The "Old World" (Latin: Mundus vetus) is a term for Afro-Eurasia coined by Europeans after 1493, when they became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia in the Eastern Hemisphere, previously thought of by the Europeans as comprising the entire world, with the "New World", a term for the newly encountered lands of the Western Hemisphere, particularly the Americas.
Arabic is by far the most widely spoken of the Semitic languages with 411 million native speakers of all varieties, and it is the most spoken native language in Africa and West Asia. Other Semitic languages include Amharic (35 million native speakers), Tigrinya (9.9 million speakers), Hebrew (5 million native speakers), Tigre (1 million speakers), and Maltese (570,000 speakers). Arabic, Amharic, Hebrew, Tigrinya, and Maltese are considered national languages with an official status.
The term was originally used in contrast to the other two proposed divisions of mankind based on the story of Noah: Semites and Japhetites. The appellation Hamitic was applied to the Berber, Cushitic, and Egyptian branches of the Afroasiatic language family, which, together with the Semitic branch, was formerly labelled "Hamito-Semitic". Because the three Hamitic branches have not been shown to form an exclusive (monophyletic) phylogenetic unit of their own, separate from other Afroasiatic languages, linguists no longer use the term in this sense. Each of these branches is instead now regarded as an independent subgroup of the larger Afroasiatic family.
In archaeology, the term is sometimes used informally as "a kind of shorthand" for ancient Semitic-speaking peoples. Identification of pro-Caucasian racism has either partially or completely devalued the use of the term as a racial category, with the caveat that an inverse assessment would still be considered scientifically obsolete.
A T and O map or O–T or T–O map (orbis terrarum, orb or circle of the lands; with the letter T inside an O), also known as an Isidoran map, is a type of early world map that represents the Afro-Eurasian landmass as a circle (= O) divided into three parts by a T-shaped combination of the Mediterranean sea, the river Tanais (Don) and the Nile. The origins of this diagram are contested, with some scholars hypothesizing an origin in Roman or late antiquity, while others consider it to have originated in 7th or early-8th century Spain.
The earliest surviving example of a T-O map is found in a late-7th or early-8th century copy of Isidore of Seville's (c. 560–636) De natura rerum, which alongside his Etymologiae (c. 625) are two of the most common texts to be accompanied by such a diagram in the Middle Ages. A later manuscript added the names of Noah's sons (Sem, Iafeth and Cham) for each of the three continents (see Biblical terminology for race). A later variation with more detail is the Beatus map drawn by Beatus of Liébana, an 8th-century Spanish monk, in the prologue to his Commentary on the Apocalypse.
The Mandaeans speak an Eastern Aramaic language known as Mandaic. The name 'Mandaean' comes from the Aramaicmanda, meaning knowledge. Within the Middle East, but outside their community, the Mandaeans are more commonly known as the صُبَّةṢubba (singular: Ṣubbī), or as Sabians (الصابئة, al-Ṣābiʾa). The term Ṣubba is derived from an Aramaic root related to baptism. The term Sabians derives from the mysterious religious group mentioned three times in the Quran. The name of this unidentified group, which is implied in the Quran to belong to the "People of the Book" (ahl al-kitāb), was historically claimed by the Mandaeans as well as by several other religious groups in order to gain legal protection (dhimma) as offered by Islamic law. Occasionally, Mandaeans are also called "Christians of Saint John", in the belief that they were a direct survival of the Baptist's disciples. Further research, however, indicates this to be a misnomer, as Mandaeans consider Jesus to be a false prophet.
The Generations of Noah, also called the Table of Nations or Origines Gentium, is a genealogy of the sons of Noah, according to the Hebrew Bible (Genesis10:9), and their dispersion into many lands after the Flood, focusing on the major known societies. The term 'nations' to describe the descendants is a standard English translation of the Hebrew word "goyim", following the c. 400 CE Latin Vulgate's "nationes", and does not have the same political connotations that the word entails today.
