Bookwheel
The bookwheel (also written book wheel and sometimes called a reading wheel) is a type of rotating bookcase that allows one person to read multiple books in one location with ease. The books are rotated vertically similar to the motion of a water wheel, as opposed to rotating on a flat table surface. The design for the bookwheel originally appeared in a 16th-century illustration by Agostino Ramelli at a time when large books posed practical problems for readers. Ramelli's design influenced other engineers and, though now obsolete, inspires modern artists and historians. History and design The bookwheel, in its most commonly seen form, was invented in 1588 by Italian military engineer Agostino Ramelli, presented as one of the 195 designs in ''Le diverse et artificiose machine del Capitano Agostino Ramelli'' (''The various and ingenious machines of Captain Agostino Ramelli'').Brashear, Ronald"Ramelli's Machines: Original drawings of the 16th century machines" Smithsonian Libraries. ...

Nicolas Grollier De Servière
Nicolas Grollier de Servière (1596–1689) was a French inventor and ornamental turner who became well known for creating a series of fantastic machines. Grollier de Servière, a cousin of Jean Grolier de Servières (1489/90–1565), Treasurer of France and famed bibliophile, was born in Lyon, the fourth son of Antoine Grollier de ServièreRoger Le Roux de Lincy, baron Portalis, 1907. ''Researches Concerning Jean Grolier: His Life and His Library'' pp25ff. and in his youth followed a military career that took him to Flanders, Germany, Italy and Constantinople; as an engineer, he specialized in deploying movable bridges in the field. After he retired to his home in Lyon, he worked on ornamental lathe-work and built a series of fantastic models. He displayed his work in a cabinet that he opened to the public once a week and which became famous enough to attract politicians, scholars, artisans and other inventors. It featured model water pumps and Archimedes' screws, siege engin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agostino Ramelli
Agostino Ramelli (1531–ca. 1610) was an Italian engineer best known for writing and illustrating the book of engineering designs ''Le diverse et artificiose machine del Capitano Agostino Ramelli'', which contains, among others, his design for the bookwheel. Ramelli was born in Ponte Tresa or Mesanzena, today in Switzerland. During the Siege of La Rochelle (1572–1573), he successfully engineered a mine under a bastion and breached the fortification,"One Good Turn: A Natural History of the Screwdriver and Screw" Witold Rybczynski p.47 making him popular with his commander, Henri d'Anjou, who later became King Henri III of France. In 1588 Ramelli published ''Le diverse et artificiose machine del Capitano Agostino Ramelli'', or ''The various and ingenious machines of Captain Agostino Ramelli''. The book contains 195 designs, over 100 of which are water-raising machines, such as water pumps or wells.Brashear, RonaldRamelli's Machines Smithsonian Libraries. Other design ...

Bibliotheca Thysiana
The Bibliotheca Thysiana was erected in 1655 to house the book collection of the lawyer Johannes Thysius (1621–1653). Upon his early death, he left a legacy of 20,000 guilders for the building of a public library ("tot publycque dienst der studie") with a custodian's dwelling. Designed by the architect Arent van ‘s-Gravensande, the building follows the Dutch Classical style and is regarded as one of the jewels of Dutch 17th-century architecture. Bibliotheca Thysiana is one of the Top 100 Dutch heritage sites. It is distinguished by its balanced proportions and the purity of its Ionic order on top of a high basement. The ''Bibliotheca Thysiana'' is the only surviving 17th century example in the Netherlands of a building that was designed as a public library. It is quite extraordinary that a complete private 17th century library has been preserved and thus offers a good impression of the book collection of a young, learned bibliophile from the period of late Humanism.

Epicyclic Gearing
An epicyclic gear train (also known as a planetary gearset) consists of two gears mounted so that the center of one gear revolves around the center of the other. A carrier connects the centers of the two gears and rotates the planet and sun gears mesh so that their pitch circles roll without slip. A point on the pitch circle of the planet gear traces an epicycloid curve. In this simplified case, the sun gear is fixed and the planetary gear(s) roll around the sun gear. An epicyclic gear train can be assembled so the planet gear rolls on the inside of the pitch circle of a fixed, outer gear ring, or ring gear, sometimes called an ''annular gear''. In this case, the curve traced by a point on the pitch circle of the planet is a hypocycloid. The combination of epicycle gear trains with a planet engaging both a sun gear and a ring gear is called a ''planetary gear train''.J. J. Uicker, G. R. Pennock and J. E.

Global Spread Of The Printing Press
The global spread of the printing press began with the invention of the printing press with movable type by Johannes Gutenberg in Mainz, Germany . Western printing technology was adopted in all world regions by the end of the 19th century, displacing the manuscript and block printing. In the Western world, the operation of a press became synonymous with the enterprise of publishing and lent its name to a new branch of media, the "press" (see List of the oldest newspapers). Spread of the Gutenberg press Germany Gutenberg's first major print work was the 42-line Bible in Latin, printed probably between 1452 and 1454 in the German city of Mainz. After Gutenberg lost a lawsuit against his investor, Johann Fust, Fust put Gutenberg's employee Peter Schöffer in charge of the print shop. Thereupon Gutenberg established a new one with the financial backing of another money lender. With Gutenberg's monopoly revoked, and the technology no longer secret, printing spread throughout G ...

Bibliothèque De L'Arsenal
The Bibliothèque de l'Arsenal (''Library of the Arsenal'', founded 1757) in Paris has been part of the Bibliothèque nationale de France since 1934. History The collections of the library originated with the private library of Marc-René, 3rd marquis d'Argenson (1722–1787), installed in 1757 in the residence of the Grand Master of the Artillery, at the heart of the ancient Arsenal of Paris. The Arsenal itself was founded by King François I in the 16th century, later rebuilt by Sully, and expanded by the architect Germain Boffrand in the 18th century. Paulmy had assembled a magnificent collection, particularly rich in medieval manuscripts and prints. In 1786 he also acquired the collection of the duc de la Vallière, but then sold the entire library to the comte d'Artois. The library was sequestered by the state during the French Revolution, and was greatly expanded by many valuable items seized from the abbeys of Paris and also by the archives of the Bastille.

Lambach Abbey
Lambach Abbey (german: Stift Lambach) is a Benedictine monastery in Lambach in the Wels-Land district of Upper Austria, Austria. History A monastery was founded in Lambach in about 1040 by Count Arnold II of Lambach-Wels. His son, Bishop Adalbero of Würzburg (later canonised), changed the monastery into a Benedictine abbey in 1056, which it has been since. During the 17th and 18th centuries a great deal of work in the Baroque style was carried out, much of it by the Carlone family. Lambach escaped the dissolution of the monasteries of Emperor Joseph II in the 1780s. In 1897/98, Adolf Hitler lived in the town of Lambach with his parents and attended the monastery school, where he saw the hakenkreuz used in decorative carving on the stone and woodwork of the building. He later used it as a symbol for the Nazi Party, placing it in a white circle with a red background for use as a flag. Cultural features Between Easter Sunday and 31. of October guided tours are offered every day a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Klosterneuburg Monastery
Klosterneuburg Abbey or Monastery (german: Stift Klosterneuburg) is a twelfth-century Augustinian monastery of the Roman Catholic Church located in the town of Klosterneuburg in Lower Austria. Overlooking the Danube, just north of the Vienna city limits at the Leopoldsberg, the monastery was founded in 1114 by Saint Leopold III of Babenberg, the patron saint of Austria, and his second wife Agnes of Germany. The abbey church, dedicated the Nativity of Mary (''Maria Geburt''), was consecrated in 1136 and remodeled in the Baroque style in the seventeenth century.
