Calcutta Stone

Calcutta Stone or known in Indonesia as Pucangan Inscription is an ancient Javanese inscription written in Sanskrit and Old Javanese, dated from 1041 CE during the reign of king Airlangga of the Kahuripan kingdom, that explains some events and the royal genealogy of the king. The inscription more or less narrates the life story of King Airlangga, one of the greatest king in Javanese history, also explaining his lineage as the rightful ruler of Java, the successor of King Dharmawangsa of Isyana dynasty. This inscription was known as "Calcutta Stone", because it is stored in Indian Museum, Kolkata (Calcutta), India, from 19th century until today.

The Pucangan inscription is a bilingual inscription, it consists of two different sides inscribed on a single monolith. The front side is written in Old Javanese while the other side is written in Sanskrit. Both inscriptions are written in Kawi script (Ancient Javanese script). The inscription scape is a block with pointy top, on the base of the inscription is adorned with padma (lotus) pedestal. The name Pucangan derived from a word in this inscription. It was the name of a place on the slopes of Mount Penanggungan, today located in Mojokerto Regency, East Java.
