From Wikipedia: "In the world map of Diseark (285-347 B.C.) too, Persian Gulf and Arabian Gulf have been clearly distinct. At the same time, many maps and deeds prepared up to the 8th century by the historians such as Arrian, Hecataeus, Herodotus, Hiparek, Claudius Batlamious, Krats Malous,…… and in the Islamic period, Khwārizmī, Abou Yousef Eshagh Kandi, Ibn Khordadbeh, Batani (Harrani), Mas'udi, Balkhi, Estakhri, Ibn Houghal, Aboureyhan Birouni and others, mention that there is a wide sea at south of Iran named “Pars Sea”, “Pars Gulf”, “Fars Sea”, “Fars Gulf”, “Bahre Fars”, “Sinus Persicus” and “Mare Persicum” and so on. In a book, named “Persilus Aryateria”, the Greek traveller of the 1st century A.D. has called the Red Sea as Arabian gulf; the Indian ocean has been named Aryateria Sea; the waters at Oman Coast is called Pars Sea; Barbarus region between Oman and Yemen coast are called belonging to Pars, and the Gulf located at south side of Iran is named: Persian Gulf. By describing the water body, the life of Persians living at both sides have also been confirmed.Most recently, at the Twenty-third session of United Nation in March-April 2006, the name "Persian Gulf" was confirmed again as the legitimate and the official term to be used by members of United Nation."
