Jacek Podsiadło (born 1964 in Szewna) is a Polish poet, writer, translator and essayist.
 Sometimes he uses a pen name Jac Po.
 He is one of the poets of the famous Polish "bruLion" generation.
 Originally he was influenced by Frank O'Hara, but later he developed his own original style.
 He is a very prolific writer, and also a winner of many Polish literary prizes (Georg Trakl prize, 1994; Kościelski prize, 1998; Czesław Miłosz prize 2000; he was also nominated for the Nike Award thrice).
 He had many professions, he now works in the Opole radio station.
 Between 2000 and 2007 he wrote feuilletons for Tygodnik Powszechny.
Wilhelm Killmayer, a German composer, wrote several song cycles, which form a substantial part of his compositions.
 The earliest cycle dates from 1953, the last was completed in 2008.
 He set poems by German romantic writers such as Friedrich Hölderlin and Joseph von Eichendorff, but was also inspired by French, Greek and Spanish poems, and by texts from the 20th-century poets Georg Trakl and Peter Härtling.
 He used mostly piano to accompany a singer, but also added percussion or other instruments, and scored some cycles in a version for voice and orchestra.
 His "Hölderlin-Lieder", setting poems from the author's late period, were performed at major festivals and recorded.
"Grodek" is a poem about World War I written by Georg Trakl, an Austrian Expressionist poet.
 It was one of his last poems, if not his very last poem.
The Bloody Chamber (or The Bloody Chamber and Other Stories) is a collection of short fiction by Angela Carter.
