Organum Mathematicum
The Organum Mathematicum was an information device or the teaching machine that was invented by the Jesuit polymath and scholar Athanasius Kircher in the middle of the 17th century. With proper instruction and use, the device could assist in a wide assortment of calculations, including arithmetic, cryptography, and music. Kircher adopted some of the ideas in the Organum from preexisting inventions like Napier's bones, almanacs, and his own Arca Musarithmica. Like other calculating devices of the period, the Organum prefigures modern computing technology. Yet, due to its general lack of adoption, it remains an interesting but obscure footnote in the history of information technology. Description and layout The Organum Mathematicum was a box or chest divided into nine or more compartments. Each compartment was filled with wooden rods or slats (called "tariffa" by Kircher). The compartments were organized according to the nine functions they performed (see #Topics). To use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arca Musarithmica
The Arca Musarithmica (also Arca Musurgia or Musical Ark) is an information device that was invented by Jesuit scholar Athanasius Kircher in the mid 17th century. Its purpose was to enable non musicians to compose church music. Through simple combinatoric techniques it is capable of producing millions of pieces of 4-part polyphonic music. Like other calculating aids of the period, the Arca prefigures modern computing technology. It is among the earliest examples of "Artificial Creativity". The device anticipates Aleatoric music, aleatoric and computer compositional techniques of the 20th century (such as the "chance music" of John Cage), and can be thought of as a kind of Algorithmic music, music composition algorithm in physical form. Description and mechanism The arca is a box containing a set of wooden rods or slats (or "tariffa" as Kircher called them). Each slat contains a set of numbers, which correspond to notes in a scale or mode, as well as an assortment o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archduke Charles Joseph Of Austria
Charles Joseph (german: Karl Joseph) (7 August 1649 – 27 January 1664) was an Archduke of Austria and Grand Master of the Teutonic Knights (1662–64). He was also the bishop of Olmütz, and Breslau, Passau. Charles Joseph was born in Vienna as the son of Ferdinand III, Holy Roman Emperor and his first cousin, Maria Leopoldine of Austria. His mother died shortly after giving birth to him. Charles Joseph, himself, died in his early teens in Linz Linz ( , ; cs, Linec) is the capital of Upper Austria and third-largest city in Austria. In the north of the country, it is on the Danube south of the Czech border. In 2018, the population was 204,846. In 2009, it was a European Capital ....

Obelisk
An obelisk (; from grc, ὀβελίσκος ; diminutive of ''obelos'', " spit, nail, pointed pillar") is a tall, four-sided, narrow tapering monument which ends in a pyramid-like shape or pyramidion at the top. Originally constructed by Ancient Egyptians and called ''tekhenu'', the Greeks used the Greek term to describe them, and this word passed into Latin and ultimately English. Ancient obelisks are monolithic; they consist of a single stone. Most modern obelisks are made of several stones. Ancient obelisks Egyptian Obelisks were prominent in the architecture of the ancient Egyptians, and played a vital role in their religion placing them in pairs at the entrance of the temples. The word "obelisk" as used in English today is of Greek rather than Egyptian origin because Herodotus, the Greek traveler, was one of the first classical writers to describe the objects. A number of ancient Egyptian obelisks are known to have survived, plus the " Unfinished Obelisk" found part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organum MuseoGalileo Josh Foer
''Organum'' () is, in general, a plainchant melody with at least one added voice to enhance the harmony, developed in the Middle Ages. Depending on the mode and form of the chant, a supporting bass line (or '' bourdon'') may be sung on the same text, the melody may be followed in parallel motion (parallel organum), or a combination of both of these techniques may be employed. As no real independent second voice exists, this is a form of heterophony. In its earliest stages, organum involved two musical voices: a Gregorian chant melody, and the same melody transposed by a consonant interval, usually a perfect fifth or fourth. In these cases the composition often began and ended on a unison, the added voice keeping to the initial tone until the first part has reached a fifth or fourth, from where both voices proceeded in parallel harmony, with the reverse process at the end. Organum was originally improvised; while one singer performed a notated melody (the ''vox principalis'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napier's Bones
Napier's bones is a manually-operated calculating device created by John Napier of Merchiston, Scotland for the calculation of products and quotients of numbers. The method was based on lattice multiplication, and also called ''rabdology'', a word invented by Napier. Napier published his version in 1617. It was printed in Edinburgh and dedicated to his patron Alexander Seton. Using the multiplication tables embedded in the rods, multiplication can be reduced to addition operations and division to subtractions. Advanced use of the rods can extract square roots. Napier's bones are not the same as logarithms, with which Napier's name is also associated, but are based on dissected multiplication tables. The complete device usually includes a base board with a rim; the user places Napier's rods inside the rim to conduct multiplication or division. The board's left edge is divided into nine squares, holding the numbers 1 to 9. In Napier's original design, the rods are made of metal, w ...

Gaspar Schott
Gaspar Schott (German: ''Kaspar'' (or ''Caspar'') ''Schott''; Latin: ''Gaspar Schottus''; 5 February 1608 – 22 May 1666) was a German Jesuit and scientist, specializing in the fields of physics, mathematics and natural philosophy, and known for his industry. Biography He was born at Bad Königshofen im Grabfeld. It is probable, but not certain, that his early education was at the Jesuit College at Würzburg. In any case, at the age of 19 he joined the Society of Jesus, entering the novitiate at Trier on 30 October 1627. After two years of novitiate training, he matriculated at the University of Würzburg on 6 November 1629 to begin a three-year study of Philosophy, following the normal academic path prescribed for Jesuit seminarians. Owing to the Swedish invasion of Würzburg in October 1631, the Jesuit community fled the city. Schott went, first to the Jesuit seminary of Tournai in Belgium, and subsequently, in 1633, to Caltagirone in Sicily, where he continued his study of T ...

Musurgia Universalis
''Musurgia Universalis, sive Ars Magna Consoni et Dissoni'' ("The Universal Musical Art, of the Great Art of Consonance and Dissonance") is a 1650 work by the Jesuit scholar Athanasius Kircher. It was printed in Rome by Ludovico Grignani and dedicated to Archduke Leopold Wilhelm of Austria. It was a compendium of ancient and contemporary thinking about music, its production and its effects. It explored, in particular, the relationship between the mathematical properties of music (e.g. harmony and dissonance) with health and rhetoric. The work complements two of Kircher's other books: '' Magnes sive de Arte Magnetica'' had set out the secret underlying coherence of the universe and ''Ars Magna Lucis et Umbrae'' had explored the ways of knowledge and enlightenment. What ''Musurgia Universalis'' contained, through its exploration of dissonance within harmony, was an explanation of the presence of evil in the world. Composition and publication Kircher compiled all the musical knowle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

He taught for more than 40 years at the Roman College, where he set up a wunderkammer. A resurgence of interest in Kircher has occurred within the scholarly community in recent decades. Kircher claimed to have deciphered the Egyptian hieroglyphs, hieroglyphic writing of the ancient Egyptian language, but most of ...
