Muslim who kept a lamp burning there. The St. Thomas Cathedral Basilica, Chennai, Tamil Nadu, India presently located at the tomb was first built in the 16th century by the Portuguese, and rebuilt in the 19th century by the British. St. Thomas Mount has been a revered site by Muslims and Christians since at least the 16th century. Possible visit to China Thomas's alleged visit to China is mentioned in the books and church traditions of Saint Thomas Christians in India who, for a part, claim descent from the early Christians evangelized by Thomas the Apostle in AD 52. For example, it is found in the Malayalam ballad Thomas Ramban Pattu (The Song of the Lord Thomas) with the earliest manuscript being from the 17th century. The sources clearly have Thomas coming to India, then to China, and back to India, where he died. In other attested sources, the tradition of making Thomas the apostle of China is found in the "Law of Christianity" (Fiqh al-naṣrāniyya), a compilation of juridical literature by Ibn al-Ṭayyib (Nestorian theologian and physician who died in 1043 in Baghdad). Later, in the Nomocanon of Abdisho bar Berika (metropolitan of Nisibis and Armenia, died in 1318) and the breviary of the Chaldean Church it is written: In its nascent form, this tradition is found at the earliest in the Zuqnin Chronicle (AD 775) and may have originated in the late Sasanian period. Perhaps it originated as a 3rd-century pseudepigraphon where Thomas would have converted the Magi (in the Gospel of Matthew) to Christianity as they dwelled in the land of Shir (land of Seres, Tarim Basin, near what was the world's easternmost sea for many people in antiquity). Additionally, the testimony of Arnobius of Sicca, active shortly after AD 300, maintains that the Christian message had arrived in India and among the Persians, Medians, and Parthians (along with the Seres). Possible travel into Indonesia According to Kurt E. Koch, Thomas the Apostle possibly traveled into Indonesia via India with Indian traders. Paraguayan legend Ancient oral tradition retained by the Guaraní tribes of Paraguay claims that the Apostle Thomas was in Paraguay and preached to them. Almost 150 years prior to Dobrizhoffer's arrival in Paraguay, another Jesuit Missionary, F.J. Antonio Ruiz de Montoya recollected the same oral traditions from the Paraguayan tribes. He wrote: The sole recorded research done about the subject was during José Gaspar Rodríguez
