And talking of miracles…
Thomas Aquinas was a noted theologian, best known for his Summa Theologica which contained multiple cast-iron (to him) proofs of the existence of god.
When he died, the Catholic church was keen to canonise him. But there are two main prerequisites for making someone a saint: they either have to have been martyred (undergoing a gruesome death for the church), or they have to have performed a miracle.
Aquinas had led a peaceful, harmonious life, dying comfortably in bed. But when the church looked into whether he had performed any miracles, they came up short. Until they discovered the Miracle of the Herring.
On his deathbed, so the story goes, Aquinas was asked if he needed anything. He replied that he could really fancy a herring, to remind him of his youth.
This posed a problem, as his deathbed was in Italy, where no herrings were to be found. So his attendants gave him a sardine instead.
On eating it, Aquinas pronounced that this was the best herring he had ever tasted. The sardine had turned into a herring in his mouth – and that, faithful followers, was the miracle.
