Empires may fall, civilisations crumble and religions fade into legend but human fragility in the face of elemental forces remains.
Since the dawn of time - eons before insurance, smoke alarms and health and safety regulations were invented - seasonal rituals have been practised as symbolic protection from outrageous fortune.
Long before Guy Fawkes was commemorated on November 5 - by order of the English King James I as a warning to any who might consider any copycat attempts to blow up the House of Lords, as Fawkes allegedly did in 1605 - and way before Halloween evolved out of the Christian calendar, hilltop bonfires were lit on the pagan/Celtic northern hemisphere autumn festival of Samhain at the beginning of November to frighten away the black chaos of winter with a defiant show of light.
Of course, holding an autumn festival here in spring makes no sense. Neither does the spring festival of Easter in autumn and snowy Christmas in sticky summer, but we do our best to adapt the trappings of colonial hangovers.
After Christianity took root, Christmas and Easter too were expediently grafted on to pre-existing ritual observances.
