An Italian version of Johann Wolfgang von Goethe's Iphigenie in Tauris, long believed to be lost for nearly two centuries, has been discovered in the personal library of Goethe himself. The document, titled Ifigenia in Tauride: Tragedia di Göthe recata in Italiano, was found in the Herzogin Anna Amalia Bibliothek in Weimar, a renowned library associated with Goethe's legacy. It had been cataloged under the call number "Ruppert 1852." A watermark on one of the pages dated its creation to around 1825. The translation was attributed to Alessandro Poerio, an Italian poet and prominent figure in the Risorgimento, the 19th-century movement for Italian unification. Poerio had visited Weimar in 1825 and 1826 and was known to have attended the salon of Ottilie von Goethe, Goethe's stepdaughter. Poerio personally presented the two texts to Goethe, who received them with great enthusiasm. The Italian version of Iphigenie in Tauris had been thought lost, but it had remained in Goethe's library all along. The identification of the manuscript was made by Francesca Fabbri, an Italian art historian, who traced the attribution back to a study by Reinhold Köhler, a librarian from the 19th century. This discovery offers new insights into the cultural exchanges between Germany and Italy during the Weimar classicism period, a time of intellectual and artistic flourishing in Germany. Meanwhile, another text by Poerio, La sposa di Corinto, had been published in the magazine Chaos some years later, but the Iphigenie manuscript had been lost to history. The rediscovery of both texts, which had been separated for over a century, will be featured in an exhibition in Rome. The exhibition aims to highlight the significance of these works and their role in the broader context of European literary history. A scientific edition of Poerio's translation of Iphigenie in Tauris is planned for 2027, providing scholars and the public with a chance to study and appreciate this long-lost work. This discovery not only enriches the understanding of Goethe's influence beyond Germany but also sheds light on the contributions of Italian intellectuals during the 19th century.
