Omar Khayyamm, an Old Persian Poet

At the end of his speech, Clarence Darrow, recites a poem from an old Persian poet, Omar Khayyam. This man, Omar Khayyam was a philosopher, astronomer, mathematician and poet in the 1000s. He is one of the most infuential Iranian men ever, and has been noted to write over one thousand 4-line poems, all included in his posthumous book The Rubaiyat of Omar Khayyam. The poem, used by Clarence Darrow, is stated as follows: 

So I be written in the Book of Love,

I do not care about that Book above.

Erase my name or write it as you will,

So I be written in the Book of Love.
  

 Using this poem as an ending point to his speech was a brilliant idea for Mr. Darrow. This poem covienently summarizes everything he was trying to prove in a simple, but heart-warming manner. All Darrow wanted to do was help out other kids that had such a blind childhood that the kids he is defending had. He wants this poem to stick in everybody's hearts. Fight hatred with love, not with hatred. This is one of Darrow's biggest ideas throughout his speech. This idea even built on his other recurring theme, emotion. What he says at the end of the speech, including this poem, invokes emotion from all readers. Even the judge was hit with emotion right on the spot. Emotion and Love- two of Darrows big themes.
