In academic, historical, and archaeological circles, A. Dates are determined by a variety of processes, including chemical analyses (as in radiocarbon dating and thermoluminescence), data correlation (as in dendrochronology), and a variety of other tests. Acheulean - A stone tool industry, in use from about 1.6 million years ago until 125,000 years ago. - "Abbreviation for the term Anno Domini Nostri Jesu Christi (or simply Anno Domini) which means ""in the year of our Lord Jesus Christ."" Years are counted from the traditionally recognized year of the birth of Jesus. E.)." Absolute Dating - Collective term for techniques that assign specific dates or date ranges, in calendar years, to artifacts and other archaeological finds.Different researchers have applied a variety of absolute dating methods directly to petroglyphs or to sediments covering them, including AMS (accelerator mass spectrometry) radiocarbon, cation ratio, amino acid racemization, OSL (optically stimulated luminescence), lichenometry, micro-erosion and micro-stratification analysis of patina. These techniques have yielded mixed results in terms of reliability and feasibility, but, in any case, none has been applied to date in Saudi Arabia.

Acropolis - The "high point" or citadel of an ancient Greek city, like the Acropolis in Athens.

Aerial Photography - The various techniques of taking photographs of natural or cultural features from the air, using balloons, airplanes, satellites, and other sources, in order to study the features in their entirety from a top-down (bird's eye) view.

Aerial Reconnaissance - The technique of searching for sites and features, both cultural and natural, from the air, often using aerial photography or the human eye.

These techniques both place assemblages of artefacts into relative order.

Petrie used sequence dating to work back from the earliest historical phases of Egypt into pre-dynastic Neolithic times, using groups of contemporary artefacts deposited together at a single time in graves.Given the current status of direct chronometric dating methods for Arabian petroglyphs, it is rare that the precise age of a rock art panel can be determined.However, all is not lost, and it is possible to establish a temporal sequence that can be quite edifying.It is increasingly difficult for prehistorians working in the twenty-first century to conceptualise the problems experienced by their predecessors, and approaches to interpretation before the 1960s are consistently criticised.
