We propose an excitonic mechanism for high temperature superconductivity in YBa2Cu3O7. We feel that in this material, nature has provided a very elegant system, closely simulated by the model proposed by Allender, Bray and Bardeen1 using Ginzburg's ideas.2 In this system the excitonic layer and the conduction electron layers are indeed atomic planes making contacts on atomic level, an ideal version of the situation envisaged by Allender et al. Further, since these layers are physically separated, the question of screening of charges is avoided.
