On the Heights by Berthold Auerbach

Walpurga found herself in the interior quadrangle of the palace. She was quite giddy, with looking at the many doors, the great windows, the broad staircases and the coats of arms, emblazoned with figures of wild men and beasts. All seemed wondrous strange under the glare of the gas lamps, the strong lights, here and there, contrasting with the deep, mysterious shadows. Walpurga stared about her with a dreamy vacant gaze. Giving way to memories of olden legends, she thought of the young mother whom the genii of the mountain had carried off to a subterranean cavern, where they detained her by means of a magic charm, while she nursed a new-born babe.

But she was recalled to herself at last. From the palace-guard, where the muskets were stacked in two long rows and the sentry was marching to and fro, she heard one of the songs of her home.
