Question: What is the myth behind gnomes? Why do people place them in their yards and gardens? Please let me know in   very deep details! I'm doing this for a story called "The Stone"

Answer: Gnome\nA Gnome is a mythical creature characterized by its small stature and subterranean lifestyle. According to Paracelsus, gnomes are the most important of the elemental spirits of the classical element earth, and they move as easily through the earth as humans walk upon it. The sun's rays turn them into stone. In other traditions, they are simply small, mischievous sprites or goblins. Some sources claim they spend the daytime as toads instead of in stone.\n\nOften featured in Germanic fairy tales, including those by the Brothers Grimm, the gnome often resembles a gnarled old man living deep underground and guards buried treasure. Because of this, Swiss bankers are sometimes disparagingly referred to as the Gnomes of Zürich. Gnomes feature in the legends of many of central, northern and eastern European lands by other names: a kaukis is a Prussian gnome, and barbegazi are gnome-like creatures with big feet in the traditions of France and Switzerland. In Iceland, gnomes (vættir) are so respected that roads are re-routed around areas said to be inhabited by them. Further east, tengu are sometimes referred to as winged gnomes.\n\nIndividual gnomes are not very often detailed or featured as characters in stories, but in Germanic folklore, Rübezahl, lord over the underworld, was sometimes referred to as a mountain gnome. According to some traditions, the gnome king is called Gob.\n\nRudolf Steiner, and other theosophists before him, lectured at length on gnomes, and especially their supportive role in the development of plant life (and biodynamic agriculture). Rupert Sheldrake has written a good deal about morphogenic fields, an idea Terry Pratchett used in his Discworld books many times.\n\nThe word gnome is said to derive from the New Latin gnomus and ultimately from the Greek gnosis, meaning knowledge. According to myth, gnomes hoarded secret knowledge just as they hoarded treasure.\n\nGarden gnomes\n\nThe first garden gnomes were introduced to the United Kingdom in 1847 by Sir Charles Isham, when he brought 21 terracotta figures back from a trip to Germany and placed them as ornaments in the gardens of his home, Lamport Hall in Northamptonshire. Only one of the original batch of gnomes survives: Lampy as he is known, is on display at Lamport Hall, and is insured for one million pounds.\n\nGarden gnomes have become a popular accessory in many gardens, although they are not loved by all. They are often the target of pranks: people have been known to return garden gnomes "to the wild", most notably France's "Front de Liberation des Nains de Jardins" and Italy's "MALAG" (Garden Gnome Liberation Front). Some kidnapped garden gnomes have been sent on trips around the world (the travelling gnome prank).\n\nA sub-culture exists among those who collect garden gnomes, which is frequently lampooned in popular culture.\n\nGarden gnomes were made in various poses and pursuing various pastimes, such as fishing or gardening. More recently, garden gnomes have been depicted indulging in indecent exposure or having sex.\n\n\n\nGnomic Culture\n\n    * The Nome King (spelled without the silent "G") and his nome subjects nearly transformed Dorothy Gale and her friends into bric-a-brac in Ozma of Oz, the third book in L. Frank Baum's The Wonderful Wizard of Oz series. The character appeared several times in later books in the series.\n\n    * J. R. R. Tolkien used the word gnome in his early work The Book of Lost Tales for a fictional people later called Ñoldor. He dropped the term in his published works, since he found the gnomes of folklore to be so unlike his High Elves as to confuse his readers. "Gnomes" also refer to the Valar.\n\n    * Gnomes are one of several races on Terry Pratchett's Discworld, where they are also called goblins. The Nac Mac Feegle are sometimes considered an ethnic subgroup of gnomes.\n\n    * Nomes (again without a "G") are a race of t
