The poetry of Homer, sprung from the soil of legend, is not yet wholly detached from it, even as the figures of a bas-relief adhere to an extraneous backing of the original block. These figures are but slightly raised, and in the epic poem all is painted as past and remote. In bas- relief the figures are usually in profile, and in the epos all are characterized in the simplest manner in relief; they are not grouped together, but follow one another; so Homer's heroes advance, one by one, in succession before us. It has been remarked that the Iliad is not definitively closed, but that we are left to suppose something both to precede and to follow it. The bas-relief is equally without limit, and may be continued ad infinitum, either from before or behind, on which account the ancients preferred for it such subjects as admitted of an indefinite extension, sacrificial processions, dances, and lines of combatants, &c. Hence they also exhibited bas-reliefs on curved surfaces, such as vases, or the frieze of a rotunda, where, by the curvature, the two ends are withdrawn from our sight, and where, while we advance, one object appears as another disappears. Reading Homer is very much like such a circuit; the present object alone arresting our attention, we lose sight of that which precedes, and do not concern ourselves about what is to follow.
