Dante Alighieri
In the year 1300, a man named Dante Alighieri claimed to have walked through Hell. He wrote that he was midway upon the journey of his life when this vision occurred. The text implies he was about thirty-five years old at that moment. This single line from his poem Inferno serves as the primary clue for historians trying to pin down his birth date. They calculate that if he was thirty-five in 1300, he must have been born around May 1265. No official record exists to confirm this exact day or month. Some verses in his later work Paradiso suggest he was born under the sign of Gemini. Astronomers note that the sun was indeed in that zodiac sign between May 11 and June 11 during the Julian calendar year of 1265. This calculation remains the most accepted theory among scholars today.
Florence in the late thirteenth century was a city torn apart by civil war. Two factions fought for control over the republic. One group called themselves the Guelphs and supported the Pope. The other group were known as the Ghibellines and backed the Holy Roman Empire. Dante's family belonged to the Guelph faction. His father Alighiero di Bellincione worked as a moneylender and businessman. He held little public power, which may have protected them from reprisals after the Ghibellines briefly seized Florence in 1260. The Guelphs eventually won back the city at the Battle of Benevento in 1266. Dante himself took up arms against the Ghibellines at the Battle of Campaldino on the 11th of June 1289. He served as a cavalryman responsible for leading the first attack. This military service allowed him to join the Physicians' and Apothecaries' Guild around 1295. That guild membership gave him the right to hold public office in his home city.
Dante studied Tuscan poetry and admired the works of Guido Guinizelli. He referred to this Bolognese poet as his literary father in Purgatorio XXVI. He also discovered the Provençal poetry written by troubadours like Arnaut Daniel. These influences shaped his early poetic identity before he found his own voice. At age eighteen, he met Guido Cavalcanti and other poets who formed a group known as the Dolce Stil Novo or sweet new style. Dante coined this term himself to describe their shared approach to love poetry. They explored aspects of love that had never been emphasized before. Beatrice Portinari became the central figure of this movement. She was the daughter of Folco Portinari. Dante claimed to have fallen in love with her at first sight when they were both children. He wrote many sonnets dedicated to her but never mentioned his actual wife Gemma di Manetto Donati in any poem. When Beatrice died in 1290, Dante sought refuge in Latin literature instead of continuing his courtly love poems.
Political tensions within Florence erupted into violence after the Guelphs defeated the Ghibellines. The victorious faction split into two groups called White Guelphs and Black Guelphs. Dante belonged to the White party led by Vieri dei Cerchi. The Black faction was commanded by Corso Donati. Pope Boniface VIII planned a military occupation of Florence to support the Blacks. Charles of Valois entered the city on the 1st of November 1301. A new government installed by the Blacks condemned Dante to exile in March 1302. He faced a large fine and permanent banishment from his home. If he ever returned without paying, he would be burned at the stake. Dante refused to pay the fine because he believed he was innocent. His assets were seized by the Black Guelphs while he was still in Rome. He spent years traveling through Verona, Sarzana, and Lucca as a guest of various patrons. During this period of displacement, he began writing his masterpiece. An early notice by Francesco da Barberino suggests composition started around 1314 or 1315. The first part, Inferno, had been published by 1317 according to quoted lines found in Bologna records.
Dante wrote several prose works during his exile that explored philosophy and politics. One unfinished treatise called Convivio translates to The Banquet. It contains commentary on his longest poems and argues for universal monarchy under Henry VII of Luxembourg. Another work titled De Vulgari Eloquentia discusses the use of vernacular language instead of Latin. This text defended the Florentine dialect as suitable for high literature. A third major work named Monarchia argued for a single global ruler to ensure peace. This book was condemned as heretical after his death and placed on the Index Librorum Prohibitorum until 1881. Dante also wrote Eclogues addressed to Giovanni del Virgilio. These were two poems written in Latin. He composed other minor works like Il Fiore and Detto d'Amore which summarized Ovid's Metamorphoses. His theological treatise Quaestio de Aqua et Terra discussed the arrangement of land and ocean. All these writings demonstrate his deep engagement with scholastic philosophy while he lived away from Florence.
Guido II da Polenta invited Dante to stay in Ravenna in 1318. The city prince offered him protection and hospitality. Dante died there on the 14th of September 1321 at the age of about fifty-six. He had contracted quartan malaria while returning from a diplomatic mission to Venice. His three children attended him during his final days along with friends and admirers. He was buried in the Church of San Pier Maggiore which later became known as the Basilica di San Francesco. In 1483, Bernardo Bembo erected a tomb for him. A verse dedicated to Florence appears on that grave. Later attempts to move his remains caused controversy. Bertrand du Pouget classified Monarchia as heretical in 1329 and tried to have the bones burned. Allies prevented this destruction. Florence built an empty tomb in Santa Croce in 1829 but the body remained in Ravenna. A copy of his death mask has been displayed since 1911 though scholars believe it dates to 1483.
Giovanni Boccaccio wrote the first formal biography of Dante after 1348. This work included many statements now considered unreliable by modern research. Yet earlier accounts existed in the chronicles of Giovanni Villani. The nineteenth century saw a revival of interest in his life and works. Thomas Carlyle profiled him in On Heroes, Hero-Worship, & the Heroic in History published in 1841. Leigh Hunt and Henry Wadsworth Longfellow translated his poetry during this era. Pope Benedict XV issued an encyclical named In praeclara summorum in 1921 calling him one of the Catholic faith's celebrated geniuses. Pope Paul VI promulgated a Latin letter titled Redemptoris Mater in 1965 dedicated to Dante's figure. An Italian dreadnought battleship completed in 1913 bore his name. In 2007 forensic engineers reconstructed his face showing features different from previous assumptions. Florence officially apologized for expelling him seven centuries later in May 2021 through a symbolic re-trial held virtually.
