Exeter Cathedral Astronomical Clock
The Exeter Cathedral Astronomical Clock is a fifteenth-century astronomical clock in Exeter Cathedral, England. It displays the hour of the day, the day of the lunar month and the phase of the moon. The modern clock mechanism was installed in 1885 by Gillett & Bland of Croydon, and restored in 1910. History and description The clock is thought to date from around 1484. The outermost numbered circle of the main dial is decorated with a fleur-de-lis which represents the Sun, and which orbits the dial once every 24 hours. This indicates the hour of the day, counted from I to XII in Roman numerals in first the right and then the left hemispheres of the clockface. This is an example of a 24-hour analog dial. The tail of the Sun's fleur-de-lis points to the day in the lunar month on the inner numbered ring. The half-black, half-silver Moon inside the lunar month ring rotates on its axis to show the correct phase of the moon. The Earth is represented as a fixed golden ball in the ce ...

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 ...

Exeter Cathedral
Exeter Cathedral, properly known as the Cathedral Church of Saint Peter in Exeter, is an Anglican cathedral, and the seat of the Bishop of Exeter, in the city of Exeter, Devon, in South West England. The present building was complete by about 1400, and has several notable features, including an early set of misericords, an astronomical clock and the longest uninterrupted medieval stone vaulted ceiling in the world. History The founding of the cathedral at Exeter, dedicated to Saint Peter, dates from 1050, when the seat of the bishop of Devon and Cornwall was transferred from Crediton because of a fear of sea-raids. A Saxon minster already existing within the town (and dedicated to Saint Mary and Saint Peter) was used by Leofric as his seat, but services were often held out of doors, close to the site of the present cathedral building. In 1107 William Warelwast was appointed to the see, and this was the catalyst for the building of a new cathedral in the Norman style. Its ...

Lunar Month
In lunar calendars, a lunar month is the time between two successive syzygies of the same type: new moons or full moons. The precise definition varies, especially for the beginning of the month. Variations In Shona, Middle Eastern, and European traditions, the month starts when the young crescent moon first becomes visible, at evening, after conjunction with the Sun one or two days before that evening (e.g., in the Islamic calendar). In ancient Egypt, the lunar month began on the day when the waning moon could no longer be seen just before sunrise. Others run from full moon to full moon. Yet others use calculation, of varying degrees of sophistication, for example, the Hebrew calendar or the ecclesiastical lunar calendar. Calendars count integer days, so months may be 29 or 30 days in length, in some regular or irregular sequence. Lunar cycles are prominent, and calculated with great precision, in the ancient Hindu Panchangam calendar, widely used in the Indian subcontin ...

Phase Of The Moon
Concerning the lunar month of ~29.53 days as viewed from Earth, the lunar phase or Moon phase is the shape of the Moon's directly sunlit portion, which can be expressed quantitatively using areas or angles, or described qualitatively using the terminology of the 4 major phases: new moon, first quarter, full moon, last quarter and 4 minor phases: waxing crescent, waxing gibbous, waning gibbous, and waning crescent. The lunar phases gradually change over a synodic month (~29.53 days) as the Moon's orbital positions around Earth and Earth around the Sun shift. The visible side of the Moon is variously sunlit, depending on the position of the Moon in its orbit. Thus, this face's sunlit portion can vary from 0% (at new moon) to 100% (at full moon). Each of the 4 major lunar phases (see below) is ~7.4 days, with +/− 19 hours in variation (6.58–8.24 days) due to the elliptical shape of the Moon's orbit. Phases of the Moon There are four ''principal'' (primary/major) lunar phase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gillett & Bland
Gillett & Johnston was a clockmaker and bell foundry based in Croydon, England from 1844 until 1957. Between 1844 and 1950, over 14,000 tower clocks were made at the works. The company's most successful and prominent period of activity as a bellfounder was in the 1920s and 1930s, when it was responsible for supplying many important bells and carillons for sites across Britain and around the world. A successor company continues operation in Bletchingley, Surrey, under the Gillett & Johnston name, engaged in clock-making and clock and carillon repair. History The company traced its roots to a clockmaking business established by William Gillett in Hadlow, Kent, in the early 19th century. In 1837, Gillett moved his business to Clerkenwell, London; and in 1844 to the site in what later became known as Union Road, Thornton Heath, Croydon, which would remain its home for the next 113 years. Charles Bland became a partner in 1854, and the company subsequently traded as Gillett & Blan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fleur-de-lis
The fleur-de-lis, also spelled fleur-de-lys (plural ''fleurs-de-lis'' or ''fleurs-de-lys''), is a lily (in French, and mean 'flower' and 'lily' respectively) that is used as a decorative design or symbol. The fleur-de-lis has been used in the heraldry of numerous European nations, but is particularly associated with France, notably during its monarchical period. The fleur-de-lis became "at one and the same time, religious, political, dynastic, artistic, emblematic, and symbolic," especially in French heraldry. The fleur-de-lis has been used by French royalty and throughout history to represent saints of France. In particular, the Virgin Mary and Saint Joseph are often depicted with a lily. The fleur-de-lis is represented in Unicode at in the Miscellaneous Symbols block. Origin The ''fleur de lis'' is widely thought to be a stylized version of the species ''Iris pseudacorus'', or ''Iris florentina''.Stefan Buczacki However, the lily (genus lilium, family Liliaceae) and the ...

Roman Numerals
Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers are written with combinations of letters from the Latin alphabet, each letter with a fixed integer value, modern style uses only these seven: The use of Roman numerals continued long after the decline of the Roman Empire. From the 14th century on, Roman numerals began to be replaced by Arabic numerals; however, this process was gradual, and the use of Roman numerals persists in some applications to this day. One place they are often seen is on clock faces. For instance, on the clock of Big Ben (designed in 1852), the hours from 1 to 12 are written as: The notations and can be read as "one less than five" (4) and "one less than ten" (9), although there is a tradition favouring representation of "4" as "" on Roman numeral clocks. Other common uses include year numbers on monuments and buildings and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
24-hour Analog Dial
Clocks and watches with a 24-hour analog dial have an hour hand that makes one complete revolution, 360°, in a day (24 hours per revolution). The more familiar 12-hour analog dial has an hour hand that makes two complete revolutions in a day (12 hours per revolution). Twenty-four-hour analog clocks and watches are used today by logistics workers, fire fighters, police officers, paramedics, nurses, pilots, scientists, and the military, and are sometimes preferred because of the unambiguous representation of a whole day at a time. Note that this definition refers to the use of a complete circular dial to represent a 24-hour day. Using the numbers from 0 to 23 (or 1 to 24) to mark the day is the '' 24-hour clock system''. Sundials use 24-hour analog dials—the shadow traces a path that repeats approximately once per day. Many sundials are marked with the double-XII or double-12 system, in which the numbers I to XII (or 1 to 12) are used twice, once for the morning hours, ...

John James Hall
John James Hall FRAS (11 December 1845 – 15 January 1941) was an eminent horologist and author who restored many early clocks. Life John James Hall spent his working life as an employee of the London and South Western Railway from 1865, but on retirement devoted his time to horology. He made over 200 contributions to ''The Horological Journal'', ''The English Mechanic and World of Science'', ''Watch and Clockmaker'' and other journals. His best known accomplishments were the restoration of the fourteenth-century astronomical clocks in St Mary's Church, Ottery St Mary in 1907 and Exeter Cathedral in 1910. He designed a new clock for Exeter Public Library which was set going in 1931. One of his major areas of study was the life and work of Jacob Lovelace of Exeter. He also published his complete articles in ''Fasces Exonienses''. He was elected a Fellow of the Royal Astronomical Society on 10 February 1899. He was also a Fellow of the British Horological Institute, the Met ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
