Guinean writer Djibril Niane suggests in ''Sundiata: An Epic of Old Mali'' (1965) that it is not impossible that Mali was the name given to one of the capitals of the emperors. 14th-century Moroccan traveler Ibn Battuta reported that the capital of the Mali Empire was called Mali. One Mandinka tradition tells that the legendary first emperor Sundiata Keita changed himself into a hippopotamus upon his death in the Sankarani River and that it's possible to find villages in the area of this river, termed "old Mali", which have Mali for a name. A study of Malian proverbs noted that in old Mali, there is a village called Malikoma, which means "New Mali", and that ''Mali'' could have formerly been the name of a city.
