But the 10th century Sanskrit dramatist Rajashekhara does not abide by this rule. Markandeya, as well as later scholars such as Sten Konow, find faults with the Prakrit portions of Rajashekhara's writings, but it is not clear if the rule enunciated by Vishvanatha existed during Rajashekhara's time. Rajashekhara himself imagines Prakrit as a single language or a single kind of language, alongside Sanskrit, Apabhramsha, and Paishachi.[14]
