History Of Early Modern Period Domes
Domes built in the 16th, 17th, and 18th centuries relied primarily on empirical techniques and oral traditions rather than the architectural treatises of the time, but the study of dome structures changed radically due to developments in mathematics and the study of statics. Analytical approaches were developed and the ideal shape for a dome was debated, but these approaches were often considered too theoretical to be used in construction. The Gothic ribbed vault was displaced with a combination of dome and barrel vaults in the Renaissance style throughout the sixteenth century. The use of lantern towers, or timburios, which hid dome profiles on the exterior declined in Italy as the use of windowed drums beneath domes increased, which introduced new structural difficulties. The spread of domes in this style outside of Italy began with central Europe, although there was often a stylistic delay of a century or two. Use of the oval dome spread quickly through Italy, Spain, France, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Statics
Statics is the branch of classical mechanics that is concerned with the analysis of force and torque (also called moment) acting on physical systems that do not experience an acceleration (''a''=0), but rather, are in static equilibrium with their environment. The application of Newton's second law to a system gives: : \textbf F = m \textbf a \, . Where bold font indicates a vector that has magnitude and direction. \textbf F is the total of the forces acting on the system, m is the mass of the system and \textbf a is the acceleration of the system. The summation of forces will give the direction and the magnitude of the acceleration and will be inversely proportional to the mass. The assumption of static equilibrium of \textbf a = 0 leads to: : \textbf F = 0 \, . The summation of forces, one of which might be unknown, allows that unknown to be found. So when in static equilibrium, the acceleration of the system is zero and the system is either at rest, or its center of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prague Castle
Prague Castle ( cs, Pražský hrad; ) is a castle complex in Prague 1 Municipality within Prague, Czech Republic, built in the 9th century. It is the official office of the President of the Czech Republic. The castle was a seat of power for kings of Bohemia, Holy Roman emperors, and presidents of Czechoslovakia.

Paul Guldin
Paul Guldin (born Habakkuk Guldin; 12 June 1577 ( Mels) – 3 November 1643 (Graz)) was a Swiss Jesuit mathematician and astronomer. He discovered the Guldinus theorem to determine the surface and the volume of a solid of revolution. (This theorem is also known as the Pappus–Guldinus theorem and Pappus's centroid theorem, attributed to Pappus of Alexandria.) Guldin was noted for his association with the German mathematician and astronomer Johannes Kepler. Guldin composed a critique of Cavalieri's method of Indivisibles. Although of Jewish descent, his parents were Protestants and they brought Guldin up in that faith. He was a professor of mathematics in Graz and Vienna. In Paolo Casati's astronomical work ''Terra machinis mota'' (1658), Casati imagines a dialogue among Guldin, Galileo, and Marin Mersenne on various intellectual problems of cosmology, geography, astronomy and geodesy.

Philibert De L'Orme
Philibert de l'Orme () (3-9 June 1514 – 8 January 1570) was a French architect and writer, and one of the great masters of French Renaissance architecture. His surname is also written De l'Orme, de L'Orme, or Delorme. Biography Early career Philbert de l'Orme was born between 3 and 9 June 1514 in Lyon. His father was Jehan de L'Orme, a master mason and entrepreneur, who, in the 1530s, employed three hundred workers and built prestigious buildings for the elite of the city.Boudon 1999, p. 204. When Philibert was nineteen he departed Lyon for Italy, where he remained for three years, working on building projects for Pope Paul III. In Rome he was introduced to Cardinal Jean du Bellay, the Ambassador of King François I to the Vatican, who became his protector and client. Du Bellay was also the patron of his friend Francois Rabelais. In about 1540 de l'Orme moved to Paris, and was soon occupied with royal projects. Royal architect of Henry II (1548-1559) On April 3, 1548 h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albrecht Dürer
Albrecht Dürer (; ; hu, Ajtósi Adalbert; 21 May 1471 – 6 April 1528),Müller, Peter O. (1993) ''Substantiv-Derivation in Den Schriften Albrecht Dürers'', Walter de Gruyter. . sometimes spelled in English as Durer (without an umlaut) or Duerer, was a German painter, printmaker, and theorist of the German Renaissance. Born in Nuremberg, Dürer established his reputation and influence across Europe in his twenties due to his high-quality woodcut prints. He was in contact with the major Italian artists of his time, including Raphael, Giovanni Bellini, and Leonardo da Vinci, and from 1512 was patronized by Emperor Maximilian I. Dürer's vast body of work includes engravings, his preferred technique in his later prints, altarpieces, portraits and self-portraits, watercolours and books. The woodcuts series are more Gothic than the rest of his work. His well-known engravings include the three '' Meisterstiche'' (master prints) '' Knight, Death and the Devil'' (1513), '' Saint ...

Elliptical Dome
An elliptical dome, or an ''oval dome'', is a dome whose bottom cross-section takes the form of an ellipse. Technically, an ''ellipsoidal dome'' has a circular cross-section, so is not quite the same. While the cupola can take different geometries, when the ceiling's cross-section takes the form of an ellipse, and due to the reflecting properties of an ellipse, any two persons standing at a focus of the floor's ellipse can have one whisper, and the other hears; this is a whispering gallery. The largest elliptical dome in the world is at the Sanctuary of Vicoforte in Vicoforte, Italy. In architecture Elliptical domes have many applications in architecture; and are useful in covering rectangular spaces. The oblate, or horizontal elliptical dome is useful when there is a need to limit height of the space that would result from a spherical dome. As the mathematical description of an elliptical dome is more complex than that of spherical dome, design care is needed. In a geode ...

Basilica Of Saint Anthony Of Padua
The Pontifical Basilica of Saint Anthony of Padua ( it, Basilica Pontificia di Sant'Antonio di Padova) is a Catholic church and minor basilica in Padua, Veneto, Northern Italy, dedicated to St. Anthony of Padua. Although the basilica is visited as a place of pilgrimage by people from all over the world, it is not the cathedral of the city, a title belonging to the Cathedral-Basilica of St. Mary of Padua. The basilica is known locally as "il Santo". It is one of the national shrines recognized by the Holy See. History Construction of the Basilica probably began around 1232, just one year after the death of St. Anthony. It was completed in 1310 although several structural modifications (including the falling of the ambulatory and the construction of a new choir screen) took place between the end of the 14th and the mid-15th century. The Saint, according to his will, had been buried in the small church of ''Santa Maria Mater Domini'', probably dating from the late 12th centur ...

San Giorgio Maggiore (church), Venice
San Giorgio Maggiore (San Zorzi Mazor in Venetian) is a 16th-century Benedictine church on the island of the same name in Venice, northern Italy, designed by Andrea Palladio, and built between 1566 and 1610. The church is a basilica in the classical Renaissance style and its brilliant white marble gleams above the blue water of the lagoon opposite the Piazzetta di San Marco and forms the focal point of the view from every part of the Riva degli Schiavoni. History The first church on the island was built about 790, and in 982 the island was given to the Benedictine order by the Doge Tribuno Memmo. The Benedictines founded a monastery there, but in 1223 all the buildings on the island were destroyed by an earthquake. The church and monastery were rebuilt after the earthquake. The church, which had a nave with side chapels, was not in the same position as the present church, but farther back at the side of a small campo or square. There were cloisters in front of it, which were de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mantua Cathedral
Mantua Cathedral ( it, Cattedrale di San Pietro apostolo; Duomo di Mantova) in Mantua, Lombardy, northern Italy, is a Roman Catholic cathedral dedicated to Saint Peter. It is the seat of the Bishop of Mantua. History An initial structure probably existed on the site in the Early Christian era, which was followed by a building destroyed by a fire in 894. The current church was rebuilt in 1395–1401 with the addition of side chapels and a Gothic west front, which can still be seen in a sketch by Domenico Morone (preserved in the Palazzo Ducale of Mantua). The bell tower has seven bells tuned in the scale of Bb. The organ of the cathedral was built by Hans Tugi in c. 1503. After another fire in the 16th century, Giulio Romano rebuilt the interior but saved the frontage, which was replaced however in 1756–61 by the current Baroque one in Carrara marble. Notable characteristics of the Renaissance structure are the cusps, decorated with rose windows on the south side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Padua
Padua ( ; it, Padova ; vec, Pàdova) is a city and ''comune'' in Veneto, northern Italy. Padua is on the river Bacchiglione, west of Venice. It is the capital of the province of Padua. It is also the economic and communications hub of the area. Padua's population is 214,000 (). The city is sometimes included, with Venice (Italian ''Venezia'') and Treviso, in the Padua-Treviso-Venice Metropolitan Area (PATREVE) which has a population of around 2,600,000.

Abbey Of Santa Giustina
The Abbey of Santa Giustina is a 10th-century Benedictine abbey complex located in front of the Prato della Valle in central Padua, region of Veneto, Italy. Adjacent to the former monastery is the basilica church of Santa Giustina, initially built in the 6th century, but whose present form derives from a 17th-century reconstruction. History A church dedicated to the St Justina of Padua and of other 4th century Christian martyrs of Padua, was present at the site by the 520s, erected under the patronage of the Prefect Opilius and housing the relics of the saint. The church was already described as lavish in decoration in the 565 biography of ''Life of St Martin'', written by Venantius Fortunatus. By the 10th century, pilgrims who came to the basilica to venerate the saints' relics, were ministered by monks. In 971, Bishop of Padua placed the community under the Rule of St. Benedict. Renovations were soon begun on the basilica. On 2 August 1052, workers putatively exhumed remains of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
