Dante, painted by
Giotto about 1320 AD
Since the time of the Romans, writers who lived in Italy had always written in Latin. Virgil wrote in Latin, Ovid wrote in Latin, and Gregory the Great and St. Benedict wrote in Latin. But gradually the language people actually spoke had changed, so that by the 1200s AD, when writers wrote in Latin, most people couldn't understand it without a translation into Italian. Dante was the first person to decide to write in Italian, instead. Dante showed that Italian was not just bad Latin, but a beautiful language suitable for writing poetry and literature.
Dante was born in Florence, in 1265 AD. He seems to have had a happy childhood, even though his mother died when he was only five years old. His parents were both from rich and powerful families in Florence, so unlike most kids in the Middle Ages in Europe, Dante got a good education, probably home-schooled by a private tutor. He studied both modern (medieval) poetry and Roman poetry, especially Virgil, which he loved.
When Dante was 12 years old, his father arranged for him to marry a girl named Gemma Donati, who was also from a rich family in Florence. Even at 12, Dante had already fallen in love with another girl, Beatrice, who was nine years old. But that didn't matter - he had to marry the girl his father chose for him.
When Dante was twenty, he married Gemma, and they ended up having about five children. Dante never got to know Beatrice very well, but he always stayed in love with her anyway. But Beatrice died in 1290, when Dante was 25 years old and she herself was only about twenty-two. Dante was very upset when Beatrice died.
Dante's father did let him hang out with a group of writers in Florence, and together this group began to write poetry in a new style - and in Italian. After Beatrice died, Dante tried to find reasons for why this terrible thing had happened, or some reason to go on living, by reading Roman philosophy.
Dante was from a powerful family, and he couldn't just mope around and write poetry all the time. He got involved in politics and fighting, and even helped win some battles for his side, the Guelphs. But in 1301, when Dante was 36 years old, his side lost power in Florence, and Dante had to leave Florence and go into exile. His wife, Gemma, and his children stayed behind in Florence.
Even though Dante never stopped trying to get back to Florence, he never managed it, and he spent the rest of his life travelling around other cities in northern Italy. During this time he wrote his great masterpiece, the Divine Comedy.
The Divine Comedy is divided into three parts: the Inferno, or Hell, Purgatorio, and Paradiso. Dante imagined that he himself was being given a tour of these places, and describes for us what he saw there. As he travels through the Inferno and the Purgatorio, the Roman poet Virgil is his guide - condemned to Hell forever because he was not a Christian. Dante sees all kinds of people there, and describes why they are in Hell and how they are suffering. Then his great love Beatrice comes to guide him to Paradise, where Dante sees the face of God.
Still in exile, Dante died in Ravenna in 1321 AD, when he was 56 years old. He may have died of malaria.
