History Of Chemical Warfare
Chemical weapons have been a part of warfare in most societies, although their use has been particularly controversial since the 20th century. Ancient and medieval times Ancient Greek myths about Heracles poisoning his arrows with the venom of the Hydra monster are the earliest references to toxic weapons in western literature. Homer's epics, the ''Iliad'' and the ''Odyssey'', allude to poisoned arrows used by both sides in the legendary Trojan War (Bronze Age Greece).Adrienne Mayor, "Greek Fire, Poison Arrows & Scorpion Bombs: Biological and Chemical Warfare in the Ancient World" Overlook-Duckworth, 2003, rev ed with new Introduction 2008 Some of the earliest surviving references to toxic warfare appear in the Indian epics ''Ramayana'' and ''Mahabharata.'' The "Laws of Manu," a Hindu treatise on statecraft (c. 400 BC) forbids the use of poison and fire arrows, but advises poisoning food and water. Kautilya's "Arthashastra", a statecraft manual of the same era, contains hundreds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Weapons
A chemical weapon (CW) is a specialized Ammunition, munition that uses chemicals chemical engineering, formulated to inflict death or harm on humans. According to the Organisation for the Prohibition of Chemical Weapons (OPCW), this can be any chemical compound intended as a weapon "or its Precursor (chemistry), precursor that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action. Munitions or other delivery devices designed to deliver chemical weapons, whether filled or unfilled, are also considered weapons themselves." Chemical weapons are classified as weapons of mass destruction (WMD), though they are distinct from nuclear weapons, biological warfare, biological weapons, and radiological weapons. All may be used in warfare and are known by the military acronym NBC (for nuclear, biological, and chemical warfare). Weapons of mass destruction are distinct from conventional weapons, which are primarily effective due to their explos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sun Tzu
Sun Tzu ( ; zh, t=孫子, s=孙子, first= t, p=Sūnzǐ) was a Chinese military general, strategist, philosopher, and writer who lived during the Eastern Zhou period of 771 to 256 BCE. Sun Tzu is traditionally credited as the author of ''The Art of War'', an influential work of military strategy that has affected both Western and East Asian philosophy and military thinking. Sun Tzu is revered in Chinese and East Asian culture as a legendary historical and military figure. His birth name was Sun Wu ( zh, t=孫武, s=孙武, first=t) and he was known outside of his family by his courtesy name Changqing ( zh, t=長卿). The name ''Sun Tzu'' by which he is more popularly known is an honorific which means "Master Sun". Sun Tzu's historicity is uncertain. The Han dynasty historian Sima Qian and other traditional Chinese historians placed him as a minister to King Helü of Wu and dated his lifetime to 544–496 BCE. Modern scholars accepting his historicity place the extant text of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman–Persian Wars
The Roman–Persian Wars, also known as the Roman–Iranian Wars, were a series of conflicts between states of the Greco-Roman world and two successive Iranian empires: the Parthian and the Sasanian. Battles between the Parthian Empire and the Roman Republic began in 54 BC; wars began under the late Republic, and continued through the Roman (later Byzantine) and Sasanian empires. A plethora of vassal kingdoms and allied nomadic nations in the form of buffer states and proxies also played a role. The wars were ended by the early Muslim conquests, which led to the fall of the Sasanian Empire and huge territorial losses for the Byzantine Empire, shortly after the end of the last war between them. Although warfare between the Romans and Persians continued over seven centuries, the frontier, aside from shifts in the north, remained largely stable. A game of tug of war ensued: towns, fortifications, and provinces were continually sacked, captured, destroyed, and traded. Neithe ...

Kirrha
Cirrha or Kirra ( grc, Κίρρα) was a town in ancient Phocis on the coast, which served as the harbour of Delphi. Pausanias erroneously supposes that Cirrha was a later name of the Homeric Crissa. They were two separate towns, with interlinked histories. Crissa was more ancient than Cirrha, and was situated inland a little southwest of Delphi, at the southern end of a projecting spur of Mount Parnassus. Crissa gave name to the Crissaean Gulf, and its ruins may still be seen at a short distance from the modern village of Chrisso. Cirrha was built subsequently at the head of the gulf, and rose into a town from being the port of Crissa. This is in accordance with what we find in the history of other Grecian states. The original town is built upon a height at some distance from the sea, to secure it against hostile attacks, especially by sea; but in course of time, when property has become more secure, and the town itself has grown in power, a second place springs up on that part o ...

River Pleistos
The Pleistos ( el, Πλείστος, grc, Πλεῖστος, la, Pleistus) is a river in central Greece. It drains the Pleistos valley, named after it, a relatively recent rift valley north of the Gulf of Corinth, and parallel to it. They have the same geologic causes. Being situated in karst topography, much of the river runs or seeps through underground channels. The surface stream is intermittent. However, the limestone riverbed reflecting the light gives the appearance of a stream of water. The semi-arid valley floor, too inaccessible for urban development, is eminently suitable for dendriculture. Extensive olive groves, knicknamed the "sea of olives," have been in place since prehistoric times. The floor is flanked by precipitous elevations, notably a scarp on the north side. The primary access road to the valley runs on the side of the north scarp throughout its entire length. Near the lower valley the road intersects the site of ancient Delphi. Oracular temples have exis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hellebore
Commonly known as hellebores (), the Eurasian genus ''Helleborus'' consists of approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. Despite names such as "winter rose", "Christmas rose" and "Lenten rose", hellebores are not closely related to the rose family (Rosaceae). Many hellebore species are poisonous. Description The flowers have five petal-like sepals surrounding a ring of small, cup-like nectaries which are actually petals modified to hold nectar. The sepals do not fall as petals would, but remain on the plant, sometimes for many months. Recent research in Spain suggests that the persistence of the sepals contributes to the development of the seeds. Taxonomy The genus was established by Carl Linnaeus in volume one of his ''Species Plantarum'' in 1753. The scientific name ''Helleborus'' could derive from the Ancient Greek word (), the common name for '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solon
Solon ( grc-gre, Σόλων; BC) was an Athenian statesman, constitutional lawmaker and poet. He is remembered particularly for his efforts to legislate against political, economic and moral decline in Archaic Athens.Aristotle ''Politics'' 1273b 35–1274a 21 His reforms failed in the short term, yet Solon is credited with having laid the foundations for Athenian democracy.Stanton, G. R. ''Athenian Politics c. 800–500 BC: A Sourcebook'', Routledge, London (1990), p. 76.E. Harris, ''A New Solution to the Riddle of the Seisachtheia'', in ''The Development of the Polis in Archaic Greece'', eds. L. Mitchell and P. Rhodes (Routledge 1997) 103 His constitutional reform also succeeded in overturning most laws established by Draco. Modern knowledge of Solon is limited by the fact that his works only survive in fragments and appear to feature interpolations by later authors and by the general paucity of documentary and archaeological evidence covering Athens in the early 6th cen ...

Sparta
Sparta ( Doric Greek: Σπάρτα, ''Spártā''; Attic Greek: Σπάρτη, ''Spártē'') was a prominent city-state in Laconia, in ancient Greece. In antiquity, the city-state was known as Lacedaemon (, ), while the name Sparta referred to its main settlement on the banks of the Eurotas River in Laconia, in south-eastern Peloponnese. Around 650 BC, it rose to become the dominant military land-power in ancient Greece. Given its military pre-eminence, Sparta was recognized as the leading force of the unified Greek military during the Greco-Persian Wars, in rivalry with the rising naval power of Athens. Sparta was the principal enemy of Athens during the Peloponnesian War (431–404 BC), from which it emerged victorious after the Battle of Aegospotami. The decisive Battle of Leuctra in 371 BC ended the Spartan hegemony, although the city-state maintained its political independence until its forced integration into the Achaean League in 192 BC. The city nevertheless ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Athens
Athens ( ; el, Αθήνα, Athína ; grc, Ἀθῆναι, Athênai (pl.) ) is both the capital and largest city of Greece. With a population close to four million, it is also the seventh largest city in the European Union. Athens dominates and is the capital of the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years and its earliest human presence beginning somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state. It was a centre for the arts, learning and philosophy, and the home of Plato's Academy and Aristotle's Lyceum. It is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political influence on the European continent—particularly Ancient Rome. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Gre ...

Peloponnesian War
The Peloponnesian War (431–404 BC) was an ancient Greek war fought between Athens and Sparta and their respective allies for the hegemony of the Greek world. The war remained undecided for a long time until the decisive intervention of the Persian Empire in support of Sparta. Led by Lysander, the Spartan fleet built with Persian subsidies finally defeated Athens and started a period of Spartan hegemony over Greece. Historians have traditionally divided the war into three phases. The first phase (431–421 BC) was named the Ten Years War, or the Archidamian War, after the Spartan king Archidamus II, who launched several invasions of Attica with the full hoplite army of the Peloponnesian League, the alliance network dominated by Sparta. However, the Long Walls of Athens rendered this strategy ineffective, while the superior navy of the Delian League (Athens' alliance) raided the Peloponnesian coast to trigger rebellions within Sparta. The precarious Peace of Nicias was si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III-V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are an essential dietary element in rats, ham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
