250 BCE.[23] Prakrit records predominate the epigraphic records discovered in the Indian subcontinent through about the 1st century CE.[23] The earliest known Brahmi inscriptions in Sanskrit are from the 1st century BCE, such as the few discovered in Ayodhya, Ghosundi and Hathibada (both near Chittorgarh).[24][note 1] Ancient inscriptions have also been discovered in many North and Central Indian sites, occasionally in South India as well, that are in hybrid Sanskrit-Prakrit language called "Epigraphical Hybrid Sanskrit".[note 2] These are dated by modern techniques to between the 1st and 4th centuries CE.[27][28] Surviving ancient records of the Brahmi script are found as engravings on pillars, temple walls, metal plates, terracotta, coins, crystals and manuscripts.[29][28]
