The Rosetta Stone was inscribed in 196 BCE with the same content in Classical Greek, Demotic, and Hieroglyphic text. It is on display in the British Museum. The sign in figure 1 was created in the 21st Century with the same content in Chinese, Pictogram, Portuguese, and English. It was temporally posted at a holiday light display in the Chinese territory of Taipa. A similar sign (figure 2) is permanently posted at an electrical power substation in Arizona. This sign contains the same content in English, Pictogram, and Spanish.
Comparing the effects of the electrical bolts on the two pictograph people show that holiday light displays in Taipa may be more dangerous than electrical power substations in Arizona. On the other hand, pictogram people may just be more sensitive to Taipa electricity (220 V, 50 Hz) than to Arizona electricity (110V, 60 Hz). An older version of figure 2 is shown in figure 3. The new version clarifies what an electrical bolt looks like so victims can know for sure what hit them.
