My father is spending this Friday the 13th taking his two daughters to watch the England women’s football team take on their American counterparts at Stadium MK. And while, yes, I know about those 13 superstitions – Judas was the 13th guest at the last supper, there were 13 steps to the gallows, it’s the crap roll in a baker’s dozen – but haven’t we moved on from fearing that a group of 13 women is in fact a coven? The Anglo Saxon goddess of fecundity shares the rest of the working week with a veritable sausage fest of gods: Thor, Woden and Tyr. Friday is the only day in the British week named after a woman – Freyja.
