Gerardo da Sesso

Gerardo da Sesso (c. 1160 – 16 December 1211)

Gerardo da Sesso was an Italian monk, bishop-elect, and cardinal-bishop-elect of the Catholic Church, known for his significant role in the reform of the Lombard clergy and his involvement in the political landscape of early 13th-century Italy. Born around 1160 in Reggio nell'Emilia into the prominent Emilian family of Da Sesso, which had Ghibelline leanings, Gerardo received a theological education and authored his own summa.

Life and Historical Context

Gerardo's early career saw him hold the title of 'magister' by 1192, indicating formal education, possibly in Paris or Bologna. He developed ties with the schools of Cremona and later joined the Cistercian order, becoming the abbot of Tiglieto from 1205 to 1209. His influence grew significantly when Pope Innocent III appointed him 'visitator et provisor Lombardie' in 1205 or 1206. In this capacity, he was tasked with conducting visitations and inquisitions to reform the clergy in northern Italy, working actively in various dioceses.

Major Contributions and Roles

As a reformer, Gerardo da Sesso was instrumental in implementing papal directives for clerical conduct. He mediated disputes, investigated the conduct of bishops, and participated in judgments against ecclesiastical figures. Notably, he was involved in the preaching of a new crusade in Lombardy, which became part of the Fifth Crusade. He also acted as an arbitrator in conflicts between cities like Genoa and Pisa.

In 1209, he was elected bishop-elect of Novara, accepting the position upon the insistence of Pope Innocent III, though he was never consecrated. Following the excommunication of Emperor Otto IV in 1210, Gerardo became a vocal supporter of Frederick II, the Ghibelline candidate for the imperial throne. In April 1211, Pope Innocent III further promoted him to cardinal bishop-elect of Albano and appointed him as apostolic legate of Lombardy. One of his first acts as legate was to officially approve and defend the Humiliati.

Gerardo was elected archbishop of Milan in May 1211, but the election was deemed irregular, and neither he nor the Pope accepted it. He continued his legatine duties, enforcing excommunications and adjudicating disputes until his death in Cremona on December 16, 1211. He was buried in Cremona.

Writings

Gerardo da Sesso authored a theological summa known by its incipit 'Ne transgrediaris.' This work, written after the pontificate of Urban III, is preserved in two manuscripts and is believed to have been composed during his time at Tiglieto between 1200 and 1205. Its authorship is attributed to 'Gerardus Novariensis' (Gerard of Novara) in later catalogues.
