First, art historical analysis of classical art, which throughout the
middle decades of this century fostered a strange and crippling attitude
toward Roman copies of Greek originals -- such that art historians trained
themselves and their students to "look through" the Roman versions until
they could see the Greek originals, in a frankly mystical mode. This is
in part driven, I think (here's my second item) by Modernist, and specifically
anti-representational, developments in the twentieth- century art world,
as classical art historians (along a track also followed by scholars of
classical literature) experience a collective drive to present classical
art as the representational salvation of western art, in response to the
muddles and trends created by the fertile new non-representational artforms.
The problem of the Roman copies then becomes paramount: what to do with
the fact that the perfection of the Greek representation of the human body
can only be
perceived via the "stiff mimicry" of the Romans? The idolatry of representational
perfection runs into material trouble -- or so they seem to have thought.
Third: how might all this have intersected with/influenced the aesthetics
of mid-century New Critical readings of Latin literature, specifically
Virgil? Here the newly intensified idolatry of the pastoral is closely
linked to both external politics (mentioned in your description) and with
contemporary developments in poetry (my knowledge extends only to American
and English poetry, I'm afraid; I'm sure there's plenty more to be said
about continental writing). But -- as with Roman sculpture and painting
-- there are problems with setting Virgil up as a classical ideal, many
of them involved with his identity as a Roman copier, and this is especially
problematic for the Theocritean Eclogues. So while the whole High
Modernist crew in France in the teens through the 30s is thinking in very
neoteric terms, Pound (to take one example) starts to write popular diatribes
throughout the late 40s, 50s and 60s against Virgil and Latin poetry in
general, and his quotations of Ovid, so prominent in the early Cantos,
diminish in the late ones. Classicists' attempts to frame the Eclogues
in utopian terms, I think, are in some way responding to this kind of thing
as well.
