    Foire aux questions

    The Erdini were an ancient tribe located in the northwest of Ireland, specifically around the area of Donegal Bay. They represent the raw, tribal bedrock of the Irish Iron Age, existing in a period of protohistory where the island's wild edges first began to be documented by Mediterranean cultures. Unlike the well-known High Kings or the Uí Néill dynasties, the Erdini are considered a 'missing piece' of the Irish puzzle, known primarily through ancient geographical records.

    Knowledge of the Erdini comes largely from a second-century geography book written by Ptolemy, a mathematician in Egypt who mapped the world's coordinates without ever visiting Ireland. His work serves as a vital link between Roman explorers and the unmapped edges of the Atlantic. This single entry has triggered centuries of detective work, connecting Greek scholarship and ancient manuscripts to the physical landscape of the Irish coast and medieval myth-making.

    The Erdini inhabited the cliffs and river mouths of Donegal Bay roughly eighteen hundred years ago. This location is significant because it places them at the very edge of the known world during the Iron Age. By studying their presence in this specific region, historians can better understand the transition from prehistoric tribal life to the documented history of Ireland, bridging the gap between ancient Mediterranean observations and the heritage of the Irish landscape.
