Passage: Dante was born in Florence, Republic of Florence, present-day Italy. The exact date of his birth is unknown, although it is generally believed to be around 1265. This can be deduced from autobiographic allusions in the Divine Comedy. Its first section, the Inferno, begins, "Nel mezzo del cammin di nostra vita" ("Midway upon the journey of our life"), implying that Dante was around 35 years old, since the average lifespan according to the Bible (Psalm 89:10, Vulgate) is 70 years; and since his imaginary travel to the netherworld took place in 1300, he was most probably born around 1265. Some verses of the Paradiso section of the Divine Comedy also provide a possible clue that he was born under the sign of Gemini: "As I revolved with the eternal twins, I saw revealed, from hills to river outlets, the threshing-floor that makes us so ferocious" (XXII 151–154). In 1265, the sun was in Gemini between approximately May 11 and June 11 (Julian calendar).Giovanni Boccaccio described Dante's appearance and demeanor as follows: "the poet was of middle height, and in his later years he walked somewhat bent over, with a grave and gentle gait. He was clad always in most seemly attire, such as befitted his ripe years. His face was long, his nose aquiline, and his eyes big rather than small. His jaws were large, and his lower lip protruded. He had a brown complexion, his hair and beard were thick, black, and curly, and his countenance was always melancholy and thoughtful."
