Data Visualizations

Exploring Celtic Civilizations uses data abouty material artifacts, people, events and source texts to aid in discussing and exploring the history of Celtic-speaking communities across space and time. Explanations of the definitions of data records is offered below. All visualizations are powered by the Prospect data collaboratory.
