St. Ia was a 5th century Irish princess who, after being converted to Christianity, decided that it was her duty to join a missionary party that was planning to cross the Celtic Sea in order to convert the good people of Cerniw.
The story goes that the boat left without her, but undeterred, she set about making her own arrangements – so what did she do? she sailed over on a leaf of course! Now, I have to admit I am partaking in a glass of fruit cider while I’m writing this, but I can assure you that the story is true, it must be, I’ve read the same story from several different sources just to confirm that I haven’t been hallucinating.
Call me an old cynic if you like, but I don’t believe a word of it. Having said that, it seems pretty likely that the Irish princess did make it across to the shores of Cornwall one way or another, and it also seems likely that she landed at Pendinas, or ‘The Island’ as it’s called today.
