The last night of October, the Manx new year. The night the dead walked abroad. Bonfires burned on the hilltops. A calf was sacrificed. Offerings were left at the threshold. Children carry carved turnips and sing the Hop-tu-Naa song door to door, one of the oldest surviving Celtic calendar customs in the British Isles. The tradition predates Christianity but was never suppressed by the Manx church, which understood that the calendar of the older world and the calendar of the Christian year could coexist without contradiction. Hop-tu-Naa required no permission, no funding, no legislation. It required only that people remember it and continue to do it.
