phase saw Mantegna alone at work, as Pizzolo had also died in 1453. Mantegna completed the Stories of St. James, frescoed the central wall with the Assumption of the Virgin and then completed the lower sector of the Stories of St. Cristopher begun by Bono da Ferrara and Ansuino da Forlì, where he painted two unified scenes: the Martyrdom of St. Christopher. In 1457, Imperatrice Ovetari sued Mantegna, accusing him of having painted, in the Assumption, only eight apostles instead of twelve. Two painters from Milan, Pietro da Milano and Giovanni Storlato, were called in to solve the matter. They justified Mantegna's choice due to the lack of space. Around 1880 two scenes, the Assumption and the Martyrdom of St. Christopher, were detached from the walls. During World War II the two frescoes were stored in a separate location, and were thus saved from the destruction of all the rest of the cycle during an Allied air bombardment of 11 March 1944. The destroyed scenes are known today through black-and-white photographic reproductions. Description Architecture The Chapel consists of an entrance room with a rectangular base, covered by a cross vault which is connected to a pentagonal apse introduced by an arch, where are a circular opening and four windows which illuminate the chapel. Frescoes The Chapel was dedicated to the saints James and Christopher. The two lateral walls were dedicated to the stories of each saint, with six episodes placed on three sections. The upper one consisted of a round lunette. Despite the presence of several painters in the work, the layout of the cycle is generally attributed to Mantegna, who devised the architectural frames. The stories portrayed were inspired by Jacobus de Voragine's Golden Legend. The northern wall was entirely painted by Mantegna and included: Vocation of the Saints James and John St. James Preaching St. James Baptizes Hermogenes Judgement of St. James Miracle of St. James Martyrdom of St. James The southern wall included the Stories of St. Christopher: St. Christopher Leaving the King by Ansuino da Forlì (attributed) St. Christopher and the King of the Devils by Ansuino da Forlì (attributed) St. Christopher Ferrying the Child by Bono da Ferrara (signed) St. Christopher Preaching by Ansuino da Forlì (signed) Martyrdom of St. Christopher by Andrea Mantegna Transportation of St. Christopher Beheaded Body by Andrea Mantegna. On the central wall, where is the window, is a representation of
