The man from Dransdorf became quite high-spirited, and kept on shouting, "Vivat, Vivat!" Suddenly startled by the noise he made, he awoke and found himself lying on the floor of the Roman tower in the Sterngasse.
The events of the night only seemed to him like a strange dream. But when he felt in his pockets he found them stuffed with real golden coins of a strange ancient stamp.
Our friend's joy became quite uproarious. After having sent up a heartfelt thanksgiving to St. Cassius, he gave vent to his delight by shouting through the quiet streets at the top of his voice, "Vivat, Vivat!"
A watchman stood on duty by the Sternthor, when the jocund peasant passed by. He made a step forward and, reaching out his arm, he gave the merry man a rude knock with his lance. Unmindful of this rough admonition, the peasant related the event in the Roman tower to the watchman, and finished his story by inviting the stern man of duty to an early draught at the nearest inn.
Rumours of the wonderful events spread far and wide, and soon every town and village knew the tale. The small lane leading from the Minstersquare to the Sternthor was called "Vivat" lane, and bears that name to the present day.
Some years ago a heavy winter gale destroyed the old Roman tower that had so long withstood the vicissitudes of time. The people of Bonn however did not wish to obliterate the memory of this curious story, and therefore named the street running parallel with "Vivat" lane—"Cassius Graben."
