Now I Am Become Death, the Destroyer of Worlds — J. Robert Oppenheimer
Oppenheimer famously quoted this from The Bhagwat Geeta in the context of the nuclear bomb. The way this sentence is structured feels weird to me. “Now I am Death” or “Now I have become Death” sound much more natural in English to me.
Was he trying to simulate some formulation in Sanskrit that is not available in the English language?
He was using some fancier and older form of English. I believe it is grammatically correct, we just don’t use those forms anymore. The first translation of the Gita is from 1785 and it is one of the most translated Asian texts. Famously, every translator places emphasis and projects their own personal worldview unto the text. Though Oppenheimer actually could read and had read the Bhagavad Gita in its original Sanskrit, so he was just giving it his own personal twist.
If “I have become” and “I am” are both valid translations then “I am become” seems like fairly minor literary license.
I think it sounds cooler. Powerful beings are not supposed to sound ordinary.
