CHAPTER 6 The Papal Hospital: Santo Spirito in Sassia

Lotharius, a Father with a great heart, was made with the name of Innocent III—a man whom no more learned or sagacious pope ever suc- ceeded until Sixtus. Robert Flemmyng, Lucubraciunculae Tiburtinae1

It is a bastion of the history of Renaissance that in the fifteenth century the Vatican became the permanent seat of a papacy forging the masterwork of its absolutist rule. The Renaissance , however, only completed a project launched by Innocent III (1198–1216) two and a half centuries earlier. Times had changed between the early thirteenth century and the late fifteenth, but certain conditions seemed to offer themselves with renewed poignancy. Papal primacy was under siege, the attacks now coming from within the ranks of the Church. The Great Schism of the Church (1378–1417), when rival candidates con- tended the papal throne, had brought in its wake attempts to curtail papal authority by subjecting it to a council of bishops. The Council of Pisa, in 1409, and that of Constance, which began in 1414, imposed the view that it was not the pope, but the episcopal council as a whole who received its author- ity directly from Christ, and that the pope was bound to obey its decrees. The Councils’ success in securing the withdrawal or deposition of three rival popes supplied a strong argument in favor of conciliar authority, and the sentiment that regularly convoked Councils were the form of Church government most in harmony with the needs of turbulent times gained rapid ground.2 Skepticism about papal theories blossomed in the conducive climate of humanism, as the great Latinists scrutinized with newfound competence ancient texts. , conciliar theorist and philosopher, who

When making their case for Roman primacy at the Council of — which in 1439 brought together Eugene IV (1431–1447), the Eastern Emperor John VIII Palaeologus (1425–1448), and the patriarchs of the Eastern Churches seeking common doctrinal ground—papal delegates prudently omitted men- tion of the Donation. Between 1439 and 1440, Lorenzo Valla dealt the Donation the final blow, demonstrating that the vernacular Latin of the document could not have been written in a fourth-century imperial chancellery, but must have been produced in much later medieval times.3 Papal control over urban territory was equally disputed. The Senate, the civic government of Rome, did not formally or even substantially challenge papal authority. Stefano Porcari’s short-lived conspiracy to reinstate a repub- lic in 1453 was the last and an already illusory attempt to overthrow papal

I have Il Kim to thank for this reference. For a translation of relevant parts of the argument by Valla—who directly challenged the ruling pope, Eugene IV, see Lorenzo Valla, The Profession of the Religious and the Principal Arguments from the Falsely- Believed and Forged Donation of Constantine, trans. Olga Zorzi Pugliese (Toronto: Centre for and Renaissance Studies, 1985), 63–72, and p. 68 for Eugene in particular. An insightful discussion that identifies the significance of Valla’s argument against the Donation for history writing is in: Carlo Ginzburg, History, Rhetoric, and Proof (Hanover: Brandeis University Press, 1999); see the chapter on “Lorenzo Valla on the ‘Donation of Constantine,’ ” 54–70.
