The art of the heroic age, then, as represented in Homer, connects itself, on the one side, with those fabulous jewels so prominent in mythological story, and entwined sometimes so oddly in its representation of human fortunes--the necklace of Eriphyle, the necklace of Helen, which Menelaus, it was said, offered at Delphi to Athene Pronoea, on the eve of his expedition against Troy--mythical objects, indeed, but which yet bear witness even thus early to the aesthetic susceptibility of the Greek temper. But, on the other hand, the art of the heroic age connects itself also with the actual early beginnings [201] of artistic production. There are touches of reality, for instance, in Homer's incidental notices of its instruments and processes; especially as regards the working of metal. He goes already to the potter's wheel for familiar, life-like illustration. In describing artistic wood-work he distinguishes various stages of work; we see clearly the instruments for turning and boring, such as the old-fashioned drill-borer, whirled round with a string; he mentions the names of two artists, the one of an actual workman, the other of a craft turned into a proper name--stray relics, accidentally preserved, of a world, as we may believe, of such wide and varied activity. The forge of Hephaestus is a true forge; the magic tripods on which he is at work are really put together by conceivable processes, known in early times. Compositions in relief similar to those which he describes were actually made out of thin metal plates cut into a convenient shape, and then beaten into the designed form by the hammer over a wooden model. These reliefs were then fastened to a differently coloured metal background or base, with nails or rivets, for there is no soldering of metals as yet. To this process the ancients gave the name of empaestik,+ such embossing being still, in our own time, a beautiful form of metal-work.
Even in the marvellous shield there are other and indirect notes of reality. In speaking of the shield of Achilles, I departed intentionally from [202] the order in which the subjects of the relief are actually introduced in the Iliad, because, just then, I wished the reader to receive the full effect of the variety and elaborateness of the composition, as a representation or picture of the whole of ancient life embraced within the circumference of a shield. But in the order in which Homer actually describes those episodes he is following the method of a very practicable form of composition, and is throughout much closer than we might at first sight suppose to the ancient armourer's proceedings. The shield is formed of five superimposed plates of different metals, each plate of smaller diameter than the one immediately below it, their flat margins showing thus as four concentric stripes or rings of metal, around a sort of boss in the centre, five metals thick, and the outermost circle or ring being the thinnest. To this arrangement the order of Homer's description corresponds. The earth and the heavenly bodies are upon this boss in the centre, like a little distant heaven hung above the broad world, and from this Homer works out, round and round, to the river Oceanus, which forms the border of the whole; the subjects answering to, or supporting each other, in a sort of heraldic order--the city at peace set over against the city besieged- -spring, summer, and autumn balancing each other--quite congruously with a certain heraldic turn common in contemporary Assyrian art, which delights in [203] this sort of conventional spacing out of its various subjects, and especially with some extant metal chargers of Assyrian work, which, like some of the earliest Greek vases with their painted plants and flowers conventionally arranged, illustrate in their humble measure such heraldic grouping.
