It is in this valley, probably one of the most romantic in the world, that we find the legendary lore of the river packed in such richness that every foot of its banks has its place in tradition. But that is not to say that this portion of the Rhine is wanting in natural beauty. Here are situated some of its sunniest vineyards, its most wildly romantic heights, and its most picturesque ruins. This part of its course may be said to end at the Siebengebirge, or 'Seven Mountains,' where the river again widens and the banks become more bare and uninteresting. Passing Bonn and Cologne, the bareness of the landscape is remarkable after the variety of that from which we have just emerged, and henceforward the river takes on what may be called a 'Dutch' appearance. After entering Holland it divides into two branches, the Waal flowing to the west and uniting with the Maas. The smaller branch to the right is still called the Rhine, and throws off another branch, the Yssel, which flows into the Zuider Zee. Once more the river bifurcates into insignificant streams, one of which is called the Kromme Rijn, and beyond Utrecht, and under the name of the Oude Rijn, or Old Rhine, it becomes so stagnant that it requires the aid of a canal to drain it into the sea. Anciently the Rhine at this part of its course was an abounding stream, but by the ninth century the sands at Katwijk had silted it up, and it was only in the beginning of last century that its way to the sea was made clear. The Sunken City More than six centuries ago Stavoren was one of the chief commercial towns of Holland. Its merchants traded with all parts of the world, and brought back their ships laden with rich cargoes, and the city became ever more prosperous. The majority of the people of Stavoren were well-to-do, and as their wealth increased they became luxurious and dissipated, each striving to outdo the others in the magnificence of their homes and the extravagance of their hospitality. Many of their houses, we are told, were like the palaces of princes, built of white marble, furnished with the greatest sumptuousness, and decorated with the costliest hangings and the rarest statuary. But, says the legend, of all the Stavoren folk there was none wealthier than young Richberta. This maiden owned a fleet of the finest merchant-vessels of the city, and loved to ornament her palace with the rich merchandise which these brought from foreign ports. With all her jewels and gold and silver treasures, however, Richberta was not happy. She gave gorgeous banquets to the other merchant-princes of the place, each more magnificent than the last, not because she received any pleasure from thus dispensing hospitality, but because she desired to create envy and astonishment in the breasts of her guests.
