TEHRAN, Iran Dec 19, 2004 — Iran unveiled a collection of historical maps on Sunday in a bid to prove the legitimacy of calling its neighboring sea the Persian Gulf instead of the "Arabian Gulf" as it also is listed in the new world atlas by National Geographic. Last month, Iran banned the sale of National Geographic Society publications to protest the "Arabian Gulf" inclusion. The issue also has caused widespread protests by intellectuals, historians, students across Iran, formerly Persia.
