Mangulam inscriptions

Mangulam inscriptions were discovered by Robert Sewell in the caves of the hill in 1882.^[6] This was the earliest finding of such kind of inscriptions. In 1906, Indian epigraphist V. Venkayya tried to read the inscriptions and found that it similar to the Brahmi script in Ashokan edicts, he thought that the inscriptions were in Pali language.^[7][8] In 1919, epigraphist H. Krishna Sastri identified few Tamil words in the inscriptions.^[8] In 1924, K. V. Subrahmanya Aiyar discovered that inscriptions are in Tamil with some Prakrit loan words in the Brahmi script and concluded that script is Tamil-Brahmi.^[6] In 1965, Iravatham Mahadevan recorded the inscriptions in the caves^[2] and dated it to the late 3rd century BCE.^[9][10]

There are five caves in the hill of which six inscriptions are found in four caves.^[6] These were inscribed during Sangam period, hence it is considered one of the important inscriptions in Tamil Nadu.^[11] Archeologists found sherds, sling stones^[1] and an ancient burial site^[12] during the excavation in the region. In 2007, Tamil Nadu Archaeology Department excavated the ruins of the Jain prayer halls of Sangam period.^[6] The inscriptions are among the protected monuments in Tamil Nadu by the Archaeological Survey of India.^[13]
