Original Irish Jack-o-Lanterns were truly terrifying and made of turnips
A far cry from the grinning pumpkins of Halloween today, the original Jack-o-Lanterns, named for Jack OLantern of the Irish myth, were actually quite terrifying.
They were carved from turnips or beets rather than festive orange pumpkins, and were intended to ward off unwanted visitors.
Gourds were one of the earliest plant species, domesticated by humans around 10,000 years ago, mostly cultivated for their carving potential for kitchen tools, dishes, musical instruments, toys, furniture and more. Maoris began carving them for lanterns 700 years ago the Maori word for gourd and lampshade are actually the same.
According to Irish folklore, a man called Jack OLantern was sentenced to roam the earth for eternity. A ghostly figure of the night, OLantern walks with a burning coal inside of a carved-out turnip to light his way.
