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, 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.

Other rituals were more competitive. At some Halloween parties, the first guest to find a burr on a chestnut-hunt would be the first to marry. At others, the first successful apple-bobber would be the first down the aisle.

Of course, whether we’re asking for romantic advice or trying to avoid seven years of bad luck, each one of these Halloween superstitions relies on the goodwill of the very same “spirits” whose presence the early Celts felt so keenly.
