Zuzanna Ginczanka's last poem, "Non omnis moriar..." ("Not all of me shall die"), written shortly before her execution by the Nazis in the last months of World War II, is one of the most famous and unsettling texts in modern East European literature: a fiercely iconic last will and testament that names the person who betrayed her to the occupying authorities as a Jew, it exposes the hypocrisy at the heart of the Polish nationalist myths. Ginczanka's linguistic exuberance and invention - reminiscent now of Marina Tsvetaeva, now of Marianne Moore or Mina Loy - are as exhilarating as the passionate fusion of the physical world and the world of ideas she advocated in her work. 'Firebird' brings together many of Ginczanka's uncollected poems and presents 'On Centaurs', her sole published book, in its entirety.
