...the time, according to folklore and myth, when the borders between the worlds grow thin, transparent, and permeable; when the dead return, and faeries ride the hills, and the twilight shimmers with ancestral magic.
The tradition of pumpkin carving began not with carving pumpkins, but carving potatoes, turnips, and beets. The Irish would carve faces into these in the hope of warding away evil spirits that roamed the land on Samhain. This idea came from the story of Jack of the Lantern (Stingy Jack). When the Irish came to America, they used pumpkins, which were native and much easier to carve.
