This was his method of doing it. He has said in cipher that he has left his signature in everything in which he had a hand. Although the Elegy is obviously written on the death of a friend, it still was used to tell a part of Bacon's own tragic story for the public with eyes to see. Lines 90 to 100 have two of his signatures. I find no cipher in that.
Life is a Bubble.
A bit awkward, perhaps. He was always experimenting with different poetic patterns. It may have been written before he started using hidden cipher clues. There is so much more that can be said on this subject in spite of the fact that the Friedmans could not find a cipher in Shakespeare. I thank Professor Foster and Dr. Taylor for making these interesting poems available to the public.
