The first and only collection of poems to be published by the Portuguese writer Camilo Pessanha during his lifetime, Clepsydra is the crowning achievement of the Portuguese symbolist movement. Meditating on the inexorable flow of time, Pessanha sets the music of his verses against the babbling water clock that gives the book its title. This new annotated translation by Adam Mahler recreates in English the haunting melodies and evocative dreamscapes that were widely admired and emulated by Portuguese modernists such as Fernando Pessoa. In addition to the thirty poems of the original 1920 publication, the bilingual volume features eighteen compositions that appeared in subsequent editions, making it the most comprehensive English translation of Clepsydra to date.
