The British poet Rupert Brooke (1887-1915) was famed for his World War I sonnets and poetry as well as his extreme good looks. His poem, "Jealousy," first appeared in the "1908-1911" section of his initial book of poetry, Poems 1911, published in 1911. I have not been able to determine in what year "Jealousy" was actually written. Brooke, who was called "the handsomest young man in England" by William Butler Yeats, died tragically at the age of 27 while in the service of the Royal Navy. He was part of the expeditionary force on its way to Gallipoli when he contracted sepsis from a mosquito bite.
