moved to bring in oxygen and blood plasma. His last words were reportedly, "Pray. Pray that this regrettable situation for the church may end". When Pius XII was interred, the small crucifix and rosary that he held in his hands as he died were buried with him. On the last full day of his life, his temperature rose steadily and his breathing became difficult. At 3:52 AM (02:52 GMT) on Thursday, 9 October, a Feast of Saint Denis of Paris, he gave a smile, lowered his head and died. The cause of death was recorded as acute heart failure. Domenico Tardini prayed the Magnificat Anima mea dominum, the Virgin Mary's praise of the Lord, in Latin. His doctor Gaspanini said afterwards: "The Holy Father did not die because of any specific illness. He was completely exhausted. He was overworked beyond limit. His heart was healthy, his lungs were good. He could have lived another 20 years, had he spared himself." Spain declared ten days of mourning; Italy declared three days of mourning and the closure of offices and schools as a sign of respect; Cuba declared three days of mourning. The Testament of Pope Pius XII was published the month of his death. Botched embalming Pius XII's physician, Riccardo Galeazzi-Lisi, reported that the pontiff's body was embalmed in the room where he died using a novel process invented by Oreste Nuzzi. Pope Pius XII did not want the vital organs removed from his body, demanding instead that it be kept in the same condition "in which God created it". According to Galeazzi-Lisi, this was the reason why he and Nuzzi, an embalmer from Naples, used an atypical approach with the embalming procedure. In a controversial press conference, Galeazzi-Lisi described in great detail the embalming of the body of the late pontiff. He claimed to have used the same system of oils and resins with which the body of Jesus Christ was preserved. Galeazzi-Lisi asserted that the new process would "preserve the body indefinitely in its natural state". However, whatever chance the new embalming process had of efficaciously preserving the body was obliterated by intense heat in Castel Gandolfo during the embalming process. As a result, the body decomposed rapidly and the viewing of the faithful had to be terminated abruptly. Galeazzi-Lisi reported that heat in the halls, where the body of the late Pope lay in state, caused chemical reactions
