"such stuff as dreams are made on" 出自莎士比亚的哪部作品,原文是什么,

莎士比亚的戏剧《暴风雨》,第四幕第一场,普洛斯彼罗的台词.普洛斯彼洛施展法术,召唤来精灵们,展示了神奇美丽的幻境.
表演结束时普洛斯彼罗说,“我们的狂欢已经结束.我们的这些演员,我曾经告诉过你,原是一群精灵,他们都已经化为轻烟消散了.如同这虚无缥缈的幻境,入云的阁楼,瑰伟的宫殿,庄严的庙堂,甚至地球自身,以及地球上所有的一切,都将同样消散,如同这一场幻境,连一点烟云的影子都不会留下.构成我们的材料也就是构成梦幻的材料,我们短暂的一生,前后都环绕在沉睡之中.”
Our revels now are ended.These our actors,
As I foretold you ,were all spirits,and
Are melted into air,into thin air ,
And like the baseless fabric of this vision,
The cloud capped towers,the gorgeous palaces,
The solemn temples,the great globe itself,
Yea,all which it inherit,shall dissolve,
And like this insubstantial pageant faded,
Leave not a rack behind .We are such stuff
As dreams are made on,and our little life
Is rounded with a sleep.
