Question: The mosque located in Delhi built is 1505 has an architectural element resembling the hollow upper half of a sphere, what is the element called?
Context: Moth Ki Masjid (moʈʰ kiː masdʒɪd ) is a mosque located in Delhi, and was built in 1505 by Wazir Miya Bhoiya, Prime Minister during the reign of Sikander Lodi (1517–26) of the Lodi dynasty.  It was a new type of mosque developed by the Lodis in the fourth city of the medieval Delhi of the Delhi Sultanate.  The name of the mosque literally translated into English language means ‘Lentil Mosque’ and this name tag ‘Lentil’ has an interesting legend.  This mosque was considered a beautiful Dome (Gumbad) structure of the period. In mathematics, the Schwarz triangle function was introduced by H. A. Schwarz as the inverse function of the conformal mapping uniformizing a Schwarz triangle, i.e. a geodesic triangle in the upper half plane with angles which are either 0 or of the form π over a positive integer greater than one.  Applying successive hyperbolic reflections in its sides, such a triangle generates a tessellation of the upper half plane (or the unit disk after composition with the Cayley transform).  The conformal mapping of the upper half plane onto the interior of the geodesic triangle generalizes the Schwarz–Christoffel transformation.  Through the theory of the Schwarzian derivative, it can be expressed as the quotient of two solutions of a hypergeometric differential equation with real coefficients and singular points at 0, 1 and ∞.  By the Schwarz reflection principle, the discrete group generated by hyperbolic reflections in the sides of the triangle induces an action on the two dimensional space of solutions.  On the orientation-preserving normal subgroup, this two dimensional representation corresponds to the monodromy of the ordinary differential equation and induces a group of Möbius transformations on quotients of solutions.  Since the triangle function is the inverse function of such a quotient, it is therefore an automorphic function for this discrete group of Möbius transformations.  This is a special case of a general method of Henri Poincaré that associates automorphic forms with ordinary differential equations with regular singular points.  In the special case of ideal triangles, where all the angles are zero, the tessellation corresponds to the Farey tessellation and the triangle function yields the modular lambda function. The Great Mosque of Testour (Arabic: الجامع الكبير بتستور‎ ‎ ) is a historical Tunisian mosque located in the city of Testour in Beja Governorate, 76 km from the capital city of Tunis.  The great mosque is located in the center of the old city.  It embodies the Andalusian architecture, especially its minaret, which features Andalusian style inscriptions and architectural elements.  The height of the minaret is 23 meters and it is an octagonal shape.  The facade of the minaret are opened with small double windows decorated with glazed inscriptions and a mechanical clock at the top.  Its appearance is resembling the Aragonese bell towers in southern Spain.  The prayer hall, in addition to the sahn located in the center of the mosque, can accommodate up to 1000 worshipers.  The construction of the mosque used limestone, Spanish sand and marble in addition to colored porcelain and tiles used in the construction of the mihrab.  The mosque dates back to 1631, and its patron is Muhammad Tigharinu. The Lincoln Tree is the name of a huge giant sequoia located in Giant Forest in Sequoia National Park.  It is currently considered by many to be the fourth largest tree in the world.  Wendell Flint, in his book "To Find The Biggest Tree", Sequoia Natural History Association (2002) stated that the Lincoln Tree has a volume of 44471 cuft .  However, White and Pusateri, in "Sequoia and Kings Canyon National Parks", Stanford University Press (1949) indicated that the volume of the Lincoln Tree based on measurements made in the 1930s is 51000 cuft , which would make the Lincoln Tree the second largest tree in the world, after the General Sherman Tree.  Wendell Flint was somewhat critical of the earlier measurements and he stated that he thought that it was appropriate to exclude a portion of the irregular base of the tree from his volume calculations, which in addition to some extrapolation differences from the earlier measurements, explains the smaller volume of 44471 cuft that he obtained compared to the earlier figure.  Although he chose to exclude it, Flint stated that the excluded portion of the base could just as easily be included in the calculations, presumably leading to the alternative volume of 51000 cuft The Lincoln Tree has a maximum base diameter of 36.4 feet.  Nearby trees include the President Tree, the Washington Tree, the Adams Tree, and the Franklin Tree.  All of these trees are of great size, although the Washington Tree lost the hollow upper half of its trunk in 2005 after a fire. Agung Manunggal Bantul Mosque is a mosque located in Jenderal Sudirman st. no.1, Bantul, Yogyakarta, Indonesia.  The mosque contains unique Javanese architectural style resembling Agung Demak Mosque, with characteristics such as mustaka (roof) which resembles Joglo, four saka (pillars) which are carved teak woods, and the entrance in the shape of Gunungan (Javanese iconic Wayang shape).  The mosque can be reached by using private vehicles or public transportation, namely the bus which connects Yogyakarta and Bantul.  From Giwangan terminal, visitors take the bus which bounds to Bantul street then get off at the Klodran intersection.  The mosque is located right in the western part of the Klodran intersection adjacent to Bantul Regency Red Cross as well as a field where functions as parking spaces during large ceremonies. Iveagh Upper, Upper Half is the name of a barony in County Down, Northern Ireland.  It was created by 1851 with the division of the barony of Iveagh Upper into two.  It lies to the west and south of the county, split in half by the Lordship of Newry.  It is bordered by six other baronies: Mourne to the south; Iveagh Upper, Lower Half to the east; Iveagh Lower, Lower Half and Iveagh Lower, Upper Half to the north; and Orior Lower and Orior Upper to the west. A dome (from Latin: "domus") is an architectural element that resembles the hollow upper half of a sphere.  The precise definition has been a matter of controversy.  There are also a wide variety of forms and specialized terms to describe them.  A dome can rest upon a rotunda or drum, and can be supported by columns or piers that transition to the dome through squinches or pendentives.  A lantern may cover an oculus and may itself have another dome. A dome is a self-supporting structural element of architecture that resembles the hollow upper half of a sphere.  This list excludes dome-shaped structures that are not self-supporting such as The O (formerly the Millennium Dome) in London which is 365 m in diameter and supported by masts. Purism is an initial phase of Renaissance architecture in Spain, which took place between 1530 and 1560, after to Isabelline Gothic and prior to the Herrerian architecture in the last third of the 16th century.  The name "Prince Philip" refers to the period in which Philip II of Spain (born in 1527) had not yet received the inheritance of the Spanish Monarchy by abdication of his father the Emperor Charles V (1556).  The name "Serlian" is due to the influential architect and treatise Sebastiano Serlio (in addition to the architectural element called "Serlian" in his honor).  The Greco-Roman, the purist and the casticist are relate to the interpretation given to different elements of style, whether intellectual, formal, structural or decorative.  Until then, writers of the period termed the classicist forms of the Italian Renaissance as the "roman" (Diego de Sagredo "Las Medidas del Romano", 1526), while the late-Gothic forms were called "the modern".  For a more stylistic periodization more common in the art history, at that point of the 16th century the "Cinquecento" had entered in its Mannerist phase, while for the Spanish art is commonly used the expression High Renaissance (reserving the term Low Renaissance for the last third of the century). A dome is a structural element of architecture that resembles the hollow upper half of a sphere.
Answer: A dome
