But then again, getting to the bottom of the relationship between pumpkins (and other carved vegetables) and Halloween isn't as simple as you might imagine. Reaching for my copy of Ronald Hutton's ever-fascinating The Stations of the Sun: A History of the Ritual Year in Britain, I find the following: "The traditional illumination for guisers or pranksters abroad on [Halloween] night in some places was provided by turnips or mangel wurzels, hollowed out to act as lanterns and often carved with grotesque faces to represent spirits or goblins. They were common in Ireland [...] in the late nineteenth century [...] In eastern England they became generally known as Jack o'Lanterns [...] It is striking, however, that they are so little mentioned in English folklore collections before 1900." Even the exact significance of the carved vegetable, and the light within it, is uncertain. Hutton does suggest, though, that the development of the place of the Jack o'Lantern in American culture in the nineteenth century might be traced to "large-scale Irish immigration in the USA [...] bringing an intensive observation of the festival with it" - carved vegetables and all.
Which brings us to John Greenleaf Whittier, and his tribute to "The Pumpkin" - first published in the Boston Chronotype in 1846, and available in his 1849 Poems here. But there are complications to be found here, too. As you'll see, Whittier's evocation of the iconic squash only makes specific mention of its relationship, in the form of pie, to "Thanksgiving Day". And yet, the following stanza pays tribute to the "fruit loved of boyhood" in terms that unmistakably evoke Halloween:
More food for thought: Nathaniel Hawthorne also uses the image in "The Great Carbuncle", a story from his 1837 collection Twice-Told Tales:
Rob Velella highlights on the American Literary Blog, one of Whittier's greatest inspirations was Robert Burns. So there's a Halloween lineage...
