Found some nice Halloween history trivia here:

Halloween, celebrated each year on October 31, is a mix of ancient Celtic practices, Catholic  and Roman religious rituals and European folk traditions that blended together over time to create the holiday we know today. Straddling the line between fall and winter, plenty and paucity and life and death, Halloween is a time of celebration and superstition. Halloween has long been thought of as a day when the dead can return to the earth, and ancient Celts would light bonfires and wear costumes to ward off these roaming ghosts. The Celtic holiday of Samhain, the Catholic Hallowmas period of All Saints’ Day and All Souls’ Day and the Roman festival of Feralia all influenced the modern holiday of Halloween. In the 19th century, Halloween began to lose its religious connotation, becoming a more secular community-based children’s holiday.

But what about the Halloween traditions and beliefs that today’s trick-or-treaters have forgotten all about? Many of these obsolete rituals focused on the future instead of the past and the living instead of the dead. In particular, many had to do with helping young women identify their future husbands and reassuring them that they would someday–with luck, by next Halloween!–be married.

In 18th-century Ireland, a matchmaking cook might bury a ring in her mashed potatoes on Halloween night, hoping to bring true love to the diner who found it. In Scotland, fortune-tellers recommended that an eligible young woman name a hazelnut for each of her suitors and then toss the nuts into the fireplace. The nut that burned to ashes rather than popping or exploding, the story went, represented the girl’s future husband. (In some versions of this legend, confusingly, the opposite was true: The nut that burned away symbolized a love that would not last.) Another tale had it that if a young woman ate a sugary concoction made out of walnuts, hazelnuts and nutmeg before bed on Halloween night, she would dream about her future husband. Young women tossed apple-peels over their shoulders, hoping that the peels would fall on the floor in the shape of their future husbands’ initials; tried to learn about their futures by peering at egg yolks floating in a bowl of water; and stood in front of mirrors in darkened rooms, holding candles and looking over their shoulders for their husbands’ faces.

Now before anyone accuses me of ignoring El Dia de los Muertos (the Day of the Dead), that’s November 2nd. It’s especially appropriate for this election year, as that’s the day we’ll observe the passing of the politically dead from the world of governance into the hallowed realm of the private sector.

Guess which ska-leton above is a liberal.

And while everyone is pondering ancient Celtic/Roman/Catholic rituals, are you pondering what I’m pondering? I’m pondering an Overnight Open Thread.
