When were bells first made? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? When were bells first made? The bell is a percussion instrument: the musical sound in it is produced by striking. And since the earliest musical instruments were percussion instruments, bells of one kind or another can be considered one of the first human musical instruments. It is impossible to trace their history: it goes too far back. For example, more than 4 thousand years ago, the Chinese had an instrument consisting of 16 flat stones suspended on a frame, and when they were hit with a wooden mallet, a whole range of exotic sounds arose. Of course, in our view, the bells must be made of some kind of metal. It is assumed, for example, that King Solomon had large golden bells on the roof of his temple to disperse the birds. The ancient Greeks and Romans had bells of all kinds, including pocket bells. In Athens, they were used by the priests, and in Sparta, when the king died, women paraded through the streets, striking small bells. Bronze bells were discovered during the excavations of Nineveh, which was destroyed around 612 BC. e. And small bells, like modern bells, were found in Peru in ancient burial grounds, which are about 1500 years old. The development of the bell from its primitive form proceeded in two directions: east and west. In the East, it developed into forms that can be conditionally called "cauldron" and "bowl". The thicket became the gong, which is an exclusively oriental instrument. The cauldron developed into barrel bells: Chinese and Japanese. In Western civilization, the bell evolved into a "bowl" shape. Later, it was supplemented with a tongue, so that it could now be hit from the inside. A large copper or bronze bowl mounted upside down under the dome of a church first appeared around 400 BC. The bronze bells in use today are 80 percent copper and 20 percent bronze. Author: Likum A. Random interesting fact from the Great Encyclopedia: Why is lava hot? The earth in the center is a very hot place. If we could get closer to the center of the Earth at 48 km, the temperature there would be 1200 degrees Celsius. At the core, or center, of the Earth, the temperature reaches 5500 degrees Celsius. At this temperature, the stone exists in a molten state. Lava is molten rock mixed with steam and gas that erupts with force from the bowels of the Earth. It breaks from the center of the Earth through cracks in the crust. Sometimes cracks are round. Then the lava comes out through them, spills into a round puddle and freezes in the shape of a mountain. If the lava erupts again, it builds up on the first eruption and makes the mountain taller. If the eruptions are repeated, layer after layer is superimposed, a mountain is formed, called a volcano. When lava erupts and spills over the Earth, it destroys everything in its path. This happens because the rapid flow of molten stone has a temperature of 1090 to 1640 degrees Celsius. Cities that are located close to volcanoes are always in danger of being destroyed in the event of a lava eruption. Sometimes this does not happen for a long time and people believe that they are safe forever. And then suddenly the eruptions start again. This happened two millennia ago with the Italian city of Pompeii. It was completely buried under a lava flow and a layer of ash from Mount Vesuvius.
