Lobu Tua Inscription, also called Barus Inscription, is an inscription written in Tamil language which was discovered in 1873 in the village of Lobu Tua, Andam Dewi district of Central Tapanuli Regency, in North Sumatra Province, Indonesia. This inscription is dated 1010 Saka, or 1088 AD. This inscription was reported in the Madras Epigraphy Report of 1891-1892 by E. Hultzsch, an English epigraphist in India. The inscription mentions the existence of a Tamiltrade union in the Barus region. The tradeunion was named "The Five Hundreds of a Thousand Directions". According to Prof. Y. Subbarayalu from Tamil University, Thanjavur, this trade union's another name was Ayyavole, which also left a Tamil-language inscription in Aceh. In Barus, they bought various commodities from the local population, and the members were collected excise in the form of gold, which was based on the price of the kasturi. The objects of the excise were the ship, the captain, and kevi. According to reports, in the 1900s a Buddha statue in the form of a torso made of red granite was also found in the site, which is now gone. The existence of the statue in Barus raises the suspicion that the Tamil community there was permanent or semi-permanent, therefore it has its own place of worship. Currently 7/8 parts of the inscription are stored in the National Museum of Indonesia and another one eight part is still in Lobu Tua. Beside inscriptions, in Lobu Tua some dry old cylindrical wells were found as well.
