The Shoes That Were Danced to Pieces
Jacob and Wilhelm Grimm
Once upon a time there was a king who had twelve daughters, each one more beautiful than the others. They slept together in one room, where their beds stood next to each other. At night when they were lying there, the king closed their door and barred it. However, when he opened it the next morning he saw that their shoes had been danced to pieces. No one could determine how it had happened. Then the king proclaimed that whoever could discover where they went dancing each night could chose one of them for his wife and become king after his death. However, anyone who attempted this, but failed to make the discovery after three days and nights, would forfeit his life.
有个国王，他有十二个女儿，个个长得如花似玉。她们都在同一个房间睡觉，十二张床并排放着，晚上上床睡觉后，房门就被关起来锁上了。有一个时期，每天早上起来后，国王发现她们的鞋子都磨破了，就像她们跳了一整夜舞似的。到底发生了甚么事，她们到哪儿去过了，没有人知道。於是，国王通告全国：如果有人能解开这个秘密，找出这些公主整夜在哪儿跳舞，他就可以娶一个他最喜欢的公主作妻子，还可以继承王位。但要是这人在三天以后没查清结果，他就得被处死。
A prince soon presented himself, offering to undertake the venture. He was well received, and that evening was taken to a room adjacent to the bedroom. A bed was made for him there, and he was told to watch where they went and danced. So they would not be able to do anything in secret, or go out to some other place, the door to their room was left open. However, the prince's eyes felt as heavy as lead, and he fell asleep. When he awoke the next morning, the twelve had been dancing, for their shoes all had holes in their soles. The same thing happened the second and the third evenings, and his head was chopped off without mercy. Many others came to try this risky venture, but they too all lost their lives.
不久从邻国来了一位王子，受到了热情的接待。晚上他被带到了一个房间里，这房间正在公主们卧室的隔壁。为了能听到看到可能发生的一切，他坐下后将房门敞开，一刻也不停地注视着。可不久这位王子就睡着了，第二天早上醒来后，可以看出，公主们还是跳了一整夜的舞，因为她们的鞋底上都有磨破的洞眼。接着两个晚上都发生了相同的情况，王子没能解开这个谜。国王下令将他的头砍了下来。继他之后，又有几个人来试过，但他们的命运和这位王子一样，都没有找出结果而丢了性命。
Now it happened that a poor soldier, who was wounded and could no longer serve in the army, was making his way to the city where the king lived. An old woman met him and asked him where he was going. "I'm not exactly sure myself," he said, then jokingly added, "But I would like to discover where the princesses are dancing their shoes to pieces, and then become king."
恰好有一个老兵经过这个国王的领地，他在作战中受了伤，不能再参加战斗了。一天，他在穿越树林时，遇到了一个老婆婆，老婆婆问他要到哪里去，这位老兵回答说：“我也不知道我去哪儿，该干甚么去。”接着又自我嘲弄地说：“也许我该去探听那些公主是在哪儿跳舞才对，这样的话，将来还可以当国王呢。”老太婆一听，说道：“对，对!这不是甚么难事，只要留心不喝公主给你的酒之类的东西，并且在她们要离去时，你假装睡熟了就成。”
"That is not so difficult," said the old woman. "Do not drink the wine that they will bring you in the evening." Then she gave him a cloak and said, "When you put this on you will become invisible, and you can follow the twelve."
临别，她送给他一件披风，说道：“只要你把这件披风披在身上，她们就看不见你的踪影了。然后，你就可以跟着公主到她们去的任何地方。”老兵听了这些忠告后，决定去试一试自己的运气。
Having receiving this good advice, the soldier became serious, took heart, went to the king, and announced himself as a suitor. He, like the others, was well received, and was given royal clothes to wear. That evening at bedtime he was escorted to the anteroom. Just as he was going to bed, the oldest princess brought him a goblet of wine. However, he had tied a sponge beneath his chin and let the wine run into it, drinking not a single drop himself. He lay down, and after a little while began to snore as if he were in the deepest sleep. The twelve princesses heard him and laughed. The oldest one said, "He could have spared his life as well!"
他来到国王面前，说他愿意接受这项冒险的任务。和其他应试的人一样，他也受到了热情的款待，国王还下令把漂亮的`王室礼服给他穿上。到了晚上，他被带到了外室。进房后，他刚准备躺下，国王的大公主就给他端来了一杯葡萄酒，但这位士兵悄悄地把酒全倒掉了，一滴也没有喝下。然后躺在床上，不久就大声地打起鼾来，好像睡得很沉似的。十二个公主听到他的鼾声，都开心地大笑起来，大公主说：“这家伙本来还可以干一些更聪明一点的事，不必到这儿来送死的。”
Then they got up, opened their wardrobes, chests, and closets, took out their best clothes, and made themselves beautiful in front of their mirrors, all the time jumping about in anticipation of the dance. Only the youngest one said, "I'm not sure. You are all very happy, but I'm afraid that something bad is going to happen!"
说完，她们都起床打开各自的抽屉和箱子，拿出了漂亮的衣服，对着镜子打扮起来。这时，最小的公主说道：“我感到有些不对劲，你们这么兴奋，可我觉得非常不安，我想一定有不幸的事情将降临到我们头上。”
