A great full moon was rising behind the castle at Heidelberg, and the neckar was a streak of light.
"The Pastor's Wife"
Elizabeth von Arnim
My old castle-building propensities came back upon me in an instant, and I pictured myself, with Lady Jane as my companion, wandering among the beautiful scenery of the neckar, beneath the lofty ruins of Heidelberg, or skimming the placid surface of the Rhine, while, "mellowed by distance," came the rich chorus of a student's melody, filling the air with its flood of song.
"The Confessions of Harry Lorrequer, Complete"
Charles James Lever (1806-1872)
In the deep gorges the black water of the Nagold foams and tumbles among the hollow rocks, or glides smoothly over the long and shallow races by which the jointed timber rafts are shot down to the neckar, and thence to the Rhine and the ocean, many hundreds of miles away.
