In 1380, Saint Bernardino of Siena was born — a great Franciscan preacher, witness to the name of Jesus (IHS), and a key figure in a remarkable period of spiritual renewal. Unjustly accused of heresy, he defended himself in Rome and was acquitted. He stayed at the convent of Ara Coeli, next to the Capitoline Hill, where his dedicated chapel still stands today, masterfully frescoed by Pinturicchio with scenes from his life and evangelizing mission. During the pontificate of Pope Martin V, the Church emerged from the Western Schism, and Rome entered a new era of artistic, spiritual, and cultural flourishing. This rebirth also saw the construction of the Sistine Chapel — a symbol of the union between faith and art — where Michelangelo painted the ceiling and the Last Judgment, works that reflect the redeemed beauty of man created by God. A journey among saints, artists, popes, and Church crises, to rediscover Christian hope in a world transfigured by divine light.
