Cardinal (Catholic) in the context of "Galero"

A hierarchical organization or hierarchical organisation (see spelling differences) is an organizational structure where every entity in the organization, except one, is subordinate to a single other entity. This arrangement is a form of hierarchy. In an organization, this hierarchy usually consists of a singular/group of power at the top with subsequent levels of power beneath them. This is the dominant mode of organization among large organizations; most corporations, governments, criminal enterprises, and organized religions are hierarchical organizations with different levels of management power or authority. For example, the broad, top-level overview of the hierarchy of the Catholic Church consists of the Pope, then the Cardinals, then the Archbishops, and so on. Another example is the hierarchy between the four castes in the Hindu caste system, which arises from the religious belief "that each is derived from a different part of the creator God’s (Brahma) body, descending from the head downwards."

Members of hierarchical organizational structures mainly communicate with their immediate superior and their immediate subordinates. Structuring organizations in this way is useful, partly because it reduces the communication overhead costs by limiting information flows.

Niccolò Albergati (1373 – 9 May 1443) was an Italian Carthusian and a prelate of the Roman Catholic Church. He was appointed cardinal and served as a papal diplomat to France and England (1422–23) in addition to serving as the bishop of Bologna from 1417 until his death.

He accepted the position as bishop in obedience despite his extreme reluctance to accept the position but carried out his duties with care and attention to educational concerns. But two conflicts in his see caused him to depart and later return and he became known for being close to Pope Martin V and his successor Pope Eugene IV. Both men held Albergati in high esteem and nominated him to crucial positions within the Roman Curia and the diplomatic service to oversee important missions. He had prominent roles in the Council of Basel-Ferrara-Florence and also attended the Council of Florence.

Giovanni Visconti (1290–1354) was an Italian Roman Catholic cardinal, who was co-ruler in Milan and lord of other Italian cities. He also was a military leader who fought against Florence, and used force to capture and hold other cities.

The Basilica of Santa Aurea is a church situated in the Ostia Antica district of Ostia, Italy. Ostia became an episcopal see as early as the 3rd century AD. The present-day church, completed in 1483, is the cathedral of the suburbicarian diocese of Ostia.

Thomas of Capua (Italian: Tommaso da Capua, Latin: Thomas Capuanus), also called Tommaso di Eboli (before 1185 – August 1239), was an Italian prelate and diplomat. He served as the archbishop-elect of Naples from 1215 until 1216 and then as a cardinal until his death. He administered the diocese of Albano between 1218 and 1222 and was the papal legate in the kingdom of Italy from November 1236 until October 1237. He was the most important of Pope Gregory IX's negotiators with the Emperor Frederick II between 1227 and 1237.

Thomas was a notary and a longtime official of the apostolic chancery and apostolic penitentiary. He wrote poetry and style guides in Latin, and 700 of his letters have been preserved. He was an early supporter of the mendicant orders.
