November 11 is the feast of St Martin, or Martinmas. Saint Martin was a bishop of Tours whose shrine became a famous stopping-point for pilgrims on the road to Santiago de Compostela. Around his name much legendary material accrued and he has become one of the most familiar and recognizable Roman Catholic saints. St. Martin's Feast is considered the first day of Winter for practical purposes, so, alluding to the snows of that season, the Germans say that "St Martin comes riding on a white horse." Of course, it might not feel like Winter if one is experiencing a "St. Martin's Summer" -- the equivalent of an "Indian Summer." It is said, too, that one can predict what sort of Winter one will have by the conditions of St. Martin's Day: "If the geese at Martin’s Day stand on ice, they will walk in mud at Christmas."
The Feast coincides not only with the end of the Octave of All Souls, but with harvest time, the time when newly-produced wine is ready for drinking, and the end of winter preparations, including the butchering of animals (an old English saying is "His Martinmas will come as it does to every hog," meaning "he will get his comeuppance" or "everyone must die"). Because of this, St. Martin's Feast is much like the American Thanksgiving (celebrated on the 4th Thursday in November) -- a celebration of the earth's bounty. Because it also comes before the penitential season of Advent, it is seen as a mini "carnivale" with all the feasting and bonfires. As at Michaelmas on 29 September, goose is eaten in most places. The goose is a symbol for St. Martin himself. It is said that as he was hiding from the people who wanted to make him Bishop, a honking goose gave away his hiding spot.
Old superstitious folklore says that if you stand in the back of the church and look out over the congregants on St. Martin's Day, you can see auras of light around the heads of those who will not be among the living at the next Martinmas.
