The man went to another tribe, where he again began to show them the value of his invention. People were interested there too, a bit too interested for the peace of mind of their leaders, who began to notice that the man was drawing crowds. So they decided to do away with the man. They poisoned him, crucified him, put it any way you like. Afterwards they were afraid that the people might turn against them, but the leaders were very wise. Do you know what they did? The leaders had a portrait of the man made and mounted it in a building constructed just for the portrait. The instruments for making fire were placed in front of the portrait, and the people were taught to revere the portrait and pay reverence to the instruments of fire, which they dutifully did for centuries. The veneration and the worship went on, but there was no fire.
