Later writers occasionally add information, which is of value only in so far as it derives from a trustworthy source. The most important of these authors are the Augustan geographer Strabo, Pausanias, the compiler of an antiquarian guide to Greece in the second century AD, and the essayist and biographer Plutarch (roughly AD 50–120), whose lives of Lykourgos, Solon and Themistokes reflect a late and imaginative tradition. Diodorus’ Historical Library (written in Rome before about 30 BC) preserves in its history of early Greece a précis of parts of the general history of the fourth century writer Ephoros, a rhetorical work largely derivative on Herodotus for this period.
The earliest inscriptions of more than a few words are in verse, but writing was quickly and widely used to record almost anything; for the period from the beginning of Greek writing down to the Persian Wars well over 5000 inscriptions are known, most of them of course very short. They are found in those types of material that can survive, bronze, lead, and especially pottery and stone; we should not forget the many documents that once existed on wood, parchment, wax tablets and papyrus. Some of the more important documents will be used as evidence later; these are mostly religious or commemorative (tombstones or dedications at shrines), or political (laws and treaties). The earliest surviving law is late seventh century, but the practice of putting up laws in public on stone or wood was common by the period of the Persian Wars.
The Mediterranean has been a hunting ground for European archaeologists for a century. The most useless site is the one which is still inhabited: Thebes, Chalcis, Greek Marseilles and early Syracuse are virtually unknown. The Athenian agora is only partly excavated because its true extent was miscalculated when the expropriations of owners by the government were carried out; more successful was the physical transplantation of the village of Delphi to a pleasanter and archaeologically barren site, against the wishes of the inhabitants and at French government expense (the French had won the right to excavate by removing the duty on Greek currants). Many sites in Asia Minor especially are disappointing because there was extensive rebuilding there in Hellenistic and Roman times: Delos and Cyrene are other examples. Particularly fruitful are sites that have been abandoned or sparsely occupied, with or without violent destruction (for instance Smyrna, the shrine of Perachora on the Isthmus of Corinth, Paestum); but the sacking and rebuilding of a city can also preserve – the survival of late archaic art is due largely to the sack of Athens by the Persians in 480 and the Periklean rebuilding, which caused the temple sculptures of Peisistratid Athens to be buried in the new foundations soon after they were carved. Excavations have been conducted at most of the obvious sites, the centres of archaic culture – Sparta, Aegina, Olympia, Athens, Samos, the Argolid, the Sicilian colonies; some less obvious sites turn out to be particularly rewarding because of their position – for instance Al Mina in north Syria or Naucratis in Egypt. Fringe areas such as the Scythian royal tombs or Celtic Gaul often provide important evidence because of their different burial customs: the cemeteries and other sites of Etruria have yielded so much Greek pottery that the eighteenth century thought Greek vases were Etruscan (Josiah Wedgwood called his pottery factory Etruria); there are few Greek museums whose collections can rival those of the great Italian Etruscan museums.
In relating different sites to each other and archaeological evidence in general to other types of evidence, the primary need is for an adequate chronological framework. For archaic Greece this is provided by pottery. In contrast to other artefacts pottery is of comparatively little value even when decorated, breakable, and when broken both useless and indestructible; in early Greece, painted pottery was a major art form whose styles varied from city to city and changed continually, so that it is comparatively easy to work out a relative chronology within each style. The styles of many areas were not widely distributed; Laconian pottery for instance is virtually confined to Sparta and its colony Tarentum; the various east Greek potteries are often difficult to distinguish, and their places of origin and chronological relationships are not yet fully determined. Such local styles are of limited interest in recording the presence of Greeks from a particular area in a particular place. Two cities, however, successively captured a wider market for their pottery: it is these styles, found all over the Mediterranean, which provide a relative chronology for archaeological sites in general, which can then be tied to absolute dates through known fixed points. Thus the dates of foundation of the Sicilian colonies given by Thucydides fix the beginnings of the early proto-Corinthian style; the sack of Athens in 480 offers another fixed point at the end of the archaic age, and there are a number of such fixes in between.
The pottery of Corinth was the first to achieve widespread circulation, helped of course by the city’s position as the starting point of the route to the west. Contact with the near east and the import of textiles and metalwork brought various decorative motifs to Greek art, and especially an interest in the realistic portrayal of animal and vegetable life: this orientalizing style appears in Corinthian pottery first about 725, when the late Geometric style gives way to early proto-Corinthian. The invention of the Black Figure technique of painting came within a generation (middle proto-Corinthian, c. 700–650); in this the figures are painted in black silhouette and details are then engraved on the figures after firing.
Corinthian pottery was the only ware widely exported for about a century; in the sixth century it was superseded by Athenian. Attic Black Figure began under the influence of Corinth (610–550), but quickly won pre-eminence, and in its mature phase (c. 570–25) reached an artistic perfection which has made it famous ever since. By about 530 a new technique of painting had been invented in Athens, the Red Figure technique, in which it is the background which is painted black, and the details of the figures are drawn in by brush. So individual are the styles of the different Black Figure and Red Figure artists that the same methods can be applied to distinguishing their hands as have been applied to Renaissance and later painters: the work of Sir John Beazley has resulted in the more or less certain identification of the work of over a thousand artists, and their classification both chronologically and into schools. Quite apart from our knowledge of painted pottery as an art form, this has given a chronological precision unknown in any other area of archaeology.
In more general terms the contribution of archaeology to the study of early Greek history is enormously greater than for most periods of history. It has explained many aspects of the origins and growth of Greek culture, its interdependence and local variations, the external influences on it and the means by which they arrived. It has illuminated the patterns of trade and colonization, and the major advances in warfare which lie at the basis of Greek geographical expansion and the diffusion of political power to a widening circle. Archaeology of course has obvious limitations, in that it can only offer partial insight into the less material aspects of life – religion, politics, culture and ideas; but it is more important to point out the areas where it still has more to contribute. Archaeologists have tended to concentrate on change rather than on continuity, and to direct their attention to certain areas of culture whose relative importance is not obvious. Thus we still know more about town centres than about towns, and about towns than about the countryside, or about weapons than about agricultural implements, and much more about the dead than the living. Despite the fact that Greek archaeology has stood as a model for other periods for so long, much remains to be done; and what is done will illuminate especially those areas about which literary and epigraphic sources are comparatively silent. The light thrown on the Dark Age in the last generation is an outstanding example of what can be achieved; and recent developments in survey archaeology have begun to illuminate the history of the countryside.
