The study of history of Celts including disciplines such as paleolinguistics, ancient history, and history of Celtic art, anthropology, religious history, mythology, ethnology and folklore have been taking place in the last two decades.

Literary reference about the Celtic people was made by Hecataeus, a Greek historian in the 517 BC. The tribe of Keltoi – that’s how the ancient Greeks refer the Celts – is located in Rhenania (present day West and Southwest Germany). The primogenitor of Celts is Celtus who is the son of Heracles and Keltine according to Greek mythology. Ancient Romans used the word “Celtae” to refer to Gauls from the continent.

Celtic myths were written only in the 11th Century AD; these myths are quite ancient and are kept alive by oral tradition. Ireland and Wales are the main sources for the Celtic myths. The legends of King Arthur were originated from Wales and to some extent from Ireland. Brittany is the origin for medieval Romans of Isolde and Tristan which is very popular in British Isles and Continental Europe. As per the Celtic myths the Celts divided their people by social classes and by clans. The nobles such as chiefs and kings are high among the social classes. They are a part of the warrior societies. The aristocrats dominated the warriors. Bards and druids are some of the other classes who were highly regarded for their knowledge.
