If you really want to talk about beauty, and where is beauty, we first have to define it,and that is no easy task.
In the middle ages, only God was truly beautiful; with the Renaissance, that idea still persisted, but the artisan's craft was thought has a paralel to God's creation. Then, beauty was found in the forms and nature.
In the Romantism, beauty started being associated with de divine, but not God - it's Kant's Idealism at play, where one's aim is to reach the Ideas.
From there, through Schopenhauer and Nietzsxchse's aesthetic theories, art gradually became more and more about ideas (even if Nietzsche's thinking called for quite the opposite). Add in Greenberg and Adorno, and the idea of beauty is not even relevant.
It does make some sense, though, and that is why Scruton's movie annoys me so much: different ages require different images. You don't build houses, don't read, don't think or even talk the way people did a hundred years ago. To think that the culture or ideals of that time should fit ours seems to me simply absurd.
