Petroglyphs in the context of "Rock art"

The history of communication technologies (media and appropriate inscription tools) have evolved in tandem with shifts in political and economic systems, and by extension, systems of power. Communication can range from very subtle processes of exchange to full conversations and mass communication. The history of communication itself can be traced back since the origin of speech circa 100,000 BCE. The use of technology in communication may be considered since the first use of symbols about 30,000 years BCE. Among the symbols used, there are cave paintings, petroglyphs, pictograms and ideograms. Writing was a major innovation, as well as printing technology and, more recently, telecommunications and the Internet.

In archaeology, cave paintings are a type of parietal art (which category also includes petroglyphs, or engravings), found on the wall or ceilings of caves. The term usually implies prehistoric origin. Several groups of scientists suggest that the oldest of such paintings were created not by Homo sapiens, but by Denisovans and Neanderthals.

Discussion around prehistoric art is important in understanding the history of Homo sapiens and how human beings have come to have unique abstract thoughts. Some point to these prehistoric paintings as possible examples of creativity, spirituality, and sentimental thinking in prehistoric humans.

Sydney rock engravings, or Sydney rock art, comprise a number of Aboriginal rock art sites in the Sydney region, New South Wales, Australia. Carved from Sydney sandstone, they consist of carefully drawn images of people, animals, or symbols. Many thousands of such engravings are known to exist in the Sydney region, although the locations of most are not publicised to prevent damage by vandalism, and to retain their sanctity, as they are still regarded as sacred sites by Aboriginal Australians. There are two art environments in Sydney Basin: rock shelters, and engraving sites.

There are 1,500 pieces of Aboriginal art in Sydney, more than half of which contain rock art, and around 1,500 caves or shelters which contain cultural deposit. They are comparable with the petroglyphs of Native Americans and the rock art found elsewhere in Australia, but have their own distinctive style which is quite unlike rock art found anywhere else in Australia. Dating to around 5,000 years, with some possibly as old as 7,000 years, Sydney rock art is predominantly found in Ku-ring-gai Council, Sydney Harbour and the Blue Mountains.

Oceanic art or Oceanian art comprises the creative works made by the native people of the Pacific Islands and Australia, including areas as far apart as Hawaii and Easter Island. Specifically it comprises the works of the two groups of people who settled the area, though during two different periods. They would in time however, come to interact and together reach even more remote islands. The area is often broken down into four separate regions: Micronesia, Melanesia, Polynesia and Australia. Australia, along with interior Melanesia (Papua), are populated by descendants of the first waves of human migrations into the region by Australo-Melanesians. Micronesia, Island Melanesia, and Polynesia, on the other hand, are descendants of later Austronesian voyagers who intermixed with native Australo-Melanesians; mostly via the Neolithic Lapita culture. All of the regions in later times would be greatly affected by western influence and colonization. In more recent times, the people of Oceania have found a greater appreciation of their region's artistic heritage.

The artistic creations of these people varies greatly throughout the cultures and regions. The subject matter typically carries themes of fertility or the supernatural. Art such as masks were used in religious ceremonies or social rituals. Petroglyphs, Tattooing, painting, wood carving, stone carving and textile work are other common art forms. Contemporary Pacific art is alive and well, encompassing traditional styles, symbols, and materials, but now imagined in a diversity of contemporary forms, revealing the complexity of geographic, cultural and individual interaction and history.

Montezuma County is a county located in the southwest corner of the U.S. state of Colorado. As of the 2020 census, the population was 25,849. The county seat is Cortez. Montezuma County contains many archaeologically significant Amerindian structures, which notably can be found in Mesa Verde National Park, Canyons of the Ancients National Monument, Yucca House National Monument, and Hovenweep National Monument. Montezuma County is also home to most of the Ute Mountain Indian Reservation, home of the Weeminuche Band of the Ute Nation, known as the Ute Mountain Ute Tribe, with its headquarters at Towaoc.
