Does Grecian Work How Does Keats Differ From Shelley In The Way He Approaches The Myth Or Permanence In The Ode To A Grecian Urn

How does Keats differ from Shelley in the way he approaches the myth or permanence in the ode to a grecian urn - does grecian work

God, my wife was an English major, and his thesis had something to do with the Greek urn of Keats and treatment of fairies.

Anyway, my mind, education:
Keats immortalized valid and myth in his Ode on a Grecian Urn, and reaffirms the importance of these myths.
Meanwhile a Gothic novelist Shelley (Frankenstein), and seemed more about the horror and evil of the new technologies.

While Keats with curiosity and longing for the past while Shelley was screaming in horror at what he saw in the future.
