Samhain is upon us. Halloween. The Day of the Dead. All Saints’ Day. All Souls’ Day. That liminal time of year when the doorways to what the Celts called the Otherworld, Annwn in Welsh, are open. In New York City, we have the 45th annual Village Halloween Parade, a queer extravaganza of puppetry, masquerade, and cross-dressing that draws some 60,000 participants and over 2 million onlookers. Elsewhere, we have children in costume and lawns covered with plastic skeletons and illuminated ghouls. Everywhere, if we’re lucky, we might catch a glimpse of  “the piper at the gates of dawn,” the vision granted Rat and Mole in Kenneth Grahame’s The Wind in the Willows: “something very surprising and splendid and beautiful”—Pan the goat-god, boundary-crosser, Friend and Helper, trans-being.
