“People have been diving ever since primitive man was forced to collect food from the sea,” says HawaiiScubaDiving.com (“History of Scuba Diving”, HawaiiScubaDiving.com Internet). Man has always been curious about the underwater world and has sought to explore it. This drove man to come up with new ways to extend his reach into the underwater world and to make the trip less difficult. Over time underwater exploration has been made easier due to man’s passion for exploring a fascinating new underwater world. Inventions such as regulators, self-contained breathing apparatuses, oxygen tanks, neoprene suits, and many more technologies have been used to make underwater exploration as easy and efficient as possible. Scuba diving has evolved into a wide range of advanced technology for the average person to explore a whole new underwater world.
People have been diving since about 4500 BC. Greeks, Mesopotamians, Chinese, and many others dove for food, commerce, and warfare (Cooper). Searching the sea bed for food was the main reason that drove people to dive. Modern man knows this because ancient drawings depict people diving. Ancient artifacts have been discovered in Greece that show divers partaking in military endeavors and searching the ocean floor for sponges (“History of Scuba Diving”, ScubaSoul.com Internet). In 414 BC, the first record of diving being used in warfare was in the siege of Syracuse by Greeks. “The origins and history of scuba diving can be traced back centuries. Before the apparatus for the sport was invented, men and women had practiced holding their breath while being submerged underwater”, says Ed J. Price, a diver from scubasoul.com (“History of Scuba Diving”, ScubaSoul.com Internet).
Primitive diving inventions were effective but had their issues and problems as well. Naked divers have been documented, such as Greeks who could hold their breath under water while searching for and collecting sponges, but the use of a mechanical device as an air supply for diving is harder to accurately date (Ecott Internet). One of the first methods of underwater breathing was long air hoses that extended down from the surface so divers could breathe through them. These were mentioned by 77 AD by Plinius the Elder. Another device used for diving was the dive bell. In 360 BC the dive bell was mentioned in Aristotle’s writings (“History of Scuba Diving”, HawaiiScubaDiving.com Internet). The dive bell was a hollow object shaped like a bell or cylinder that held air inside as it was guided down underwater. This device did work, but if the dive was long, carbon monoxide would build up in the dive bell and poison the diver (Cooper). Alexander the Great was said to have dove in a dive bell that was glass and barrel-shaped during the siege of Tyre, but this is debated because of the lack of technology available to build it at the time. Niccolo Tertaglia designed an hourglass with a wooden frame to be used for diving, but it was never...
