The discovery of the causeway has widely been attributed to the Bishop of Londonderry who visited here with a student in 1692 and took awareness of its existence back to the scholars and gentry of Dublin and London. In 1694, at Trinity College, Dublin, Sir Richard Bukeley, presented a paper to the Royal Society which outlined this 'amazing' discovery' and so initiated the debate on how it was formed.
Theories ranged from 'god' to 'a natural occurrence' and also the possibility of it being create by humans with tools, another possibility was the giant Finn MacCool. From the 1700's it became widely known as the 'Eighth Natural Wonder of the World' and visitors began to come in increasing numbers to see the wonderful array of over 40,000 basalt columns.
While the Bishop may have brought knowledge of its existence to a wider world, the first people to discover this natural phenomenon would have been the Hunter and Gatherers who settled in the area known as White Park Bay after the last ice age, some 10,000 years ago.
They would have travelled around the then densely forested north coast by boat and would have almost certainly come across the causeway on their travels. With no knowledge of the greater natural forces, this this would have appeared even more surreal to them than it does to us. To find such a surreal outcrop of rock would have left a lasting impression on these early settlers who lived off the land and sea, they would have surely passed this information on to following generations and from this it is easy to understand how the legend of the giant would have developed. The height of their technology was making flint arrowheads using stone implement, so to find such precise and what looks like cut stones would only re-inforce this concept of giants.
So perhaps we can let the Bishop keep the recognition and attribute the discovery to these early north coast settlers and also the enduring myths and legends that are associated with the area including Finn MacCool.
