jack o' lanterns...

Why do we carve and display the jack o' lantern at Halloween?

It's an Irish story of an endless journey between two worlds...https://t.co/TMbxe3XNxp via @IcySedgwick

Inreresting from the above source - Vegetable and fruit carving is an old tradition and exists across the world. Gourds were the first plant that was domesticated for its carving potential some 10,000 years ago, and among other things, they were also carved to serve as lanterns. The Maori were the first people to carve gourds into lanterns 700 years ago.
