Quiricus and Giulitta to Bishop Rainerius (1074–1084), and ordered all its monks and laypersons to obey him in all things.

In 1215, when the monks had murdered their abbot and dissipated their income, Pope Innocent III had them expelled, and introduced the Premonstratensians in their place.

[7] In 1228, Pope Gregory IX (dei Conti di Segni) was driven out of Rome by the supporters of the Emperor Frederick II; he spent a month in April and May in exile in Rieti, before moving to other places of refuge.

[11] On 28 November 1298, a major earthquake struck Rieti, Spoleto and Città di Pieve, causing considerable loss of life and destruction of buildings.

However, after Cardinal Colonna died on 26 September 1508, Pope Julius II reactivated the diocese of Città Ducale on 16 October 1508.

His plan was modest, a student body of twenty-six, with an appropriate number of teachers of the humanities, philosophy, and theology.

In that year, a deacon of the church wrote to Pope Gregory I, requesting that he order the relics of Ss.

Hermas, Hyacinth and Maximus be enshrined in the cathedral, a task which the Pope entrusted to Bishop Chrysanthus of Spoleto, presumably because the See of Rieti was vacant.

[15] This cathedral was subject to the unwelcome attentions of the Goths, the Lombards, and the Saracens, leaving it in a dilapidated condition.

[18] The upper church was consecrated by Pope Honorius III, who had been driven out of Rome and was living in exile in Rieti, on 9 September 1225.

[24] Bishop Giorgio Bolognetti summoned and presided over a diocesan synod in Rieti on 24–25 September 1645, and had the decrees published.
