A gnome is a mythological creature and diminutive spirit in Renaissance magic and alchemy, introduced by Paracelsus in the 16th century and widely adopted by authors including those of modern fantasy literature. Typically small humanoids who live underground, gnome characteristics are reinterpreted to suit various storytellers and artists.

Renaissance magic was a resurgence in Hermeticism and Neo-Platonic varieties of the magical arts which arose along with Renaissance humanism in the 15th and 16th centuries CE. During the Renaissance period, magic and occult practices underwent significant changes that reflected shifts in cultural, intellectual, and religious perspectives. C. S. Lewis, in his work on English literature, highlighted the transformation in how magic was perceived and portrayed. In medieval stories, magic had a fantastical and fairy-like quality, while in the Renaissance, it became more complex and tied to the idea of hidden knowledge that could be explored through books and rituals. This change is evident in the works of authors like Spenser, Marlowe, Chapman, and Shakespeare, who treated magic as a serious and potentially dangerous pursuit.
