It is said that during antiquity, the ruler ordered gold and diamond miners to pan their ores in the city for security and surveillance reasons. Others claim that the name comes from the word "lembang" in Malay. By adding the same prefix, the city's name means "a place where the water leaks". It also means "a place which was constantly inundated by water". It refers to the geographical features of Palembang, which is a wetland. Some say that the name was given by four brothers who survived a shipwreck near Musi River during the Majapahit reign. It is said that on their way to a new colony in eastern Sumatra, when their ship was wrecked, all belongings in the ship sunk into the sea except a broken wooden box which the survivor used as rafts. The rafts were wobbled ("limbang-limbang") by the waves until they drifted ashore to a land which was later named "Palimbang" by them. Palembang also has a special Chinese character rendition like several cities in Indonesia. In Chinese, Palembang is written as 巨港 (). It refers to the city in the past which was once a bustling major port in Southeast Asia. The Kedukan Bukit Inscription, which is dated 682 AD, is the oldest inscription found in Palembang. The inscription tells of a king who acquires magical powers and leads a large military force over water and land, setting out from Tamvan delta, arriving at a place called "Matajap," and (in the interpretation of some scholars) founding the polity of Srivijaya. The "Matajap" of the inscription is believed to be Mukha Upang, a district of Palembang. According to George Coedes, "in the second half of the 9th century Java and Sumatra were united under the rule of a Sailendra reigning in Java...its centre at Palembang." As the capital of the Srivijaya kingdom, this second oldest city in Southeast Asia has been an important trading centre in maritime Southeast Asia for more than a millennium. The kingdom flourished by controlling the international trade through the Strait of Malacca from the seventh to thirteenth century, establishing hegemony over polities in Sumatra and the Malay Peninsula. Sanskrit inscriptions and Chinese travelogues report that the kingdom prospered as an intermediary in the international trade between China and India. Because of the Monsoon, or biannual seasonal wind, after getting to Srivijaya, traders from China or India had to stay there for several months waiting the direction of the wind changes, or had to go back to China or India.
