"Under such circumstances, the firmament, of course, could not be dispensed with. So we had wandering suns and moons, and jingling stars in motion. Even the animal kingdom was summoned to activity. Cuckoos, nightingales, and every species of bird, singing, or rather chirping, glorified the festival of Christmas, and announced to the assembled congregation the birth of the Redeemer. Eagles flapped their wings, or flew towards an artificial sun. The climax, however, of all these rarities, was the _fox-tail_. It was intended to frighten away from the organ all such inquisitive persons as had no business near it. Thus, when they pulled out this draw-stop, suddenly a large fox-tail flew into their faces! It is clear that by such absurd practices, curiosity was much rather excited than stopped, and that all this host of moving figures, and their ridiculous jingling, disturbed meditation, excited the curiosity of the congregation, and thus disparaged the sublimity of divine service." Of course all this nonsense in due time brought its own cure with it. The money expended was diverted towards its worthy and legitimate object, and to-day, in Europe, but few such relics of the past can be found, and those generally in out-of-the-way places. I have myself seen but one organ containing any of these absurdities. That was in a small town of Camin, on the Baltic sea-coast of North Prussia, and I was informed by the old organist (as Seidel says) that these things were _reserved for Christmas and Easter_! While the power, compass, and variety of organ tone, as well as the mechanism of the instrument, made steady progress throughout the fifteenth and sixteenth centuries, the science of harmony in the largest sense kept even pace with it, and, perhaps, received even a greater relative development. Meantime, the orchestral instruments of the day had received a fair share of improvement. The harpsichord had been invented, and sufficiently perfected to be worthy of the powers of such a master as Sebastian Bach. With the appearance of this great man the art of counterpoint reached its culmination, never surpassed, if even equalled in isolated instances, by any subsequent writer. His organ compositions cover every resource, both in design and execution, possible to the organ of his day; and yet, I do not think it too much to say that, had Bach never written a single organ piece, his claims for recognition as a great composer would remain substantially the same. His greatest works are to be found among his vocal and orchestral writings. Let us examine for a moment the reason for this, and of the influence of the "king of instruments" upon musical composition at this time.
