Anecdotes
Elected pope in 1254 under the name Alexander IV, Rinaldo di Jenne was the nephew of Pope Gregory IX: the family of the counts of Segni had already given the Church several popes, including Innocent III. Nepotism and the great Roman families played a central role in the election of the sovereign pontiffs in the 13th century.
As early as 1255, Alexander IV canonized Clare of Assisi, the faithful companion of Saint Francis and founder of the Poor Clares, barely two years after her death. This swift gesture shows the pope's deep attachment to the then very recent mendicant orders.
Alexander IV almost never managed to reside in Rome itself: the city was too turbulent and hostile. He spent most of his pontificate in Viterbo and Anagni, towns in Latium where the papacy found refuge.
In 1255, the pope firmly defended the Franciscan and Dominican friars against the masters of the University of Paris who wanted to drive them out of teaching. Through his bull “Quasi lignum vitae”, he upheld their right to teach, marking a victory for the mendicant orders in the universities.
Worried about the advance of the Mongols, who had devastated Poland and Hungary, Alexander IV sought to organize the resistance of Christendom and sent appeals to the princes of Europe to prepare for a possible invasion.

Daily Life
Morning
The pope began his day early with prayer and the celebration of Mass, surrounded by his chaplains. The morning was often devoted to reviewing the affairs of the Church and receiving messengers who had come from all across Christendom.
Afternoon
The afternoon was spent in consistory, the assembly of cardinals where the great decisions were debated: appointments, conflicts, and bulls to be drafted. The papal chancery worked tirelessly to draw up the official letters.
Evening
In the evening, the pope withdrew for further prayers and the office of Vespers. He might also grant private audiences to ambassadors, bishops, or members of religious orders who had come to seek his arbitration.
Food
The diet of a medieval pope was refined but shaped by the many days of fasting and abstinence imposed by the Church. Bread, fish, vegetables, fruit, and wine made up the everyday fare, with meat set aside during Lent and on vigils.
Clothing
On an everyday basis, the pope wore a white cassock and a mozzetta; for ceremonies, he donned precious vestments — the embroidered cope, the tiara, and the Fisherman's Ring. White symbolized his purity and his office.
Housing
Unable to reside in Rome, Alexander IV lived in the papal palaces of Viterbo and Anagni. These fortified residences offered both security and comfort, with a chapel, audience halls, and a library.
