The main source of information about Lalitaditya is "Rajatarangini", a chronicle of the rulers of Kashmir, by the 12th century Kashmiri writer Kalhana. Lalitaditya also finds a brief mention in the New Book of Tang ("Xin Tang shu"), a record of the Tang dynasty of China. This text mentions him as "Mu-to-pi" or "Muduobi" (a variation of Muktapida). The 11th century Persian chronicler Al-Biruni mentions a Kashmiri king called Muttai, who was most probably Lalitaditya ("Muttai" being derived from the Apabhramsha form of "Muktapida").
