Unfortunately few letters have been preserved of Cavafy. Three collections of letters written between 1882 and 1886 to Cavafy are known, but not what he wrote. These collections correspond to their youth. We have three collections of letters written Cavafy in the last decade of his life. They are directed to E. M. Forster, Mario Vaianos and Aleko Sengopulos. This article contains an introduction to the collection of letters to Vaianos.
