Infelix ego ("Alas, wretch that I am") is a Latin meditation on the Miserere, Psalm 51 (Psalm 50 in Septuagint numbering), composed in prison by Girolamo Savonarola by 8 May 1498, after he was tortured on the rack, and two weeks before he was burned at the stake in the Piazza della Signoria in Florence on 23 May 1498. The prison authorities had spared only his right arm during the preliminary torture, so that Savonarola would be able to sign his confession: after doing so, and in a state of despair at not being strong enough to resist the pain of his prolonged torture, he wrote Infelix ego and a portion of a companion meditation, Tristitia obsedit me, on Psalm 30. He was executed before he was able to complete Tristitia obsedit me. Savonarola was devastated at his own personal weakness in allowing the physical torture to overcome his will. After signing the confession, recanting his beliefs, and even denying that his prophecies had been sent by God Himself, he felt the need to prostrate himself before his God and beg for forgiveness. Penitential Psalm 51 (50 in the Septuagint numbering), the Miserere, provided the inspiration for his long and impassioned cry for mercy, a document which was to become highly influential in the years before the Reformation, especially in music history. On 23 May 1498, Savonarola and two other friars who were his supporters were led out of their cells to the public square beside the Palazzo della Signoria. After their crimes were read to them, they were hanged in chains, and then burned, with the ashes being hurled into the Arno so that no relics would be recoverable by the crowds of the fanatical reformer's former supporters. Almost immediately, however, Savonarola's two meditations were in print: Laurentius de Rubeis produced one of the first prints, in Ferrara, Savonarola's birthplace, a town which continued to venerate him well into the 16th century. Infelix ego begins, in translation: Reception and influence Infelix ego and its incomplete companion work Tristitia obsedit me spread quickly throughout Europe after Savonarola's execution. Of all his writings they became the most famous, appearing in 15 editions in Italy by 1500, and being translated into most European languages during the 16th century. Martin Luther was impressed by the pair of meditations, and wrote a preface to them in his 1523 publication of them in Wittenberg. His
