 In the 12th-14th century period the works of Ramai Pundit ("Sunya Puran"), Boru Chandidas ("Krishna Kirtan"), Sukur Mamud ("Gopichandrar Gan"), Durllava Mullik ("Gobindachandrar Git") and Bhavani Das ("Mainamatir Gan") bear strong grammatical relationship to Assamese; and their expressions and their use of "adi-rasa" are found in the later Panchali works of Mankar and Pitambar.These works are claimed as examples of Bengali literature as well.After this period of shared legacy, a fully differentiated Assamese literature finally emerged in the 14th century.
