Brother (Christian) in the context of Fraternities

A friar is a member of one of the mendicant orders in the Catholic Church. There are also friars outside of the Catholic Church, such as within the Evangelical-Lutheran Churches and Anglican Communion. The term, first used in the 12th or 13th century, distinguishes the mendicants' itinerant apostolic character, exercised broadly under the jurisdiction of a superior general, from the older monastic orders' allegiance to a single monastery formalized by their vow of stability. A friar may be in holy orders or be a non-ordained brother. The most significant orders of friars are the Dominicans, Franciscans, Augustinians, and Carmelites.

A fraternity (from Latin frater 'brother' and -ity; whence, "brotherhood") or fraternal organization is an organization, society, club or fraternal order traditionally of men but also women associated together for various religious or secular aims. Fraternity in the Western concept developed in the Christian context, notably with the religious orders in the Catholic Church during the Middle Ages. The concept was eventually further extended with medieval confraternities and guilds. In the early modern era, these were followed by fraternal orders such as Freemasons, the Rosicrucian Society of England, and Odd Fellows, along with gentlemen's clubs, student fraternities, and fraternal service organizations. Members are occasionally referred to as a brother or – usually in a religious context – frater or friar.

Today, connotations of fraternities vary according to context including companionships and brotherhoods dedicated to the religious, i.e., (Knights of Columbus), intellectual, academic, physical, or social pursuits of its members. In modern times, it sometimes connotes a secret society especially regarding Freemasonry, Odd Fellows, various academic, and student societies.

Andrea Pozzo (Italian: [anˈdrɛːa ˈpottso]; Latinized version: Andreas Puteus; 30 November 1642 – 31 August 1709) was an Italian Jesuit brother, Baroque painter, architect, decorator, stage designer, and art theoretician.

Pozzo was best known for his grandiose frescoes using the technique of quadratura to create an illusion of three-dimensional space on flat surfaces. His masterpiece is the nave ceiling of the Church of Sant'Ignazio in Rome. Through his techniques, he became one of the most noteworthy figures of the Baroque period. He is also noted for the architectural plans of Ljubljana Cathedral (1700), inspired by the designs of the Jesuit churches Il Gesù and S. Ignazio in Rome.
