Looked at from in front these lions and bulls seem to be independent statues; the head, the chest, the legs stand out with as much freedom and amplitude of development as in nature; but step a little to one side, to the right or the left as the case may be, and their aspect will change. You will then see that only the fore-part of the animal is disengaged from the block of alabaster or limestone in which it is cut, the rest of the body remains imprisoned in its substance. The contours alone are indicated, in low relief, on the two sides of the ponderous slab. Thus we have half, or rather a quarter, of the statue standing out from sixteen to twenty inches in front of the slab on which the sides are shown in silhouette. It looks as if the image had made an effort to shake itself clear of the mass of stone and had only partially succeeded. We find ourselves wondering whether, if Nineveh had not perished and the development of her art had gone on without interruption, these great beasts would not have ended by conquering their liberty and winning for themselves an existence independent of the walls to which they were attached. But the nature of the material employed says no--alabaster is too soft, and the legs of the lions and bulls could not support their massive bodies without assistance.

Chardon] There are other peculiarities in these images. Looked at from in front they appear stationary, their two fore-feet being on the same plane and close together; any other arrangement would have been awkward. But if we look at them from the side they appear to be walking, in which attitude alone would all the four legs be visible and clear of each other. In most cases the bulls were not parallel to the façades they decorated, but perpendicular to them;[149] they faced the visitor as he approached the gate, and it was not until he entered the passage that he got a side view of their bodies stretching along its walls (Figs. 26 and 27). Some contrivance was sought by which their figures should appear complete from both points of view, and the following expedient was hit upon. As soon as you had entered the passage between the bulls, you could, of course, no longer see more than the fore-leg nearest you; the other was hidden by it. The latter was then repeated by the sculptor and thrown back under the body of the animal, which, in the result, had five legs.
