Bill Shakespeare's Three Weird Sisters and their bubbling brew have been updated to Three Vegan Witches: eye of potato, ear of corn, head of lettuce, heart of cabbage, skin of banana--all doubtlessly to James's distaste
From Shakespeare through W.S. Gilbert to Sylvia Fine and Roald Dahl, witches have been all the rage--along with the occasional warlock--and the plants they used about their professional projects.
"Double, double, toil and trouble" declaim the three witches in Macbeth. "Fire burn and cauldron bubble" they continue in the great Sottish play. King James I of England (and IV of Scotland) won the label of "the wisest fool in Christendom." His interests extending to witches--he even wrote a treatise on them--so Shakespeare gave him witches in Macbeth.
