Celtica

Celtica evokes the Celtic-speaking peoples of Ireland, Scotland, Wales and Brittany, whose languages belong to the Gaelic and Brittonic branches. In 1707 the Welsh scholar Edward Lhuyd published a study of the languages and histories of Britain's early inhabitants, helping popularize their shared Celtic connections.
