The patron saint of Cornwall and tin miners, St Piran was born in Ireland, a quite remarkable individual, he is said to have studied in Rome, been made a bishop and raised the dead, this went down well with his countrymen, but slightly less so with the kings who decided to put a stop to his shenanigans by tying him to a millstone and tossing him into the sea during a storm.
The almighty had different ideas tho and calmed the sea and sent this unconventional vessel floating south till it washed up on Perranzabuloe, Pirans first deciples in Cornwall were a badger, a fox, and a bear, he lived for a while as a hermit but his gift with miracles soon came to the attention of the Cornish who gathered around him and founded the abbey of Lanpiran with Piran as the Abbot.
During this time he made a hearth of black local stone, maybe he knew something the locals didnt or maybe it was divine inspiration, but the stone when heated produced a white metal that sat on the top in a cross, and so tin smelting was rediscovered in Cornwall and the flag of St Piran was made.
