Requiem: A Hallucination (Portuguese: Requiem: uma alucinação) is a 1991 novel by the Italian writer Antonio Tabucchi. Set in Lisbon, the narrative centres on an Italian author who meets the spirit of a dead Portuguese poet, never named but strongly indicated to be Fernando Pessoa. Tabucchi wrote the book in Portuguese. Alain Tanner directed a 1998 film adaptation, also called Requiem. Source: Wikipedia (en)
