Another remarkable feature of Visby is the city wall. It completely encircles the city, and is the only example in Scandinavia that has lasted to our time. It dates from early in the thirteenth century. It was gradually made stronger by adding to its height and its thickness, and also by building thirty-six towers, two to guard each gate. Many of these have a name. The powder-tower was named Silfverhättan (Silver-cap). Its shining roof is now replaced by dull tiles. One is used as a prison, and is named “Cæsar.” Another is called Jungfru Tornet (the Maiden’s Tower). It is said that a young girl betrayed this city to King Waldemar. As a punishment she was built into the wall of the tower. Near a gate on the south side of the city can be seen a cross put up to the memory of the 1,800 men of Visby who were killed when that King took the city. On it is an inscription in Latin, still legible--“In the year 1361, the Tuesday after St. James’s day, the Gothlanders fell before the gates of Visby by the hands of the Danes. They lie buried here. Pray for them.” CHAPTER XIII FAIRY-TALES I wonder how children would do without fairy-tales. Every country and every age has these, and devours them eagerly, old as they are. Perhaps it would be interesting to inquire how they arose. It is said that a Queen saw her children looking very sad, although they had everything that she could think of for their happiness. The truth was they did not know what they wanted. She said, “If only I were a child again, I would know what is the secret of a child’s happiness.” While she was thinking a bird flew into her lap, but only for a moment. As soon as it had gone, she saw a golden egg. “Perhaps,” she thought, “this egg will contain what will give my children contentment, and remove their sadness.” She broke the egg, and out came the wonderful bird, Imagination, the Popular Tale. Now the children were happy and bright. For the tale took them far away, but brought them home again as soon as they desired. So it came about that not only children, but those who are older in years, found a peculiar joy and happiness in reading the story, provided they come in the spirit of the child. Here is one well known to Swedish children: THE CRAFTY BOY AND THE STUPID GIANT
