de Santo Tomás de Nuestra Señora del Santísimo Rosario into the rank of a university. It is now the University of Santo Tomás in Manila, the oldest existing in Asia. In 1650, Innocent X celebrated a Jubilee. He embellished Rome with inlaid floors and bas-relief in Saint Peter's, erected Bernini's Fontana dei Quattro Fiumi in Piazza Navona, the Pamphili stronghold in Rome, and ordered the construction of Palazzo Nuovo at the Campidoglio. Innocent X is also the subject of Portrait of Innocent X, a famous painting by Diego Velázquez housed in the family gallery of Palazzo Doria (Galleria Doria Pamphili). This portrait inspired the "Screaming Pope" paintings by 20th-century painter Francis Bacon, the most famous of which is Bacon's Study after Velázquez's Portrait of Pope Innocent X. Olimpia Maidalchini Olimpia Maidalchini was married to Innocent X's late brother, and was believed to be his mistress because of her influence over him in matters of promotion and politics. This state of affairs was alluded to in the Encyclopædia Britannica 9th edition (1880): German historian Leopold von Ranke concluded that she was not Innocent X's lover. Death and legacy In his later years, Innocent X suffered from gout, causing him intense pain and severely restricting his movements. The eighty-year-old pontiff's health began to decline in August 1654. By the evening of 26 December his condition had deteriorated to the extent that the family was summoned. On 27 December, he blessed his nephew, niece, and their children, and then had a brief meeting with Cardinals Flavio Chigi and Decio Azzolino. That night he had a little rest, though his condition did not improve. On 28 December, Innocent X received the Last rites and expressed his desire to take leave of the cardinals. In anticipation of the Pope's expected death many of the cardinals had already gathered in Rome in advance of a subsequent conclave. Thirty-nine gathered at his bedside at the Quirinal Palace. On 1 January 1655, Mass was celebrated at the pope's bedside, and the same was done on 6 January, when Innocent X also received the Viaticum for the last time. Secretary of State Chigi, who had been in attendance during the last twelve days, Prefect of the Sacred Palace Bishop Scotti, and Sacristan Monsignor Altini, as well as, various attendants were present when the Pope died on the night of 6 January 1655.
