Michael Sendivogius
Michael Sendivogius (; pl, Michał Sędziwój; 2 February 1566 – 1636) was a Polish alchemist, philosopher, and medical doctor. A pioneer of chemistry, he developed ways of purification and creation of various acids, metals and other chemical compounds. He discovered that air is not a single substance and contains a life-giving substance—later called oxygen—170 years before Scheele's discovery of the element. He correctly identified this 'food of life' with the gas (also oxygen) given off by heating nitre (saltpetre). This substance, the 'central nitre', had a central position in Sendivogius' schema of the universe. Biography Little is known of his early life: he was born in a noble family that was part of the Clan of Ostoja. His father sent him to study in university of Kraków but Sendivogius visited also most of the European countries and universities; he studied at Vienna, Altdorf, Leipzig and Cambridge. His acquaintances included John Dee and Edward Kelley. It w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Kelley
Sir Edward Kelley or Kelly, also known as Edward Talbot (; 1 August 1555 – 1597/8), was an English Renaissance occultist and scryer. He is best known for working with John Dee in his magical investigations. Besides the professed ability to see spirits or angels in a "shew-stone" or mirror, which John Dee so valued, Kelley also claimed to possess the secret of transmuting base metals into gold, the goal of alchemy, as well as the supposed philosopher's stone itself. Legends began to surround Kelley shortly after his death. His flamboyant biography, his relationships with Queen Elizabeth I's royal magus Sir John Dee and the Emperor Rudolf II, and his claims of great alchemical skill and the ability to communicate with angels have all led to his relative notoriety among historians. Biography Birth and early career Much of Kelley's early life is obscure. He claimed descent from the family of Ui Maine in Ireland. He was born at Worcester on 1 August 1555, at 4 P.M. according t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Potassium Nitrate
Potassium nitrate is a chemical compound with the chemical formula . This alkali metal nitrate salt is also known as Indian saltpetre (large deposits of which were historically mined in India). It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or ''nitre'' in the UK). It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or ''saltpetre'' in the UK). Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (black powder). In processed meats, potassium nitrate reacts with hemoglobin and myoglobin generating a red color. Etymology Potassium nitrate, because of its early and global use and production, has many names. Hebrew and Egyptian words for it had the consonan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desire ...

Wawel
The Wawel Royal Castle (; ''Zamek Królewski na Wawelu'') and the Wawel Hill on which it sits constitute the most historically and culturally significant site in Poland. A fortified residency on the Vistula River in Kraków, it was established on the orders of King Casimir III the Great and enlarged over the centuries into a number of structures around an Italian-styled courtyard. It represents nearly all European architectural styles of the Medieval, Renaissance and Baroque periods. The castle is part of a fortified architectural complex erected atop a limestone outcrop on the left bank of the Vistula River, at an altitude of 228 metres above sea level.Dr. Jan Urban, "Geological foundation of Kraków"retrieved from the Internet Archive, May 21, 2008 The complex consists of numerous buildings of great historical and national importance, including the Wawel Cathedral where Polish monarchs were crowned and buried.

Determined to unify Christendom, he initiated the Long Turkish War (1593–1606) with the Ottoman Empire.

John Dee
John Dee (13 July 1527 – 1608 or 1609) was an English mathematician, astronomer, astrologer, teacher, occultist, and alchemist. He was the court astronomer for, and advisor to, Elizabeth I, and spent much of his time on alchemy, divination, and Hermetic philosophy. As an antiquarian, he had one of the largest libraries in England at the time. As a political advisor, he advocated the foundation of English colonies in the New World to form a " British Empire", a term he is credited with coining. Dee eventually left Elizabeth's service and went on a quest for additional knowledge in the deeper realms of the occult and supernatural. He aligned himself with several individuals who may have been charlatans, travelled through Europe and was accused of spying for the English crown. Upon his return to England, he found his home and library vandalised. He eventually returned to the Queen's service, but was turned away when she was succeeded by James I. He died in poverty in Lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Blac ...
