[From the Writer’s Almanac]

On this day in 1819, 23-year-old John Keats (books by this author) composed what’s considered to be one of the most beautiful love letters ever written:

My dearest Girl,This moment I have set myself to copy some verses out fair. I cannot proceed with any degree of content. I must write you a line or two and see if that will assist in dismissing you from my Mind for ever so short a time. Upon my Soul I can think of nothing else — The time is passed when I had power to advise and warn you again[s]t the unpromising morning of my Life — My love has made me selfish. I cannot exist without you — I am forgetful of every thing but seeing you again — my Life seems to stop there — I see no further. You have absorb’d me. I have a sensation at the present moment as though I was dissolving — I should be exquisitely miserable without the hope of soon seeing you. I should be afraid to separate myself far from you. My sweet Fanny, will your heart never change? My love, will it? I have no limit now to my love — You note came in just here — I cannot be happier away from you — ‘T is richer than an Argosy of Pearles. Do not threat me even in jest. I have been astonished that Men could die Martyrs for religion — I have shudder’d at it — I shudder no more — I could be martyr’d for my Religion — Love is my religion — I could die for that — I could die for you. My Creed is Love and you are its only tenet — You have ravish’d me away by a Power I cannot resist: and yet I could resist till I saw you; and even since I have seen you I have endeavoured often “to reason against the reasons of my Love.” I can do that no more — the pain would be too great — My Love is selfish — I cannot breathe without you.
Yours for ever

John Keats
