Archaeology, the scientific study of the material remains of past human life and activities

 These include human artifacts from the very earliest stone tools to the man-made objects that are buried or thrown away in the present day: everything made by human beings—from simple tools to complex machines, from the earliest houses and temples and tombs to palaces, cathedrals, and pyramids. Archaeological investigations are a principal source of knowledge of prehistoric, ancient, and extinct culture. The word comes from the Greek archaia (“ancient things”) and logos (“theory” or “science”).

The archaeologist is first a descriptive worker: he has to describe, classify, and analyze the artifacts he studies. An adequate and objective taxonomy is the basis of all archaeology, and many good archaeologists spend their lives in this activity of description and classification. But the main aim of the archaeologist is to place the material remains in historical contexts, to supplement what may be known from written sources, and, thus, to increase understanding of the past. Ultimately, then, the archaeologist is a historian: his aim is the interpretive description of the past of man.

Increasingly, many scientific techniques are used by the archaeologist, and he uses the scientific expertise of many persons who are not archaeologists in his work. The artifacts he studies must often be studied in their environmental contexts, and botanists, zoologists, soil scientists, and geologists may be brought in to identify and describe plants, animals, soils, and rocks. Radioactive carbon dating, which has revolutionized much of archaeological chronology, is a by-product of research in atomic physics. But although archaeology uses extensively the methods, techniques, and results of the physical and biological sciences, it is not a natural science; some consider it a discipline that is half science and half humanity. Perhaps it is more accurate to say that the archaeologist is first a craftsman, practicing many specialized crafts (of which excavation is the most familiar to the general public), and then a historian.

The justification for this work is the justification of all historical scholarship: to enrich the present by knowledge of the experiences and achievements of our predecessors. Because it concerns things people have made, the most direct findings of archaeology bear on the history of art and technology; but by inference it also yields information about the society, religion, and economy of the people who created the artifacts. Also, it may bring to light and interpret previously unknown written documents, providing even more certain evidence about the past.

But no one archaeologist can cover the whole range of man’s history, and there are many branches of archaeology divided by geographical areas (such as classical archaeology, the archaeology of ancient Greece and Rome; or Egyptology, the archaeology of ancient Egypt) or by periods (such as medieval archaeology and industrial archaeology). Writing began 5,000 years ago in Mesopotamia and Egypt; its beginnings were somewhat later in India and China, and later still in Europe. The aspect of archaeology that deals with the past of man before he learned to write has, since the middle of the 19th century, been referred to as prehistoric archaeology, or prehistory. In prehistory the archaeologist is paramount, for here the only sources are material and environmental.

The scope of this article is to describe briefly how archaeology came into existence as a learned discipline; how the archaeologist works in the field, museum, laboratory, and study; and how he assesses and interprets his evidence and transmutes it into history.

No doubt there have always been people who were interested in the material remains of the past, but archaeology as a discipline has its earliest origins in 15th- and 16th-century Europe, when the Renaissance Humanists looked back upon the glories of Greece and Rome. Popes, cardinals, and noblemen in Italy in the 16th century began to collect antiquities and to sponsor excavations to find more works of ancient art. These collectors were imitated by others in northern Europe who were similarly interested in antique culture. All this activity, however, was still not archaeology in the strict sense. It was more like what would be called art collecting today.

The Mediterranean and the Middle East

Archaeology proper began with an interest in the Greeks and Romans and first developed in 18th-century Italy with the excavations of the Roman cities of Pompeii and Herculaneum. Classical archaeology was established on a more scientific basis by the work of Heinrich Schliemann, who investigated the origins of Greek civilization at Troy and Mycenae in the 1870s; of M.A. Biliotti at Rhodes in this same period; of the German Archaeological Institute under Ernst Curtius at Olympia from 1875 to 1881; and of Alexander Conze at Samothrace in 1873 and 1875. Conze was the first person to include photographs in the publication of his report. Schliemann had intended to dig in Crete but did not do so, and it was left to Arthur Evans to begin work at Knossos in 1900 and to discover the Minoan civilization, ancestor of classical Greece.

Egyptian archaeology began with Napoleon’s invasion of Egypt in 1798. He brought with him scholars who set to work recording the archaeological remains of the country. The results of their work were published in the Description de l’Égypte (1808–25). As a result of discoveries made by this expedition, Jean-François Champollion was able to decipher ancient Egyptian writing for the first time in 1822. This decipherment, which enabled scholars to read the numerous writings left by the Egyptians, was the first great step forward in Egyptian archaeology. The demand for Egyptian antiquities led to organized tomb robbing by men such as Giovanni Battista Belzoni. A new era in systematic and controlled archaeological research began with the Frenchman Auguste Mariette, who also founded the Egyptian Museum at Cairo. The British archaeologist Flinders Petrie, who began work in Egypt in 1880, made great discoveries there and in Palestine during his long lifetime. Petrie developed a systematic method of excavation, the principles of which he summarized in Methods and Aims in Archaeology (1904). It was left to Howard Carter and Lord Carnarvon to make the most spectacular discovery in Egyptian archaeology, that of the tomb of Tutankhamen in 1922.

Mesopotamian archaeology also began with hectic digging into mounds in the hopes of finding treasure and works of art, but gradually these gave way in the 1840s to planned digs such as those of the Frenchman Paul-Émile Botta at Nineveh and Khorsabad, and the Englishman Austen Henry Layard at Nimrud, Kuyunjik, Nabī Yūnus, and other sites. Layard’s popular account of his excavations, Nineveh and Its Remains (1849), became the earliest and one of the most successful archaeological best-sellers. In 1846 Henry Creswicke Rawlinson became the first man to decipher the Mesopotamian cuneiform writing. Toward the end of the 19th century, systematic excavation revealed a previously unknown people, the Sumerians, who had lived in Mesopotamia before the Babylonians and Assyrians. The most impressive Sumerian excavation was that of the Royal Tombs at Ur by Leonard Woolley in 1926.

First steps to archaeology

The development of scientific archaeology in 19th-century Europe from the antiquarianism and treasure collecting of the previous three centuries was due to three things: a geological revolution, an antiquarian revolution, and the propagation of the doctrine of evolution. Geology was revolutionized in the early 19th century with the discovery and demonstration of the principles of uniformitarian stratigraphy (which determines the age of fossil remains by the stratum they occupy below the earth) by men like William Smith, Georges Cuvier, and Charles Lyell. Lyell, in his Principles of Geology (1830–33), popularized this new system and paved the way for the acceptance of the great antiquity of man. Charles Darwin regarded Lyell’s Principles as one of the two germinal works in the formation of his own ideas on evolution. Early stone tools had been identified in Europe since mid-16th century. That they were, however, older than 4004 BCE, the date of man’s origin according to biblical chronology, was not recognized until late in the 18th century, when John Frere suggested a great age for artifacts found in Suffolk, England, based on their location in certain strata. The discoveries of Jacques Boucher de Perthes in the Somme Valley in France, and of William Pengelly in the caves of South Devon in England, were used to demonstrate the antiquity of man in 1859, the same year that saw the publication of Darwin’s revolutionary Origin of Species. Approximate dates for the Paleolithic Period (Old Stone Age) of the prehistoric past were thus established, although the expression “Palaeolithic” was not used until John Lubbock coined it in his book Pre-historic Times (1865).

Half a century before this, Scandinavian archaeologists had created a revolution in antiquarian thought by postulating, on archaeological grounds, successive technological stages in man’s past. C.J. Thomsen classified the material in the Copenhagen Museum, opened to the public in 1819, on the basis of three successive ages of Stone, Bronze, and Iron. His pupil and successor, J.J.A. Worsaae, showed the correctness of this museum arrangement by observed stratigraphy in the Danish peat bogs and barrows (funerary mounds). Low lake levels in Switzerland in the mid-1850s permitted the excavation of the prehistoric Swiss lake dwellings, and here again the theory of a succession of technological stages was confirmed.

Darwin’s Origin of Species implied a long past for man, and the acceptance of the idea of human evolution in the last four decades of the 19th century created a climate of thought in which archaeology flourished and that led to great advances in the unfolding of the full story of man’s development.

In his Pre-historic Times, Lubbock expanded the three-age system of Thomsen and Worsaae to a four-age system, dividing the Stone Age into Old and New periods (Paleolithic and Neolithic). In the last quarter of the 19th century remarkable Paleolithic discoveries were made in France and Spain; these included the discovery and authentication of actual works of sculpture and cave paintings from the Upper (later) Paleolithic Period (c. 30,000–c. 10,000 BCE). When Marcellino de Sautuola discovered the cave paintings at Altamira, Spain (1875–80), most experts refused to believe they were Paleolithic; but after similar discoveries at Les Eyzies in France around 1900, they were accepted as such and were recognized as one of the most surprising and exciting archaeological discoveries. A succession of similar finds has continued in the 20th century. The most famous of these was at Lascaux, France, in 1940.

During the last quarter of the 19th century, Gen. A.H. Pitt-Rivers’ excavations of prehistoric and Roman sites at Cranborne Chase, Dorset, laid the foundations of modern scientific archaeological field technique, which was later developed and improved in England and Wales by men such as Sir Mortimer Wheeler and Sir Cyril Fox.

Developments in the 20th century and beyond

The 20th century saw the extension of archaeology outside the areas of the Near East, the Mediterranean, and Europe, to other parts of the world. In the early ’20s, excavations at Mohenjo-Daro and Harappā, in present Pakistan, revealed the existence of the prehistoric Indus civilization. In the late ’20s, excavations at An-yang in eastern China established the existence of a prehistoric Chinese culture that could be identified with the Shang dynasty of early Chinese records.

The Stone Age has been described and studied throughout the world; among the most sensational discoveries are those of L.S.B. Leakey, who found stone tools and skeletal remains of early man dating back 2,000,000 years in the Olduvai Gorge in Tanzania. Intensive work of great importance has brought to light early Neolithic sites at Jericho in Palestine; Hassuna, Iraq; Çatalhüyük, Turkey; and elsewhere in the Near East, establishing the origins of agriculture in that region.

Serious archaeological work began later in America than Europe, but as early as 1784 Thomas Jefferson had excavated mounds in Virginia and made careful stratigraphical observations. The 20th century saw a great increase in archaeological knowledge about prehistoric America: two startling advances were the discovery of the origin of domesticated crops (including maize) in Central America and of the Olmec civilization of Mexico (1000–300 BCE)—the oldest of the New World civilizations and probably the parent of all the others.

The enormous growth of archaeological work has meant the establishment of archaeology as an academic discipline; few important universities anywhere in the world are now without professors and departments of archaeology. There are now a very large number of scholarly journals in the field, as well as a considerable body of popularized books and journals that attempt to bridge the gap between professional and layman.
