Question: Who wrote the letters that stated Nubian fighting men were sought after by kingdoms in Southwest Asia? Passage 1:The Italian is a 1915 American silent film feature which tells the story of an Italian gondolier who comes to the United States to make his fortune but instead winds up working as a shoeshiner and experiencing tragedy while living with his wife and child in a tenement on New York's Lower East Side. The film was produced by Thomas H. Ince, directed by Reginald Barker, and co-written by C. Gardner Sullivan and Ince. The film stars stage actor George Beban in the title role as the Italian immigrant, Pietro "Beppo" Donnetti. In 1991, this film was deemed "culturally, historically, or aesthetically significant" by the United States Library of Congress and selected for preservation in the National Film Registry.
Passage 2:Methodios Fouyias (; 12 September 1924 in Corinth 7 July 2006) served as Greek Orthodox Archbishop of Thyateira and Great Britain (concomitantly apokrisiarios of the Ecumenical Patriarch to the Archbishop of Canterbury) from 1979 to 1988. After studies in the Theological Faculty of the University of Athens and parochial responsibilities in Munich, he served in various positions within the Patriarchate of Alexandria culminating in that of Metropolitan of Axum covering Ethiopia and the Horn of Africa. Fouiyas' studies and encounters led to a favourable understanding of the Church of England which he saw in some respects as a continuator of the Saxon Church before the Norman Conquest, the Gregorian Reform and most importantly the EastWest Schism of 1054. He was thus seen as the ideal candidate for the post of archbishop in London. Several years experience however of deepening division within Anglicanism led him openly to suggest (in an article in The Times) that the road to unity for Anglicans lay in submission to the discipline of the Roman Catholic church. As his post involved close relations with Lambeth it was judged expedient that he should be recalled. Methodios assumed the title of Pisidia and continued his studies (notably on Bessarion) in Greece.
Passage 3:During the Middle Kingdom military sophistication and strength continued to expand. Well-organized expeditions into Nubia were conducted, and a number of fortresses were built to control Nubian territory, such as the works at Buhen. Deep ditches surrounded some of these fortifications, with walls up to 24 feet thick, creating strong bases against rebellion or invasion. Recruiting quotas were assigned on a regional basis and designated scribes drafted soldiers as needed for the armies of the state. Striking forces were still primarily infantry-based, and tactics did not change drastically from previous eras. A key role in the strengthening of Egyptian forces was played by infantrymen from Nubia, both as spearmen and archers. Parts of Nubia were renowned for such fighting men, and indeed a part of the Nubian territory was called Ta-Seti or Land of the Bow by the Egyptians. The Egyptians and Nubians were ethnically the closest in the region, frequently exchanging people, genes, resources and culture over several centuries, and occasionally engaging one another in military conflict. Nubian fighting men were also sought as mercenaries by various kingdoms of Southwest Asia, according to the Amarna letters.
