In 1863, Dutch East Indies, a huge boulder of inscribed stone was spotted near Ciampea not far from Buitenzorg (Bogor). The stone inscription was discovered on the river bed of Ciaruteun river, a tributary of Cisadane River. It is today known as the Ciaruteun inscription, dated from the 5th century, written in Vengi letters (used in the Indian Pallava period) and in Sanskrit language. This is the earliest inscription that clearly mentioned the kingdom's name "Tarumanagara". The inscription reports the most famous king of Tarumanagara.
