Lala Balhumal Lahori
Lāla Bulhomal (also Balhumal) Lāhorī was an Indian metallurgist and instrument maker from the city of Lahore in modern Pakistan. He was famous for crafting ornate astrolabes and celestial globes made in the tradition of Indo-Persian instruments. The toponymic surname Lāhorī indicates that he came from Lahore, while the prefix Lāla is an honorific indicating social status. His instruments, likely made between 1839 and 1851, were constructed mainly of brass, with inscriptions in Sanskrit, Devanagari, Arabic, and Persian. He is known to have produced at least twenty-eight such instruments. Forty-five instruments produced by Bulhomal and his associates are known to exist in museums and collections around the world; an 1849 astrolabe crafted for Sir Henry Miers Elliot, an officer of the East India Company, is now in the Science Museum, London. Bulhomal's patron was Nihal Singh Ahluwalia, the Raja of Kapurthala (1837–1852), and his apprentices included Ghulām Qādir Kapūrthalī an ...

Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals; that is, the way in which science is applied to the production of metals, and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mi ...

Astrolabe
An astrolabe ( grc, ἀστρολάβος ; ar, ٱلأَسْطُرلاب ; persian, ستارهیاب ) is an ancient astronomical instrument that was a handheld model of the universe. Its various functions also make it an elaborate inclinometer and an analog calculation device capable of working out several kinds of problems in astronomy. In its simplest form it is a metal disc with a pattern of wires, cutouts, and perforations that allows a user to calculate astronomical positions precisely. Historically used by astronomers, it is able to measure the altitude above the horizon of a celestial body, day or night; it can be used to identify stars or planets, to determine local latitude given local time (and vice versa), to survey, or to triangulate. It was used in classical antiquity, the Islamic Golden Age, the European Middle Ages and the Age of Discovery for all these purposes. The astrolabe's importance comes not only from the early developments into the study of astron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armillary Sphere
An armillary sphere (variations are known as spherical astrolabe, armilla, or armil) is a model of objects in the sky (on the celestial sphere), consisting of a spherical framework of rings, centered on Earth or the Sun, that represent lines of celestial longitude and latitude and other astronomically important features, such as the ecliptic. As such, it differs from a celestial globe, which is a smooth sphere whose principal purpose is to map the constellations. It was invented separately first in ancient China during the 4th century BC and ancient Greece during the 3rd century BC, with later uses in the Islamic world and Medieval Europe. With the Earth as center, an armillary sphere is known as ''Ptolemaic''. With the Sun as center, it is known as '' Copernican''. The flag of Portugal features an armillary sphere. The armillary sphere is also featured in Portuguese heraldry, associated with the Portuguese discoveries during the Age of Exploration. Manuel I of Portugal, for ...

Henry Miers Elliot
Sir Henry Miers Elliot (1 March 1808 – 20 December 1853) was an English civil servant and historian who worked with the East India Company in India for 26 years. He is most known for ''The History of India, as Told by Its Own Historians'' based on his works, published posthumously in eight volumes, between 1867–1877 in London. Early life and background Elliot was born on 1 March 1808. He was the third son, one of fifteen children, of John Elliot, of Pimlico Lodge, Westminster, colonel commandant of the Westminster volunteers, and a daughter of John Coakley Lettsom, M.D. Born in 1808, he was educated from the age of ten at Winchester College, and destined for New College, Oxford; but the demand of the East India Company for civilians beyond the numbers regularly trained at Haileybury tempted him to try for an appointment in their service, and he was the first of the ' competition wallahs' to pass an open examination for an immediate post in India. His oriental languages as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East India Company
The East India Company (EIC) was an English, and later British, joint-stock company founded in 1600 and dissolved in 1874. It was formed to trade in the Indian Ocean region, initially with the East Indies (the Indian subcontinent and Southeast Asia), and later with East Asia. The company seized control of large parts of the Indian subcontinent, colonised parts of Southeast Asia and Hong Kong. At its peak, the company was the largest corporation in the world. The EIC had its own armed forces in the form of the company's three Presidency armies, totalling about 260,000 soldiers, twice the size of the British army at the time. The operations of the company had a profound effect on the global balance of trade, almost single-handedly reversing the trend of eastward drain of Western bullion, seen since Roman times. Originally chartered as the "Governor and Company of Merchants of London Trading into the East-Indies", the company rose to account for half of the world's trade duri ...

Lost-wax Casting
Lost-wax casting (also called "investment casting", "precision casting", or ''cire perdue'' which has been adopted into English from the French, ) is the process by which a duplicate metal sculpture (often silver, gold, brass, or bronze) is cast from an original sculpture. Intricate works can be achieved by this method. The oldest known examples of this technique are approximately 6,500-year-old (4550–4450 BC) and attributed to gold artefacts found at Bulgaria's Varna Necropolis. A copper amulet from Mehrgarh, Indus Valley civilization, in Pakistan, is dated to circa 4,000 BC. Cast copper objects, found in the Nahal Mishmar hoard in southern Israel, which belong to the Chalcolithic period (4500–3500 BC), are estimated, from carbon-14 dating, to date to circa 3500 BC. In Other examples from somewhat later periods are from Mesopotamia in the third millennium BC. Lost-wax casting was widespread in Europe until the 18th century, when a piece-moulding process came to predomi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
