in the sky is painted with the words in Greek "Εν τούτω νίκα" ("By this, conquer", better known as the Latin In hoc signo vinces) written next to it. The Battle of Milvian Bridge The Battle of Milvian Bridge shows the battle that took place on October 28, 312, following Constantine's vision. The Baptism of Constantine The third painting in the sequence, The Baptism of Constantine, was most likely painted by Gianfrancesco Penni, and shows the emperor being baptised by Pope Sylvester I in the Lateran Baptistery at Rome. This follows the account of Constantine's baptism given in the Acts of Sylvester and the Liber Pontificalis, rather than the alternate deathbed version recounted in Eusebius's Life of Constantine. In The Baptism of Constantine, Pope Sylvester I has the physical features of Pope Clement VII (1523-1534), who ordered the completion of the Raphael Rooms. The Donation of Constantine The final painting in the sequence, The Donation of Constantine, records an event that supposedly took place shortly after Constantine's baptism, and was inspired by the famous forged documents, incorporated into Gratian's Decretum, granting the Papacy sovereignty over Rome's territorial dominions. Stanza di Eliodoro The next room, going from East to West, is the Stanza di Eliodoro ("Room of Heliodorus"). Painted between 1511 and 1514, it takes its name from one of the paintings. The theme of this private chamber – probably an audience room – was the heavenly protection granted by Christ to the Church. The four paintings are: The Expulsion of Heliodorus from the Temple, The Mass at Bolsena, The Meeting of Pope Leo I and Attila, and The Deliverance of Saint Peter from Prison. In the first two of these frescoes, Raphael flatteringly includes his patron, Pope Julius II, as participant or observer; the third, painted after Julius's death, includes a portrait of his successor, Leo X. Raphael's style changed here from the Stanza della Segnatura. Instead of the static images of the Pope's library, he had dramatic narratives to portray, and his approach was to maximize the frescoes' expressive effects. He represented fewer, larger figures so that their actions and emotions have more direct impact on the viewers, and he used theatrical lighting effects to spotlight certain figures and heighten tension. The Expulsion of Heliodorus from the Temple In The Expulsion of Heliodorus from the Temple Raphael illustrated the biblical episode from II Maccabees (3:21–28) about Heliodorus, who was
