There is lots of information about how the Giant’s Causeway on the Northern Irish coast was formed by volcanic eruptions more than 60 million years ago. As the surface of the lava flow cooled, it contracted and crystallized into hexagonal columns. As the rock settled and eroded over time, the columns broke off so they now look like steps of various heights.
But the locals know that the Giant’s Causeway was really the home and playground of a giant Ulster warrior named Fionn mac Curnhaill (or in English, Finn MacCool…I kid you not). Finn built a series of stepping-stones all the way to Scotland so he could spy on his rival and fellow giant, Cullihin. When he realized that Cullihin was much larger than him, Finn came running back to his wife – with Cullihin in quick pursuit.
Finn’s wife Oona was the clever one in the relationship. She dressed Finn up as a baby and put him to bed, warning him not to say a word. When Cullihin showed up looking to fight Finn, Oona asked him in for tea. She explained that while Finn has stepped out for a while, perhaps Cullihin would like to see their baby.
Cullihin was amazed at the size of the infant, and decided if the babe was this large, then Finn must be huge. Cullihin made a quick retreat back to Scotland, smashing the stepping stone bridge as he went.
Looking around the causeway, there are all kinds of signs that Finn, Oona, and Finn’s grandmother really existed (and still exist).
