There are some great works here; such a display of skill, detail and classical themes that I admire and enjoy: I can tell an Argus from an Io, or a Hydra from a hyrax from many hundreds of yards away...these artists have the same knack.
But the writer methinks doth protest too much: it is kinda sad that the shared (well, among educated White People) Classical Heritage of Greek Mythologies are but a faint echo culturally of what they had been for the Western World, Lo, these past two and half Millennia.
But...things fall apart. It's been a rough and tumble thrill ride the last 150 years or so: Art, whether profane, profound or popular...has mirrored it.
"I know now absolutely that nearly all the works by most of the famous Modernists are truly awful on all fronts..." I can imagine how a lover of these types of works might feel that way...it sure can feel like the Emperors New Clothes when being confronted by many forms of Art.
Similar to the writer for the American Record Guide, who seems to feel that every piece of music written or performed since Gustav Mahler put down his quill is akin to listening to lemurs flagellating each other with thorny branches. Yet from my personal experience...the 'value' of artistic works are due as much to the hand of the creator as to the effect they have upon the viewer.
