What is Paic and how does it fit into a larger history of language and literature in pre-modern India? A re-examination of the sources suggests three points: first, that when people first started talking about Paisaci in the mid-first millennium CE, it was not thought to be a language in the same sense that Sanskrit and Prakrit were languages; second, that Paisaci was integrated into Indian classifications of language at a later stage (ninth-tenth centuries), through the related influences of theatrical knowledge (natyasastra) and Prakrit grammar; third, that the Brhatkatha-which has always been imagined to be ground zero for Paisaci-was lost' not just in the weak sense (of a text that is no longer available at a certain time and place) but in a stronger sense (of a text that is fundamentally incompatible with the principles of textuality operative at a certain time and place). I conclude that the term Paisaci is a playful reinterpretation of bhutabhasa, the language of the past', and that the language is a relic of a textual culture that itself became a ghost' with the advent of the Sanskrit cosmopolis around the second century CE.
