Question: Why did Roncalli leave the city where the creator of The Entombment died?

Knowledge 1: The Entombment (Titian, 1559)
The Entombment is a 1559 painting by Titian, commissioned by Philip II of Spain. In this painting, Tizian uses the mature style characterized by the use of broad brushwork and brilliant colours. The figure holding Christ body is Nicodemus, the Jewish elder that secretly visited Jesus at night to learn about his teachings. The figure of Nicodemus bears the traits of the artist himself. This could have been inspired by Michelangelo's idea in his unfinished Pietà from 1550, depicting himself as Nicodemus, supporting the body of Christ displayed in the Cathedral in Florence. The stone sarcophagus where Christ body is placed is decorated with depictions of Cain and Abel and the Sacrifice of Isaac - themes that according to the Christian faith predicted the sacrifice of Jesus.

Following the death of Pope Pius XII on 9 October 1958, Roncalli watched the live funeral on his last full day in Venice on 11 October. His journal was specifically concerned with the funeral and the abused state of the late pontiff's corpse. Roncalli left Venice for the conclave in Rome well aware that he was papabile,[b] and after eleven ballots, was elected to succeed the late Pius XII, so it came as no surprise to him, though he had arrived at the Vatican with a return train ticket to Venice.[citation needed] [SEP] Knowledge 3: Roncalli High School (Indiana)
Roncalli High School is a Catholic high school located in Indianapolis, Indiana. It is located on the south side of Indianapolis and run by the Roman Catholic Archdiocese of Indianapolis. Roncalli is named for Pope John XXIII, Angelo Giuseppe Roncalli.
Knowledge 1: The Martyrdom of Saint Lawrence (Titian)
The Martyrdom of Saint Lawrence is a 1558 painting by Titian, now in the church of I Gesuiti in Venice. It so impressed Philip II of Spain that he commissioned a second version in 1567 for the basilica at El Escorial. [SEP] Knowledge 2: Pope John XXIII
