A university press in Melbourne, Australia, wrote to me asking if I know who wrote these lines? They were told the lines were written by John Donne, but they have not been able to locate the text. I have asked other Donne scholars about the lines, and the guesses range from George Herbert to Edgar Guest. The lines don't remind me of Donne,, but they indeed may be hidden away somewhere in his work. Please let us know if the lines ring familiar.
Wonderful! Thank you so much. The "Don Juan" connection is intriguing.
The scholar, who lives in Melbourne, said the lines appeared in a diary in 1947 by a French writer, Henri Thomas. It seems that Thomas attributed the lines to Donne. Her doctoral dissertation, completed at London University, focused on his correspondence. I have written her about the Donne website and your reply.
