Horologium (constellation)
Horologium (Latin , the pendulum clock, from Ancient Greek, Greek , ) is a constellation of six stars faintly visible in the southern celestial hemisphere. It was first described by the French astronomer Nicolas-Louis de Lacaille in 1756 and visualized by him as a clock with a pendulum and a second hand. In 1922 the constellation was redefined by the International Astronomical Union (IAU) as a region of the celestial sphere containing Lacaille's stars, and has since been an IAU designated constellations, IAU designated constellation. Horologium's associated region is wholly visible to observers south of 23rd parallel north, 23°N. The constellation's brightest star—and the only one brighter than an apparent magnitude of 4—is Alpha Horologii (at 3.85), an aging orange giant star that has swollen to around 11 times the diameter of the Sun. The Mira variable, long-period variable-brightness star, R Horologii (4.7 to 14.3), has one of the largest variations in brightness among al ...

Astronomical Clock
An astronomical clock, horologium, or orloj is a clock with special mechanisms and dials to display astronomical information, such as the relative positions of the Sun, Moon, zodiacal constellations, and sometimes major planets. Definition The term is loosely used to refer to any clock that shows, in addition to the time of day, astronomical information. This could include the location of the Sun and Moon in the sky, the age and Lunar phases, the position of the Sun on the ecliptic and the current zodiac sign, the sidereal time, and other astronomical data such as the Moon's nodes (for indicating eclipses) or a rotating star map. The term should not be confused with ''astronomical regulator'', a high precision but otherwise ordinary pendulum clock used in observatories. Astronomical clocks usually represent the Solar System using the geocentric model. The center of the dial is often marked with a disc or sphere representing the Earth, located at the center of the Solar Sy ...

Horologium Augusti
The Solarium Augusti (also called Horologium Augusti) was an ancient Roman monument in the Campus Martius constructed during the reign of Augustus. It functioned as a giant solar marker, according to various interpretations serving either as a simple meridian line or as a sundial. The obelisk belonged to Egyptian Pharaoh Psamtik II. History It was erected by the emperor Augustus, with the 30-meter Egyptian red granite Obelisk of Montecitorio, that he had brought from Heliopolis in ancient Egypt. The obelisk was employed as a gnomon that cast its shadow on a marble pavement inlaid with a gilded bronze network of lines, by which it was possible to read the time of day according to the season of the year. The ''solarium'' was dedicated to the Sun in 10 BCE, 35 years after Julius Caesar's calendar reform. It was the first solar dedication in Rome. Campus Martius The Solarium Augusti was integrated with the Ara Pacis in the Campus Martius, aligning with Via Flaminia, in such a ...

Horologium Oscillatorium
(English: ''The Pendulum Clock: or Geometrical Demonstrations Concerning the Motion of Pendula as Applied to Clocks'') is a book published by Dutch physicist Christiaan Huygens in 1673 and his major work on pendulums and horology. It is regarded as one of the three most important works on mechanics in the 17th century, the other two being Galileo’s '' Discourses and Mathematical Demonstrations Relating to Two New Sciences'' (1638) and Newton’s (1687). Much more than a mere description of clocks, Huygens's is the first modern treatise in which a physical problem (the accelerated motion of a falling body) is idealized by a set of parameters then analyzed mathematically and constitutes one of the seminal works of applied mathematics.Bruce, I. (2007). Christian Huygens: Horologium Oscillatorium'. Translated and annotated by Ian Bruce. The book is also known for its strangely worded dedication to Louis XIV.. The appearance of the book in 1673 was a political issue, since at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horologium Supercluster
The Horologium-Reticulum Supercluster, is a massive supercluster spanning around 550 million light-years. It has a mass of around 1017 solar masses, similar to that of the Laniakea Supercluster The Laniakea Supercluster (; Hawaiian for "open skies" or "immense heaven") is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies. It was defined in September 2014, when a group of astronom ..., which houses the Milky Way. It is centered on coordinates right ascension and declination , and spans an angular area of 12° × 12°. The nearest part of the supercluster is 700 million light-years away from Earth, while the far end of it is 1.2 billion light-years. It is visible in the constellations Horologium (constellation), Horologium and Eridanus (constellation), Eridanus. The Horologium Supercluster has about 5,000 galaxy groups (30,000 giant galaxies and 300,000 dwarf galaxies). It includes the galaxy cluster Abell 3266. Gallery ...

Turret Clock
A turret clock or tower clock is a clock designed to be mounted high in the wall of a building, usually in a clock tower, in public buildings such as churches, university buildings, and town halls. As a public amenity to enable the community to tell the time, it has a large face visible from far away, and often a striking mechanism which rings bells upon the hours. The turret clock is one of the earliest types of clock. Beginning in 12th century Europe, towns and monasteries built clocks in high towers to strike bells to call the community to prayer. Public clocks played an important timekeeping role in daily life until the 20th century, when accurate watches became cheap enough for ordinary people to afford. Today the time-disseminating functions of turret clocks are not much needed, and they are mainly built and preserved for traditional, decorative, and artistic reasons. To turn the large hands and run the striking train, the mechanism of turret clocks must be more powerf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horologium Sapientiae
''Horologium Sapientiae'' was written by the German Dominican Henry Suso between 1328 and 1330. The book belongs to the tradition of Rhineland mystics and German mysticism. It was quickly translated into a range of European languages and (alongside Pseudo Bonaventure's ''Meditations on the Life of Christ'' and Ludolph of Saxony's ''Life of Christ'') it was one of the three most popular European devotional texts of the fourteenth and fifteenth centuries. Editions and Texts The book was translated into Middle English as ''The Seven Points of True Love and Everlasting Wisdom''; a translation into modern English renders the Latin title "Clock of Wisdom" as ''Wisdom's Watch on the Hours.'' It circulated widely in vernacular languages such as English, French, Dutch, and Italian as well as surviving in more than 233 medieval Latin manuscripts. Contents The Horologium is divided into two books. Book 1 contains 16 chapters and focuses on considerations around Christ's passion whilst b ...

Book Of Hours
The book of hours is a Christian devotional book used to pray the canonical hours. The use of a book of hours was especially popular in the Middle Ages and as a result, they are the most common type of surviving medieval illuminated manuscript. Like every manuscript, each manuscript book of hours is unique in one way or another, but most contain a similar collection of texts, prayers and psalms, often with appropriate decorations, for Christian devotion. Illumination or decoration is minimal in many examples, often restricted to decorated capital letters at the start of psalms and other prayers, but books made for wealthy patrons may be extremely lavish, with full-page miniatures. These illustrations would combine picturesque scenes of country life with sacred images. Books of hours were usually written in Latin (the Latin name for them is ''horae''), although there are many entirely or partially written in vernacular European languages, especially Dutch. The closely related p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horologion
The ''Horologion'' ( grc-gre, Ὡρολόγιον; Church Slavonic: Часocлoвъ, ''Chasoslov'', ro, Ceaslov) or ''Book of hours'' provides the fixed portions (Greek: , ''akolouthiai'') of the Divine Service or the daily cycle of services as used by the Eastern Orthodox and Eastern Catholic churches. Into this fixed framework of the services, are inserted numerous parts changing daily. In its original sense, a ''horologion'' (Greek: ὡρολόγιον, "the hour-teller" from ὥρα ''hṓra'' "hour" and - λόγιον''-logion'', "teller") or Latin '' horologium'' was any device or structure for keeping time, such as a sundial or the Tower of the Winds in Athens. Description The Horologion is primarily a book for the use of the Reader and Chanters (as distinguished from the Euchologion, which contains the texts used by the Priest and Deacon). Several varieties of Horologia exist, the most complete of which is the Great Horologion (Greek: Ὡρολόγιον τò μέ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
