Question: Which William Shakespeare's play has reference to the Fairy Queen from folklore who was believed to rule the fairies?
Context: Titania is a character in [[William Shakespeare]]'s play "[[A Midsummer Night's Dream]]".  In the play, she is the [[Fairy Queen|queen of the fairies]].  Due to Shakespeare's influence, later fiction has often used the name "Titania" for fairy queen characters. According to folklore a fairy path (or 'passage', 'avenue', or 'pass') is a route taken by fairies usually in a straight line and between sites of traditional significance, such as fairy forts or raths (a class of circular earthwork dating from the Iron Age), "airy" (eerie) mountains and hills, thorn bushes, springs, lakes, rock outcrops, and Stone Age monuments.  Ley lines and spirit paths, such as with corpse roads, have some similarities with these fairy paths.  A fairy ring is also a path used by fairies, but in a circle, for dancing, as described by poet W. B. Yeats, "...the fairies dance in a place apart, Shaking their milk-white feet in a ring..." The concept is usually associated with Celtic folklore, especially that of Ireland. The Fairy Queen, in English folklore, traditionally ruled the fairies.  "Fairy Queen" may alternatively refer to: The Quarrel of Oberon and Titania is an oil on canvas painting by the Scottish artist Sir Joseph Noel Paton.  Painted in 1849, it depicts the scene from William Shakespeare's comedy play "A Midsummer Night's Dream", when the fairy queen Titania and fairy king Oberon quarrel; Oberon was considered the King of the fairies in medieval and Renaissance literature.  When exhibited in Edinburgh during 1850, it was declared as the "painting of the season".  It was acquired by the National Galleries of Scotland in 1897, having initially been bought by the Royal Association for Promoting the Fine Arts in Scotland during 1850.  An earlier version of this painting was Paton's diploma picture, which was submitted to the Royal Scottish Academy in 1846; the sum of £700 was paid for it. Queen Mab (pronunciation: "M/ă/v") is a fairy referred to in William Shakespeare's play "Romeo and Juliet", where "she is the fairies' midwife."  Later, she appears in other poetry and literature, and in various guises in drama and cinema.  In the play, her activity is described in a famous speech by Mercutio written originally in prose and often adapted into iambic pentameter, in which she is described as a miniature creature who performs midnight pranks upon sleepers.  Being driven by a team of atomies, she rides her chariot over their noses and "delivers the fancies of sleeping men."  Additionally, while driving "O'er ladies' lips, who straight on kisses dream," she was known to change her mind and instead "plague" "ladies' lips" "with blisters" if she smelled "sweetmeats" or candied fruit eaten to sweeten their breath.  Along with this interpretation, others believe the blisters were a reference to the plague or to herpes simplex.  She is also described as a midwife to help sleepers 'give birth' to their dreams.  She may be a figure borrowed from folklore, and though she is often associated with the Irish Medb in popular culture, and has been suggested by historian Thomas Keightley to be from "Habundia", a more likely origin for her name would be from Mabel and the Middle English derivative "Mabily" (as used by Chaucer) all from the Latin "amabilis" ("lovable"). The Fairy Queen, also known as the East Indian Railway 22 class is a 1855-built steam locomotive, restored and housed at 1893-built Rewari Railway Heritage Museum, plying between the Indian capital of New Delhi and Alwar, in Rajasthan.  Built in 1855, it was certified by the "Guinness Book of Records" in 1998 as being the world's oldest one in regular operation after being restored to haul a luxury train in order to boost tourism in Rajasthan.  The "Fairy Queen" runs on the same basis as the "Palace on Wheels", the tourist train launched in 1982, and in 1999 was awarded a National Tourism Award. Mab ( ), or Uranus XXVI (26), is an inner satellite of Uranus.  It was discovered by Mark R. Showalter and Jack J. Lissauer in 2003 using the Hubble Space Telescope.  It was named after Queen Mab, a fairy queen from English folklore who is mentioned in William Shakespeare's play "Romeo and Juliet". The Fairy Queen or Queen of the Fairies was a figure from folklore who was believed to rule the fairies.  Based on Shakespeare's influence, in English-speaking cultures she is often named Titania or Mab. Mary Hannah Gray Clarke (pen name Nina Gray Clarke; March 28, 1835 - May 30, 1892) was an American author, correspondent, and poet from Rhode Island.  She wrote extensively for magazines and for the public press, and was also the author of many dramas, lyric poems, operettas, stories for the young, and essays.  In addition to the operettas, "Just Like Cinderella" and "Jack Frost's Visit to the Fairies", her works included "Effle, Fairy Queen of Dolls," "Prince Pussin-Boots," "Golden Hair and her Knight of the Beanstalk in the Enchanted Forest," "Obed Owler and the Prize Writers," "How I Came to Leave Town and What Came of It," "Edith Morton, the Sensible Young Lady;" "The Story that the Willow Basket Told to Faith Fairchild;" "English Lyrics;" and "Home;" as well as a number of songs, such as "Were it not for Dreams;" ; "Twittering Swallow;" "Robin, Robin, Bold and Free;" "Down by the River;" "Not to Blame;" and "Our-Leafed Clover." A Midsummer Night's Dream is a 1935 American romance fantasy film of William Shakespeare's play, directed by Max Reinhardt and William Dieterle, and starring James Cagney, Mickey Rooney, Olivia de Havilland, Jean Muir, Joe E. Brown, Dick Powell, Ross Alexander Anita Louise, Victor Jory and Ian Hunter.  Produced by Henry Blanke and Hal Wallis for Warner Brothers, and adapted by Charles Kenyon and Mary C. McCall Jr. from Reinhardt's Hollywood Bowl production of the previous year, the film is about the events surrounding the marriage of the Duke of Athens, Theseus, and the Queen of the Amazons, Hippolyta.  These include the adventures of four young Athenian lovers and a group of six amateur actors, who are controlled and manipulated by the fairies who inhabit the forest in which most of the story is set.  The play, which is categorized as a comedy, is one of Shakespeare's most popular works for the stage and is widely performed across the world.  Felix Mendelssohn's music was extensively used, as re-orchestrated by Erich Wolfgang Korngold.  The ballet sequences featuring the fairies were choreographed by Bronislava Nijinska.
