Agathodaemon (alchemist)
Agathodaemon (, ''Agathodaímōn''; ) was an alchemist in late Roman Egypt, known only from fragments quoted in medieval alchemical treatises, chiefly the ''Anepigraphos'', which refer to works of his believed to be from the 3rd century.Brian P. Copenhaver, ''Hermetica: the Greek Corpus Hermeticum and the Latin Asclepius in a new English translation, with notes and introduction''. Cambridge University Press, 1992. He is primarily remembered for his various descriptions of elements and minerals, most particularly his descriptions of a method of producing silver, and of a substance he had created, which he called a 'fiery poison', and which, judging by his account, was arsenic trioxide, a highly toxic amphoteric oxide. He described the 'fiery poison' as being formed when a certain mineral (most probably realgar or orpiment) was fused with natron (naturally occurring sodium carbonate), and that dissolved in water to give a clear solution. He also wrote of how, when he placed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...

Year Of Birth Unknown
A year is a unit of time based on how long it takes the Earth to orbit the Sun. In scientific use, the tropical year (approximately 365 solar days, 5 hours, 48 minutes, 45 seconds) and the sidereal year (about 20 minutes longer) are more exact. The modern calendar year, as reckoned according to the Gregorian calendar, approximates the tropical year by using a system of leap years. The term 'year' is also used to indicate other periods of roughly similar duration, such as the lunar year (a roughly 354-day cycle of twelve of the Moon's phasessee lunar calendar), as well as periods loosely associated with the calendar or astronomical year, such as the seasonal year, the fiscal year, the academic year, etc. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ancient Alchemists
Ancient history is a time period from the History of writing, beginning of writing and recorded human history through late antiquity. The span of recorded history is roughly 5,000 years, beginning with the development of Sumerian language, Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BCAD 500, ending with the Early Muslim conquests, expansion of Islam in late antiquity. The three-age system periodises ancient history into the Stone Age, the Bronze Age, and the Iron Age, with recorded history generally considered to begin with the Bronze Age. The start and end of the three ages vary between world regions. In many regions the Bronze Age is generally considered to begin a few centuries prior to 3000 BC, while the end of the Iron Age varies from the early first millennium BC in some regions to the late first millennium AD in others. During the time period of ancient history, the world population was Exponential growth, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agathodaemon
Agathos Daimon (, , ) originally was a lesser deity (''daemon'') of classical ancient Greek religion and Graeco-Egyptian religion. In his original Greek form, he served as a household god, to whom, along with Zeus Soter, libations were made after a meal. In later Ptolemaic antiquity he took on two partially distinct roles; one as the Agathos Daimon a prominent serpentine civic god, who served as the special protector of Alexandria. The other as a genus of serpentine household gods, the Agathoi Daimones, individual protectors of the homes in which they were worshipped. Early history Agathos Daimon was attested in domestic context in Greece as early as the fifth century BC, and yet he was typically not represented there in the form of a snake, as opposed to in Alexandria, where he was abundantly so represented. : "His origin in Alexandria is a matter of dispute, with two conflicting views either painting Agathos Daimon as a Greek cultural importation later identified with Ser ...

Zosimos Of Panopolis
Zosimos of Panopolis (; also known by the Latin name Zosimus Alchemista, i.e. "Zosimus the Alchemist") was an alchemist and Gnostic mystic. He was born in Panopolis (present day Akhmim, in the south of Roman Egypt), and likely flourished ca. 300 AD. He wrote the oldest known books on alchemy, which he called "Cheirokmeta," using the Greek word for "things made by hand." Pieces of this work survive in the original Greek language and in translations into Syriac or Arabic. He is one of about 40 authors represented in a compendium of alchemical writings that was probably put together in Constantinople in the 7th or 8th century AD, copies of which exist in manuscripts in Venice and Paris. Stephen of Alexandria is another. Arabic translations of texts by Zosimos were discovered in 1995 in a copy of the book ''Keys of Mercy and Secrets of Wisdom'' by Ibn Al-Hassan Ibn Ali Al-Tughra'i', a Persian alchemist. The translations were incomplete and seemingly non-verbatim. The famous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
