Information:  - The Akkadian Empire was the first ancient Semitic-speaking empire of Mesopotamia, centered in the city of Akkad and its surrounding region, also called Akkad in ancient Mesopotamia and Accad in the Bible (Genesis 10:10). The empire united all the Akkadian and Sumerian speakers under one rule. The Akkadian Empire controlled Mesopotamia (modern Iraq, Kuwait, northeast Syria and southeast Turkey), the Levant (modern Syria and Lebanon), and eastern and southern parts of Anatolia (modern Turkey) and Iran, sending military expeditions as far south as Dilmun and Magan (modern Bahrain and Oman) in the Arabian Peninsula.  - A physician, medical practitioner, medical doctor or simply doctor is a professional who practises medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients and methods of treatmentknown as specialitiesor they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communitiesknown as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines (such as anatomy and physiology) underlying diseases and their treatmentthe "science" of medicineand also a decent competence in its applied practicethe art or "craft" of medicine.  - Mesopotamia ("[land] between rivers"; from Ancient Armenian  (Mijagetq); "bild ar-rfidayn" "miyn rodn"; "Beth Nahrain" "land of rivers") is a name for the area of the TigrisEuphrates river system, in modern days roughly corresponding to most of Iraq plus Kuwait, the eastern parts of Syria, Southeastern Turkey, and regions along the Turkish-Syrian and IranIraq borders.  - The Tigris is the eastern member of the two great rivers that define Mesopotamia, the other being the Euphrates. The river flows south from the mountains of southeastern Turkey through Iraq and empties itself into the Persian Gulf.  - Sogdianus ( / sdiens / or / sdiens / ) , king of Persia ( 424 -- 423 BC ) . He ruled the Achaemenid Empire for a short time , with little recognition in his kingdom known primarily from the writings of Ctesias . He was reportedly an illegitimate son of Artaxerxes I by his concubine Alogyne of Babylon . The last inscription mentioning Artaxerxes I being alive can be dated to December 24 , 424 BC. His death resulted in at least three of his sons proclaiming themselves Kings . The first was Xerxes II , who was reportedly his only legitimate son by Queen Damaspia and was formerly Crown Prince . He was apparently only recognized in Persia . The second was Sogdianus himself , possibly recognized in Elam . The third was Ochus , son of Artaxerxes I by his concubine Cosmartidene of Babylon and satrap of Hyrcania . Ochus was also married to their common half - sister Parysatis , daughter of Artaxerxes I and his concubine Andia of Babylon . The first inscription of Ochus as Darius II can be dated to January 10 , 423 BC. He seems to have been recognized by Medes , Babylonia and Egypt . This chaotic state of affairs would prove short - lived . Xerxes II only ruled for forty - five days . He was reportedly murdered while drunk by Pharnacyas and Menostanes on Sogdianus ' orders . Sogdianus apparently gained the support of his regions . He reigned for six months and fifteen days before being captured by his half - brother , Ochus , who rebelled against him . Sogdianus was executed by being suffocated in ash because Ochus had promised he would not die by the sword , by poison or by hunger . Ochus became Darius II ; he was the sole ruler of the Persian Empire until 404 BC.  - The Euphrates (Sumerian: : "Buranuna", : "Purattu", : "al-Furt", : "Prt", : "Yeprat", : "Perat", ) is the longest and one of the most historically important rivers of Western Asia. Together with the Tigris, it is one of the two defining rivers of Mesopotamia. Originating in eastern Turkey, the Euphrates flows through Syria and Iraq to join the Tigris in the Shatt al-Arab, which empties into the Persian Gulf.  - Akkadian ("akkadû", ak-ka-du-u; logogram: URI ) is an extinct East Semitic language (part of the greater Afroasiatic language family) that was spoken in ancient Mesopotamia. The earliest attested Semitic language, it used the cuneiform writing system, which was originally used to write the unrelated Ancient Sumerian, a language isolate. The language was named after the city of Akkad, a major centre of Mesopotamian civilization during the Akkadian Empire (ca. 23342154 BC), but the language itself precedes the founding of Akkad by many centuries.  - A historian is a person who researches, studies, and writes about the past, and is regarded as an authority on it. Historians are concerned with the continuous, methodical narrative and research of past events as relating to the human race; as well as the study of all history in time. If the individual is concerned with events preceding written history, the individual is a historian of prehistory. Although "historian" can be used to describe amateur and professional historians alike, it is reserved more recently for those who have acquired graduate degrees in the discipline. Some historians, though, are recognized by publications or training and experience. "Historian" became a professional occupation in the late nineteenth century as research universities were emerging in Germany and elsewhere.  - Babylon (or ; Aramaic: , "Babel", , "Bavel", , "Bbil") was a major city of ancient Mesopotamia in the fertile plain between the Tigris and Euphrates rivers. The city was built upon the Euphrates and divided in equal parts along its left and right banks, with steep embankments to contain the river's seasonal floods. Babylon was originally a small Semitic Akkadian city dating from the period of the Akkadian Empire c. 2300 BC.  - Ctesias ("Ktsís"), also known as Ctesias the Cnidian or Ctesias of Cnidus, was a Greek physician and historian from the town of Cnidus in Caria. Ctesias, who lived in the 5th century BC, was physician to Artaxerxes Mnemon, whom he accompanied in 401 BC on his expedition against his brother Cyrus the Younger.
