Temple of Hatshepsut, Pyramid of Djoser, Luxor Temple, Colossi of Memnon and The Great Sphinx Of Giza are the best examples of art that communicated Pharaoh's wisdom, strength, and power.
