Parents can make Halloween an educational as well as fun affair by introducing children to some of the historical traditions of Halloween, according to a Hamilton College medieval historian. Hans Broedel, visiting assistant professor of history at Hamilton College, explains that Halloween is rooted in Celtic tradition. Although many misconceptions about medieval spiritual life are rampant today, some Celtic Halloween practices have been preserved, such as making jack-o'-lanterns, although with a bit of a twist. They used turnips instead of pumpkins... So teach children a little history lesson and preserve Halloween fun at the same time: try a turnip-carving session," Broedel says.
