公元前2708年的一天,神采奕奕、容光焕发的埃及国王胡夫举行了盛大的宴会。仆人们在厨房与客厅之间匆忙穿梭。突然间,在厨房忙碌的一位小伙计一不小心,将刚刚炼好的羊油打翻在灶坑旁的炭灰里。小伙计惟恐遭到国王惩戒,情急之下,连忙用手将混有羊油的炭灰一把一把地捧了出去,以免被人发现。当小伙计捧完炭灰洗手时,奇怪的事情发生了,他的手变得特别干净,甚至连以前很难洗掉的污垢都不见了。 On the day of 2708 BC, the splendid and radiant Egyptian king Khufu held a grand banquet. The servants rushed between the kitchen and the living room. Suddenly, a young man who was busy in the kitchen accidentally knocked down the freshly-made oil on the char in the stove pit. The young man feared that he would be disciplined by the king. In desperation, he quickly took out the soot mixed with goat oil, so as not to be discovered. When the boy washed his hands with soot, strange things happened. His hands became particularly clean. Even dirt that had been difficult to wash away was gone.
