4. Passing from architectural to moveable objects, I observe that Dr. Schliemann found both knives and keys of iron in Mycenæ, but that from their form he assigns them to a later and strictly historic period. Old Mycenæ, therefore, in accordance with Hissarlik, has afforded us, up to the present time, no remains of this metal. In the Poems it is freely mentioned, but as a rare and valuable substance, used where great hardness was required, and for objects comparatively small and portable; except, indeed, in the case of the Gates of Tartaros (_Il._ VIII 15), where the Poet could dispose of as much material as he pleased. The aggregate quantity, then, was small; and the instruments were likely to be carried away on the abandonment or destruction of a city. Its absence may therefore be accounted for, in part by its value, but also, and more especially, because it so readily corrodes.[3] Therefore, although we cannot here establish a positive correspondence, neither have we any occasion to admit a discrepancy. 5. Neither need we, I think, suppose any variance between the chariot, as our author found it on the second tombstone of the Acropolis (p. 84), and the Homeric picture. True, he finds a wheel of four spokes, and the Olympian car of Hera had eight (_Il._ V. 723); but this diversity of structure is probably introduced, like the diversity of material, by way of divine distinction, and to show the superior elaboration and strength of the vehicle.[4] 6. We have at Mycenæ the _Agora_, or place of Assembly, in full agreement with the Poems on the two points, first of its circular form (pp. 338, 339), and secondly of the smoothed horizontal slabs, bounding the circle, on which the Elders sate. I do not dilate upon these, as they are fully noticed in the text: but I shall return to the subject, in connection with the situation chosen for the tombs, and the inferences which are to be drawn from this important circumstance. I will now hazard, before proceeding further with my list, one or two general remarks on the works of art and ornament, referring again to the reports of Mr. Newton and Mr. Gardner, as the most trustworthy comment on the text of our author concerning them.
