Iraq, officially the Republic of Iraq, is a country in West Asia. Located within the geo-political region of the Middle East, it is bordered by Saudi Arabia to the south, Turkey to the north, Iran to the east, the Persian Gulf and Kuwait to the southeast, Jordan to the southwest, and Syria to the west. The country covers an area of 438,317 square kilometres (169,235 sq mi) and has a population of over 46 million, making it the 58th largest country by area and the 31st most populous in the world. Baghdad, home to over 8 million people, is the capital city and the largest in the country.

Starting in the 6th millennium BC, the fertile plains between Iraq's Tigris and Euphrates rivers, referred to as Mesopotamia, fostered the rise of early cities, civilisations, and empires including Sumer, Akkad, Babylonia, and Assyria. Known as the cradle of civilisation, Mesopotamia saw the invention of writing systems, mathematics, navigation, timekeeping, a calendar, astrology, the wheel, the sailboat, and a law code. After the Muslim conquest of Mesopotamia, Baghdad became the capital of the Abbasid Caliphate and a global cultural and intellectual hub during the Islamic Golden Age, home to institutions such as the House of Wisdom. Following Baghdad's destruction by the Mongols in 1258, Iraq came under successive empires and, from the 16th century until the 20th century, was governed within the Ottoman system as a defined region known administratively as ‘the Iraq Region’. Additionally, Iraq holds religious significance in Christianity, Judaism, Yazidism, and Mandaeism.

Banwari Trace, an Archaic (pre-ceramic) site in southwestern Trinidad, is the oldest archaeological site in the Caribbean. The site has revealed two separate periods of occupation; one between 7200 and 6100 BP (Strata I and II) and the other between 6100 BP and 5500 BP.

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.

The stamp seal (also impression seal) is a common seal die, frequently carved from stone, known at least since the 6th millennium BC (Halaf culture) and probably earlier. The dies were used to impress their picture or inscription into soft, prepared clay and sometimes in sealing wax.

The oldest stamp seals were button-shaped objects with primitive ornamental forms chiseled onto them. The stamp seals were replaced in the 4th millennium BC by cylinder seals that had to be rolled over the soft clay to leave an imprint. From the 12th century BC the previous designs were largely abandoned in favor of amphora stamps. Romans introduced their signaculum around the first century BC; Byzantine maintained the tradition in their commercial stamps.
