We enter. It needs some effort of faith to believe that this roof, so cunningly put together of stones which have all but reached the secret of the true cupola, was once covered with brazen plates--that we are, in fact, in what once was one of the brazen chambers of which the poets tell us. From one point of view we may be glad that they are gone, as otherwise we could not so well have studied this wonderful construction. It is as marked a moment in a course of constructive study when we stand in the treasury of Mykênê as when we stand in the peristyle of Spalato. Each marks a great step in the history of art. In one we see how nearly men could come to the arched construction without actually reaching it. In the other we see the perfect construction applied for the first time to its highest artistic use. But Spalato is the direct parent of all that came after it. Mykênê is the parent of nothing. It surely points to some great revolution, some overthrow of the more civilized people by the less civilized, that the art of primæval Greece should have stopped where it did. In all these early buildings we find the arched construction only not brought to perfection. In the artistic architecture of historical Greece the arch, or any approach to it, as an artistic feature, was utterly unknown. At the outside, it is barely used here and there, in works which did not claim to be works of art, where the merest constructive necessity called for it. To any one who is familiar with Irish remains the treasury of Mykênê cannot fail to suggest New Grange. The essential construction of the two works is the same. But here again the ever needful warning comes in. All that the undoubted likeness really proves is that the same stage of constructive skill was reached, in times perhaps far removed from one another, in Ireland and in Peloponnêsos. It does not prove, it does not even suggest, any nearer connexion than this. Otherwise, no field could be more tempting for a mystic ethnologist. Were there not Danaoi in Argolis? And was there not in Ireland also a people with a name very like Danaoi, but which we will not attempt to spell without an Irish library at hand?
