Archaeology
Archaeology |ɑːkɪˈɒlədʒɪ| (Greek: αρχαίος "ancient" + λόγος "word / speech / discourse"; alternatives: archeology, archæology) is the scientific study of past human cultures by means of the recovery, documentation and analysis of material remains and environmental data. The broad scientific goals of archaeology are to document and explain the development of human culture, globally and diachronically, from its origins to the recent past. Methods include invasive practices such as excavation and non-invasive procedures such as the use of geophysics.
A practitioner of the discipline of archaeology is generally known as an "archaeologist". Archaeologists tend to develop one or more specialisations—with respect to technique, region and/or period studied—in the course of their training and career.
Development of the study
The Renaissance saw growing interest in collecting objects for aesthetic reasons, which was a precursor to museums and the study of material culture. One such collection was donated to the University of Oxford and a museum to house the collection opened in 1683 (the institution would later move to larger permises and become the Ashmolean Museum). The Grand Tour – a journey round Europe for those of wealth and independence – saw people become more interested in historic sites.[1] However, it was not until the 19th century that archaeology emerged as a discipline with methods of recording and preservation. The subject was influenced by principles of stratigraphy, developed in the 17th century by the relatively new study of geology.[2] Archaeology helped shed light on the early history of humanity. The idea that the world was a few thousand years old, based on creationism, was challenged by evidence that man had existed long far longer. As a result, the term "prehistory" was coined.[3]
Dating methods
Dating archaeological contexts and finds is essential to providing a chronology of a site. Methods for dating can be divided into two groups: relative and absolute. Relative dating is the process of establishing a chronology and placing events or artefacts within this framework. Two common methods are stratigraphy and typology. Typological sequences can be constructed when there is a development in design of an object.[4] Mobile phones, for instance, started off as large and bulky devices. Over time they became smaller, and a acquired new features; aerials fell out of use, cameras became common, and the number of buttons decreased as touch screens became more common. Therefore it is possible to take an example of a phone and place it within a certain stage of development without the need to know the precise date the model was manufactured. Absolute dating seeks to apply date ranges to a particular event.
