History of communication – What can rock art tell us about communication?
Rock art was one of the earliest forms of communication. Rock art are any human made markings made on natural stone. Rock art can also be described or known as “Rock drawings” and “rock paintings”. There are two types of rock art Petroglyphs and Pictographs. Petroglyphs are carvings into stone surfers by starching, pecking, drilling and sculpting. Pictographs are rock and cave paintings by using clay or hematite with other oxides, usually painted one with their finger. There are quite a lot of technical difficulties when dating rock art, which sometimes makes it difficult to determine the correct date and year. One of the earliest forms of rock art was discovered in Arnhem Land in northern Australia and is estimated to be over 60,000 years old (aboriginal art online 2004). Australia dose not have the oldest know rock art, India holds that title at such sites as Auditorium Cave and Daraki-Chattan. Australian rock art is know to be one of the most expensive to purchase as they show some of the oldest know artistic images.
