I like Martin Luther’s polemic about relics: “How many pieces of the true cross are there in the world? How many thorns from Christ’s crown of thorns? How many nails from the crucifixion? There are enough nails to shoe all the horses in Saxony. And if all the relics of the saints were gathered together, there would be enough bones to build a ship and enough wood to boil all the water in the sea.”
In that sense it’s one of Mary Magdalene’s many heads.
