This is as far beyond the horizon of the fancy of the old masters as it is beyond the instrumental forces which they controlled.
"Paradise Lost," the text paraphrased from portions of Milton's epic, is an oratorio pure and simple.

It deals with the creation of the world according to the Mosaic (or as Huxley would have said, Miltonic) theory and the medium of expression is an alternation of recitatives and choruses, the latter having some dramatic life and a characteristic accompaniment.

It is wholly contemplative; there is nothing like action in it.

"The Tower of Babel" has action in the restricted sense in which it enters into Mendelssohn's oratorios, and scenic effects which would tax the utmost powers of the modern stage-machinist who might attempt to carry them out.

A mimic tower of Babel is more preposterous than a mimic temple of Dagon; yet, unless Rubinstein's stage directions are to be taken in a Pickwickian sense, we ought to listen to this music while looking at a stage-setting more colossal than any ever contemplated by dramatist before.
