  China
  China (ⁱ/ˈtʃaɪnə/; Chinese: 中国; pinyin: Zhōngguó; see also Names of China), officially the People's Republic of China (PRC), is the world's most-populous country, with a population of over 1.3 billion. Covering approximately 9.6 million square kilometres, the East Asian state is the world's second-largest country by land area, and the third- or fourth-largest in total area, depending on the definition of total area.
  The People's Republic of China is a single-party state governed by the Communist Party of China. It exercises jurisdiction over 22 provinces, five autonomous regions, four directly controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau). Its capital city is Beijing. The PRC also claims Taiwan—which is controlled by the Republic of China (ROC), a separate political entity—as its 23rd province, a claim controversial due to the complex political status of Taiwan and the unresolved Chinese Civil War. The PRC government denies the legitimacy of the ROC.

  Egypt
  Egypt ⁱ/ˈiːdʒɪpt/ (Arabic: مصر, Miṣr, Egyptian Arabic: [mɑsˤɾ] ; Coptic: Ⲭⲏⲙⲓ, Kīmi ; Sahidic Coptic: ⲕⲏⲙⲉ, Kēme), officially the Arab Republic of Egypt, Arabic:  جمهوريّة مصر العربيّة (help·info), is a country mainly in North Africa, with the Sinai Peninsula forming a land bridge in Southwest Asia. Egypt is thus a transcontinental country, and a major power in Africa, the Mediterranean Basin, the Middle East and the Muslim world. Covering an area of about 1,010,000 square kilometers (390,000 sq mi), Egypt is bordered by the Mediterranean Sea to the north, the Gaza Strip and Israel to the northeast, the Red Sea to the east, Sudan to the south and Libya to the west.
  Egypt is one of the most populous countries in Africa and the Middle East. The great majority of its over 81 million people live near the banks of the Nile River, in an area of about 40,000 square kilometers (15,000 sq mi), where the only arable land is found. The large areas of the Sahara Desert are sparsely inhabited. About half of Egypt's residents live in urban areas, with most spread across the densely populated centres of greater Cairo, Alexandria and other major cities in the Nile Delta.

  Gaston Maspero
  Gaston Camille Charles Maspero (June 23, 1846 – June 30, 1916) was a French Egyptologist.
  Gaston Maspero was born in Paris to parents of Lombard origin. While at school he showed a special taste for history, and by the age of fourteen he was already interested in hieroglyphic writing. It was not until his second year at the École Normale in 1867 that Maspero met fellow Egyptologist Auguste Mariette, who was in Paris as commissioner for the Egyptian section of the Exposition Universelle. Mariette gave him two newly discovered hieroglyphic texts of considerable difficulty to study, and the young self-taught scholar produced translations of them in less than a fortnight, a great feat in those days when Egyptology was still almost in its infancy. The publication of these texts in the same year established his academic reputation.
  A short time was spent in assisting a gentleman in Peru who was seeking to prove an Aryan affinity for the dialects spoken by the Indians of that country to publish his research, but in 1868 Maspero was back in France at more profitable work. In 1869 he became a teacher (répétiteur) of Egyptian language and archeology at the École Pratique des Hautes Études, and in 1874 he was appointed to the chair of Champollion at the Collège de France.

  Iran
  Coordinates: 32°N 53°E / 32°N 53°E / 32; 53
  Iran (ⁱ/ɪˈrɑːn/ or /aɪˈræn/;Persian: ایران‎ [ʔiˈɾɒn] ( listen)), officially the Islamic Republic of Iran (Persian: جمهوری اسلامی ایران‎ Jomhuri-ye Eslāmi-ye Irān), is a country in Southern and Western Asia. The name "Iran", which in Persian means "Land of the Aryans", has been in use natively since the Sassanian era. It came into use internationally in 1935, before which the country was known to the Western world as Persia ( /ˈpɜrʒə/ or /ˈpɜrʃə/). Both "Persia" and "Iran" are used interchangeably in cultural contexts; however, "Iran" is the name used officially in political contexts.
  The 18th-largest country in the world in terms of area at 1,648,195 km² (636,372 sq mi), Iran has a population of around 79 million. It is a country of particular geopolitical significance owing to its location in the Middle East and central Eurasia. Iran is bordered on the north by Armenia, Azerbaijan and Turkmenistan. As Iran is a littoral state of the Caspian Sea, which is an inland sea, Kazakhstan and Russia are also Iran's direct neighbors to the north. Iran is bordered on the east by Afghanistan and Pakistan, on the south by the Persian Gulf and the Gulf of Oman, on the west by Iraq and on the northwest by Turkey. Tehran is the capital, the country's largest city and the political, cultural, commercial and industrial center of the nation. Iran is a regional power, and holds an important position in international energy security and world economy as a result of its large reserves of petroleum and natural gas. Iran has the second largest proven natural gas reserves in the world and the fourth largest proven petroleum reserves.

  Japan
  Japan ⁱ/dʒəˈpæn/ (Japanese: 日本 Nihon or Nippon; formally 日本国  Nippon-koku or Nihon-koku, literally the State of Japan) is an island nation in East Asia. Located in the Pacific Ocean, it lies to the east of the Sea of Japan, China, North Korea, South Korea and Russia, stretching from the Sea of Okhotsk in the north to the East China Sea and Taiwan in the south. The characters that make up Japan's name mean "sun-origin", which is why Japan is sometimes referred to as the "Land of the Rising Sun".
  Japan is an archipelago of 6,852 islands. The four largest islands are Honshū, Hokkaidō, Kyūshū and Shikoku, together accounting for ninety-seven percent of Japan's land area. Japan has the world's tenth-largest population, with over 127 million people. The Greater Tokyo Area, which includes the de facto capital city of Tokyo and several surrounding prefectures, is the largest metropolitan area in the world, with over 30 million residents.
  Archaeological research indicates that people lived in Japan as early as the Upper Paleolithic period. The first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other nations followed by long periods of isolation has characterized Japan's history. In the late 19th and early 20th centuries, victory in the First Sino-Japanese War, the Russo-Japanese War and World War I allowed Japan to expand its empire during a period of increasing militarism. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the atomic bombings of Hiroshima and Nagasaki. Since adopting its revised constitution in 1947, Japan has maintained a unitary constitutional monarchy with an emperor and an elected parliament called the Diet.

  Kerameikos
  Kerameikos (Greek: Κεραμεικός) is an area of Athens, Greece, located to the northwest of the Acropolis, which includes an extensive area both within and outside the ancient city walls, on both sides of the Dipylon (Δίπυλον) Gate and by the banks of the Eridanos River. It was the potters' quarter of the city, from which the English word "ceramic" is derived, and was also the site of an important cemetery and numerous funerary sculptures erected along the road out of the city towards Eleusis.
  The area took its name from the city quarter or dēmos (δῆμος) of the Kerameis (Κεραμεῖς, potters), which in turn derived its name from the word κέραμος (kéramos, "pottery clay", from which the English word "ceramic" is derived). The "Inner Kerameikos" was the former "potters' quarter" within the city and "Outer Kerameikos" covers the cemetery and also the Dēmósion Sēma (δημόσιον σῆμα, public graveyard) just outside the city walls, where Pericles delivered his funeral oration in 431 BC. The cemetery was also where the Ηiera Hodos (the Sacred Way, i.e. the road to Eleusis) began, along which the procession moved for the Eleusinian Mysteries. The quarter was located there because of the abundance of clay mud carried over by the Eridanos River.

• Action Man
  Action Man is an action figure boys' toy launched in Britain in 1966 by Palitoy as a licensed copy of Hasbro's American "moveable fighting man": G.I. Joe.
  Action Man was originally produced and sold in the United Kingdom and Australia by Palitoy Ltd of Coalville, Leicestershire from 1966 until 1984 (Palitoy also offered sub-licenses to various toy manufacturers in various markets).
  The figure and accessories were originally based on the Hasbro (US) 1964 G.I. Joe figure (for 1966–1969 production). Hasbro's G.I. Joe figure was patented in 1966 Even the specific method of attaching the appendages was patented as a "Connection For Use In Toy Figures" The first Action Man figures were Action Soldier, Action Sailor and Action Pilot. All were available in the four original hair colours: Blonde, Auburn, Brown and Black. They were accompanied by outfits depicting United States Forces of WWII and the Korean War. In later years, the figures and accompanying uniforms and accessories would more accurately reflect the forces of the United Kingdom. Action Man was subsequently reintroduced in 1993, based on the G.I. Joe Hall of Fame figure of that time.

  Plato
  Plato ( /ˈpleɪtoʊ/; Greek: Πλάτων, Plátōn, "broad"; 424/423 BC – 348/347 BC) was a Classical Greek philosopher, mathematician, student of Socrates, writer of philosophical dialogues, and founder of the Academy in Athens, the first institution of higher learning in the Western world. Along with his mentor, Socrates, and his student, Aristotle, Plato helped to lay the foundations of Western philosophy and science. In the words of A. N. Whitehead:
  The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato. I do not mean the systematic scheme of thought which scholars have doubtfully extracted from his writings. I allude to the wealth of general ideas scattered through them.
  Plato's sophistication as a writer is evident in his Socratic dialogues; thirty-six dialogues and thirteen letters have been ascribed to him. Plato's writings have been published in several fashions; this has led to several conventions regarding the naming and referencing of Plato's texts. Plato's dialogues have been used to teach a range of subjects, including philosophy, logic, ethics, rhetoric, and mathematics.
