We undertake this long detour in order that we may arrive in Greece instructed by all that we have learnt on the way, and prepared to understand and to judge; but during the whole voyage our eyes will be turned towards Greece, as those of the traveller towards his long-desired goal. Our route will conduct us from the shores of the Nile to those of the Euphrates and Tigris, over the plains of Medea and Persia and Asia Minor to the shores of Phœnicia, to Cyprus and Rhodes. But beyond the obelisks and pyramids of Egypt, beyond the towers of Chaldæa and the domes of Nineveh, the lofty colonnades of Persepolis, the fortresses and rock-cut tombs of Phrygia and Lycia, beyond the huge ramparts of the cities of Syria, we shall never cease to perceive on the horizon the sacred rock of the Athenian acropolis; we shall see it before us, as our history of the past advances, lifting into the azure sky the elegant severity of its marble porticoes, the majesty of those pediments where live and breathe the gods of Homer and Phidias.
When we have crossed the threshold of the Propylæa, and have visited the Parthenon, the Erecthæum, and the temple of the Wingless Victory; when we have seen all Greece become covered with monuments of architecture and sculpture, which, without rivalling those of Athens in purity of line or finesse of execution, bear the impress of the same style and the same taste; when we have seen Praxiteles and Scopas succeed to Phidias and Polycletus, will it not cost us a struggle to quit the scene of so many wonders and conclude our voyage? If we leave the Athens of Cimon, of Pericles, and Lycurgus, for the pompous capitals of the heirs of Alexander; if we cross the sea to visit Veii and Clusium, to describe the Etruscan cemeteries with the fantastic magnificence of their decoration; if at last we find ourselves in imperial Rome, among its basilicas, its baths, its amphitheatres, and all the sumptuous evidence of its luxury, we shall now and again turn our eyes with regret to what we have left behind; and, although we shall endeavour to comprehend and to judge with the liberality and largeness of taste and sympathy which is the honour of contemporary criticism, we shall sometimes sigh for that ideal of pure and sovereign beauty which we adored in Greece; and shall feel, now and again, the nostalgia of the exile.
IV.
In this sketch of our plan, we have reserved no place for the art which is called prehistoric, the art of the caverns and the lake dwellings. This omission may surprise some of our readers, and we therefore beg to submit for their consideration the reasons which, after grave reflection, have induced us to refrain from retracing the first steps of human industry, from describing the first manifestations of the plastic instinct of mankind.
We are actuated by neither indifference nor disdain. We fully appreciate the importance of such researches, and of the results to which they have led. No sooner had it entered into the mind of man to look for and collect the humble remains upon which so many centuries had looked with indifference, than they were found almost everywhere, thickly dispersed near the surface of the earth, heaped among the bones of deer in the grottoes for which men and animals had once contended, buried in peat marshes and sandy shores, sometimes even sprinkled upon the surface of the fields and country roads. Pieces of flint, bone, or horn, fashioned into instruments of the chase, into fishhooks, and domestic utensils; shells, perforated teeth, amber balls which were once strung upon necklaces and bracelets; fragments of rough tissue and of skin garments; seeds and carbonized fruits; earthen vessels made by hand and dried in the sun or simply in the open air. In some of the cave dwellings, bones and pieces of horn have been found upon which the figures of animals are carved with a truth and spirit which allow their species to be at once and certainly recognized.
But none of these remains bear the slightest trace of a system of signs for the transmission of ideas or recollections; there is nothing which suggests writing; and, more significant still, there is a complete absence of metal. All this is evidence that the remains in question belong to a very remote antiquity, to a period much nearer the primitive barbarism than to the civilization of Egypt and Chaldæa, to say nothing of that of Greece and Rome. The comparative method, which has done so much for natural science, has also taken these remains in hand, has attempted to classify them and to gain from them some notion of the life led by the early human families which manufactured them. These arms, tools, and instruments which have been recovered from the soil of the old and cultivated nations of Europe, have been carefully compared with similar objects still in use by the savage races which people the far corners of the world. These comparisons have enabled us to decide the former use of each of the objects discovered. By collating the observations of the various travellers who have visited the savage races in question, we have been enabled to form for ourselves a probably truthful picture, so far as it goes, of the life and social habits of those primitive Europeans who made use of similar tools and weapons. And that is not all. The general character of those early periods being established, further examination brought to light the local differences which prevailed then as now. Thus the proneness to plastic imitation seems to have been peculiar to a few tribes—although traces of this taste are found elsewhere, it is nowhere so marked as among those primitive cave-dwellers of Perigord whom Christy and Edouard Lartet have so patiently studied.
By dint of careful classification and comparison, we have been enabled to follow the march of progress through those countless centuries whose number will never be known to us, whose total would, perhaps, oppress our imaginations if we knew it; we have been enabled to discover the slow steps by which mankind raised itself from the earliest, almost shapeless, flint axe, found with the bones of the mammoth in the quaternary alluvial deposits, to the rich and varied equipment of "lacustrian civilization," as it has sometimes been called. In this unlimited field, of which one side at least must ever be lost in unfathomable obscurity, the main divisions have been traced; the stone age has been defined and divided into the palæolithic and neolithic epochs; the age of bronze followed, and then came the iron age. With the appearance of the former metal the tribes of northern and central Europe established a connection with the civilized races which surrounded the Mediterranean, and with iron we are in the full classic period.
