牧人和小牛犊
The Herdsman and the Lost Bull-Calf
牧人在树林中放牛，不小心丢失了一只小牛犊。他在树林里四处寻找，却毫无收获。于是，他就对赫耳墨斯、潘和森林守护神发誓，只要可以找到偷小牛犊的贼，他愿意用一头山羊献祭。没过多久，他走上小山丘，忽然看到山下有只狮子正在美美地享用他的小牛犊。他顿时惊慌失措，高举双手，仰望着天空，大声祈求说：“我刚才发誓，如果我能捉到偷小牛犊的贼，我愿意把一头山羊献给守护神。现在，我发誓，只要能逃脱狮子的魔爪，我愿意献上一头大牛。”
要认真对待自己的誓言，你的誓言才可能会实现。
A Herdsman tending his flock in a forest lost a Bull-Calf from the fold. After a long and fruitless search，he made a vow that，if he could only discover the thief who had stolen the Calf，he would offer a lamb in sacrifice to Hermes，Pan，and the Guardian Deities of the forest. Not long afterwards，as he ascended a small hillock，he saw at its foot a Lion feeding on the Calf. Terrified at the sight，he lifted his eyes and his hands to heaven，and said，“Just now I vowed to offer a lamb to the Guardian Deities of the forest if I could only find out who had robbed me；but now that I have discovered the thief，I would willingly add a fullgrown Bull to the Calf I have lost，if I may only secure my own escape from him in safety.”
