Q:Information: - In the burial practices of ancient Rome and Roman funerary art, marble and limestone sarcophagi elaborately carved in relief were characteristic of elite inhumation burials from the 2nd to the 4th centuries AD. At least 10,000 Roman sarcophagi have survived, with fragments possibly representing as many as 20,000. Although mythological scenes have been mostly widely studied, sarcophagus relief has been called the "richest single source of Roman iconography," and may also depict the deceased's occupation or life course, military scenes, and other subject matter. The same workshops produced sarcophagi with Jewish or Christian imagery. Early Christian sarcophagi produced from the late 3rd century onwards, represent the earliest form of large Christian sculpture, and are important for the study of Early Christian art. - The Apostolic Age of the history of Christianity is traditionally regarded as the period of the Twelve Apostles, dating from the Great Commission of the Apostles by the risen Jesus in Jerusalem around 33 AD until the death of the last Apostle, believed to be John the Apostle in Anatolia c. 100. Traditionally, the Apostles are believed to have dispersed from Jerusalem, founding the Apostolic Sees. It holds special significance in Christian tradition as the age of the direct apostles of Jesus Christ. One major primary source for the ""Apostolic Age"" is the Acts of the Apostles, but its historical accuracy is questioned by some and its coverage is partial, focusing especially from onwards on the ministry of Paul (not one of the twelve apostles) and his companions, and ending around 62 AD with Paul preaching in Rome under house arrest. - The First Council of Nicaea was a council of Christian bishops convened in the Bithynian city of Nicaea (now Iznik, Bursa province, Turkey) by the Roman Emperor Constantine I in AD 325. This first ecumenical council was the first effort to attain consensus in the Church through an assembly representing all of Christendom, although previous councils, including the first Church council, the Council of Jerusalem, had met before to settle matters of dispute. It was presided over by Hosius, bishop of Corduba who was in communion with the See of Rome. - Early Christianity is the period of Christianity preceding the First Council of Nicaea in 325. It is typically divided into the Apostolic Age and the Ante-Nicene Period (from the Apostolic Age until Nicea). - Christianity is a monotheistic religion based on the life and teachings of Jesus Christ, who serves as the focal point for the religion. It is the world's largest religion, with over 2.4billion followers, or 33% of the global population, known as Christians. Christians believe that Jesus is the Son of God and the savior of humanity whose coming as the Messiah (the Christ) was prophesied in the Old Testament. - The Ante-Nicene Period (literally meaning "before Nicaea") of the history of early Christianity was the period following the Apostolic Age of the 1st century down to the First Council of Nicaea in 325. This period of Christian history had a significant impact on the unity of doctrine across all Christendom and the spreading of Christianity to a greater area of the world. Those seen as prominent figures of this era, referred to as the Ante-Nicene Fathers or Proto-orthodox Christians, generally agreed on most doctrine while the teachings of those early Christian writers which the general majority considered to be heretical, were rejected. - Funerary art is any work of art forming, or placed in, a repository for the remains of the dead. The term also encompasses cenotaphs ("empty tombs"), tomb-like monuments which do not contain human remains; and communal memorials to the dead (such as war memorials), which may or may not contain human remains. - Early Christians sarcophagi are those Ancient Roman sarcophagi carrying inscriptions or carving relating them to early Christianity . They were produced from the late 3rd century through to the 5th century . They represent the earliest form of large Christian sculpture , and are important for the study of Early Christian art. The production of Roman sarcophagi with carved decoration spread due to the gradual abandonment of the rite of cremation in favour of inhumation over the course of the 2nd century throughout the empire . However , burial in such sarcophagi was expensive and thus reserved for wealthy families . The end of the Christian persecutions desired by Gallienus in 260 began a period of peace for the Christians that lasted until the end of that century and allowed Christianity to spread in the army , in senior administrative posts and even the emperor 's circles . In the second half of the 3rd century , especially due to increased demand from this group of wealthy Christians , the use of sarcophagi spread widely , with plastic treatments following trends in contemporary sculpture . - A sarcophagus (plural, sarcophagi) is a box-like funeral receptacle for a corpse, most commonly carved in stone, and usually displayed above ground, though it may also be buried. The word "sarcophagus" comes from the Greek "sarx" meaning "flesh", and "phagein" meaning "to eat", hence "sarcophagus" means "flesh-eating"; from the phrase "lithos sarkophagos". Since "lithos" is Greek for "stone", "lithos sarcophagos" means, "flesh-eating stone". The word also came to refer to a particular kind of limestone that was thought to decompose the flesh of corpses trapped within it. - Relief, formerly known as Panorama, is a public affairs newsmagazine series in Canada, airing nightly in Ontario on TFO, the Franco-Ontarian public television network.
