Help on a Harold Bloom quote!!

I have seen it written in various places that Harold Bloom once referred to John Milton as "the great Inhibitor, the Sphinx who strangles even strong imaginations in their cradles."

Could anyone PLEASE help me find the source of this quote? In what work did Bloom write this?

Thank you all!

Hi Ser...I think it comes from his 'The Western Canon'. I think it appears in the first chapter "about the canon"
