[N]othing is intrinsically valuable; the value of everything is attributed to it, assigned to it, from outside, by people. - John Barth

[B]y writing an Aenead that combines an Odyssey with an Iliad, Virgil gives the impression of wanting to outdo the Homer of whom he is the self-conscious heir and to whom his Latin epic is also a homage, just as Augustan Rome is at once the cultural heir and political master of classical Greece. You want to be a great epic poet? Here are your models. Virgil follows them—programmatically but not slavishly—and because he happens to be a great epic poet, his Aenead turns out to be not a monumental Case-1 imitation of the great model, but a great epic poem. Thirteen centuries later, Dante compounds the stunt, taking as his literal and figurative guide not "unselfconscious" Homer but self-conscious (and Homer-conscious) Virgil, and not only scripts himself into the wandering hero role but orchestrates his own welcome […] into the company of the immortals—in a Limbo, moreover, where they must ineluctably remain, but from which he will proceed through Purgatory to Paradise. Talk about chutzpah! Happening to be a great poet, Dante brings the thing off.

Life teaches the storyteller his themes and subject matter; literature teaches him how to get a handle on them: what has been done already, what might be done differently, what's a story anyway, and what is to be found in the existing inventory of situations, attitudes, characters, tonalities, forms, and effects accumulated over four thousand years of written literature.

Our ability to experience life may be more or less limited by inexperience of art as well as vice versa, since each tends to increase the wattage of the great illuminator of both — namely the imagination.
