[Q]: Paragraph:   The Gregorian Tower ( Italian : Torre Gregoriana ) or Tower of the Winds ( Italian : Torre dei Venti ) is a round tower located above the Gallery of Maps , which connects the Villa Belvedere with the Apostolic Palace in Vatican City . The tower was built between 1578 and 1580 to a design by the Bolognese architect Ottaviano Mascherino ( who was credited with building the Apostolic Palace ) mainly to promote the study of astronomy for the Gregorian Calendar Reform which was commissioned by Pope Gregory XIII and promulgated in 1582 . It was then also known as the Tower of Winds . The tower is now called the " Specola Astronomica Vaticana " , the Vatican Observatory . Four stages of progressive development have occurred since it was first established . The tower was an edifice of great value for astronomical observations made using a sundial as they provided essential confirmation of the need to reform the Julian calendar .

[Q]: Paragraph:    Fairies became a popular theme in art and literature in the early 20th century following the releases of The Coming of the Fairies by Sir Arthur Conan Doyle , Peter Pan by J.M. Barrie , and the fairy @-@ themed work of Australian Ida Rentoul Outhwaite . Queen Mary made such themes even more popular by sending Outhwaite postcards to friends during the 1920s .

 In 1923 , Barker sent her flower fairy paintings to various publishers . Blackie paid £ 25 for 24 paintings with accompanying verses , but it wasn 't until publication of Flower Fairies of the Summer in 1925 that Barker received royalties for her work . Mary Violet Clayton Calthrop , wife of author Dion Clayton Calthrop , wrote in April 1925 about Barker and Flower Fairies of the Spring : " She has such exquisite taste , besides draughtsmanship . "   Question: what is the suitable title of the passage ?

[Q]: Paragraph:    In 1924 , the family moved into a four @-@ level , semi @-@ detached Victorian house at 23 The Waldrons . Barker had a studio built in the garden and her sister conducted a kindergarten in a room at the back of the house . The family lived frugally and attended both St. Edmund 's and St. Andrew 's in Croydon – " low " churches for the less privileged . Barker sometimes incorporated portraits of her fellow parishioners in her religious works . She was described by Canon Ingram Hill as " one of the pillars " of St. Andrew 's . 
 The children in the kindergarten modelled for the Flower Fairies until the kindergarten closed in 1940 . In an interview in 1958 , Barker said , " My sister ran a kindergarten and I used to borrow her students for models . For many years I had an atmosphere of children about me – I never forgot it . " She also painted the children of relatives as well as Gladys Tidy , the Barkers ' young housekeeper , who posed for the Primrose Fairy in 1923 . The plants were painted from life , and if a specimen was not readily at hand , Kew Gardens staff would provide her the specimens needed . Barker designed and built the Flower Fairy costumes , and based each on the flowers and leaves of the particular plant to be illustrated . The costumes were kept in a trunk in her studio along with wings made of twigs and gauze . Each was broken down after an illustration was completed and the parts recycled for other costumes . She often referred to Dion Clayton Calthrop 's English Costume .   Question: what is the suitable title of the passage ?
