Within Southeast Asia a certain amount of borrowing of literary themes has taken place, but not many examples have been studied in detail. A recognized case of such borrowing is the 'Panji' theme, which originated in Java, was popular for a time in the Malay-speaking world, and from there was transmitted to Thailand in a new guise, namely the tale of 'Inao'.
