House of Mattei

The House of Mattei was one of the most powerful noble families of Rome during the Middle Ages and early modern era, holding high positions in the papal curia and government office. The family amassed significant art collections under art enthusiasts such as Ciriaco Mattei.

The Mattei gave eight Cardinals to the Catholic Church, among them Girolamo Mattei (1586), Gaspare Mattei (1643), Alessandro Mattei (1803), Mario Mattei (1832), Lorenzo Girolamo Mattei (1833) and (as late as 1875) Ruggero Luigi Emidio Antici Mattei. The founder of one powerful branch of the Mattei was Giovanni Giacomo Mattei.

Mattei family lines reportedly went back to an early Roman family, the Papareschi, and their ancestors included Pope Innocent II (1130–1143). In the 1350s the family moved to the Rione Sant Angelo, and they eventually built six residences in the block called the Isola Mattei. The Mattei established themselves in politics and banking and were closely connected to the politics of the Church; later to its military conquests.

Though they lived in the Roman Ghetto, the historic Jewish quarter, they were Roman Catholic. When Pope Paul IV decided to build a wall around the Ghetto in 1555 and imprison the Jewish population, the Mattei were given a key to the gate.

In Rome the Mattei owned five palazzi in the rione, or quarter, of Sant'Angelo (together they formed the so-called "isola dei Mattei": see Palazzo Mattei), and one in Trastevere. Moreover, they owned Villa Celimontana in the rione Celio. The family assumed control over the bridges closest to their ancestral palace during the papal interregnum, levying charges on various types of traffic, including the Jews who lived in the nearby ghetto when burying their dead outside the city.
