德国大诗人海涅在长诗《奴隶船》中描写了一个血腥的场景。望柯克(黑奴贩子)喊道:“水上的看护长(医生),我那些可爱的黑人近来怎样?”医生说:“我特来向你报告,昨天夜里,死亡率显著增高。过去平均每天死两个,昨天却有七名死亡,是四男三女……”望柯克叹息着,把医生的话打断,“怎样才能减少这个损失?怎样能阻止死亡率升高?”医生回答说:“……有许多黑人死亡是由于忧郁,他们感到致命的无聊,来点儿空气、音乐和舞蹈,他们的病就能够治疗。” The German great poet Heine describes a bloody scene in the long poem “The Slave Ship.” Wang Keke (black slave trader) shouted: “How can I see the lovely blacks in the water (the doctor)?” The doctor said: “I have come to report to you that the mortality rate has risen significantly last night.” In the past, there were an average of two deaths a day, and yesterday there were seven deaths. It was four men and three women....“” Kirkke sighed and interrupted the doctor’s words. “How can we reduce this loss? How can we prevent deaths from rising? Gao?”The doctor replied: “... There are many black deaths because of melancholy, they feel deadly boring, come to air, music and dance, and their illness can be treated.”
