Ares
–
Ares is the Greek god of war. He is one of the Twelve Olympians, and the son of Zeus and his sons Phobos and Deimos and his lover, or sister, Enyo accompanied him on his war chariot. In the Iliad, his father Zeus tells him that he is the god most hateful to him, an association with Ares endows places and objects with a savage, dangerous, or militarized quality. His value as a war god is placed in doubt, during the Trojan War, Ares was on the side, while Athena, often depicted in Greek art as holding Nike in her hand. Ares plays a limited role in Greek mythology as represented in literary narratives, though his numerous love affairs. When Ares does appear in myths, he typically faces humiliation and he is well known as the lover of Aphrodite, the goddess of love, who was married to Hephaestus, god of craftsmanship. The most famous story related to Ares and Aphrodite shows them exposed to ridicule through the wronged husbands device. The counterpart of Ares among the Roman gods is Mars, who as a father of the Roman people was given a more important, during the Hellenization of Latin literature, the myths of Ares were reinterpreted by Roman writers under the name of Mars. Greek writers under Roman rule also recorded cult practices and beliefs pertaining to Mars under the name of Ares, thus in the classical tradition of later Western art and literature, the mythology of the two figures becomes virtually indistinguishable. The etymology of the name Ares is traditionally connected with the Greek word ἀρή, there may also be a connection with the Roman god of war Mars, via hypothetical Proto-Indo-European *M̥rēs, compare Ancient Greek μάρναμαι, I fight, I battle. Walter Burkert notes that Ares is apparently an ancient abstract noun meaning throng of battle, R. S. P. Beekes has suggested a Pre-Greek origin of the name. The earliest attested form of the name is the Mycenaean Greek

Mars (mythology)
–
In ancient Roman religion and myth, Mars was the god of war and also an agricultural guardian, a combination characteristic of early Rome. He was second in only to Jupiter and he was the most prominent of the military gods in the religion of the Roman army. Most of his festivals were held in March, the named for him, and in October. Under the influence of Greek culture, Mars was identified with the Greek god Ares, whose myths were reinterpreted in Roman literature and art under the name of Mars. But the character and dignity of Mars differed in fundamental ways from that of his Greek counterpart, Mars was a part of the Archaic Triad along with Jupiter and Quirinus, the latter of whom as a guardian of the Roman people had no Greek equivalent. Mars altar in the Campus Martius, the area of Rome that took its name from him, was supposed to have been dedicated by Numa, the peace-loving semi-legendary second king of Rome. Although Ares was viewed primarily as a destructive and destabilizing force, Mars represented military power as a way to secure peace, in the mythic genealogy and founding myths of Rome, Mars was the father of Romulus and Remus with Rhea Silvia. Like Ares who was the son of Zeus and Hera, Mars is usually considered to be the son of Jupiter, however, in a version of his birth given by Ovid, he was the son of Juno alone. Jupiter had usurped the mothers function when he gave birth to Minerva directly from his forehead, to restore the balance, Flora obtained a magic flower and tested it on a heifer who became fecund at once. She then plucked a flower ritually using her thumb, touched Junos belly, Juno withdrew to Thrace and the shore of Marmara for the birth. Ovid tells this story in the Fasti, his poetic work on the Roman calendar. In the earliest Roman calendar, March was the first month, Ovid is the only source for the story. The consort of Mars was Nerio or Nerine, Valor and she represents the vital force, power and majesty of Mars. Her name was regarded as Sabine in origin and is equivalent to Latin virtus, in the early 3rd century BC, the comic playwright Plautus has a reference to Mars greeting Nerio, his wife. A source from late antiquity says that Mars and Nerine were celebrated together at a festival held on March 23, in the later Roman Empire, Nerine came to be identified with Minerva. Nerio probably originates as a personification of Mars power, as such abstractions in Latin are generally feminine. Her name appears with that of Mars in an archaic prayer invoking a series of abstract qualities, the influence of Greek mythology and its anthropomorphic gods may have caused Roman writers to treat these pairs as marriages. The union of Venus and Mars held greater appeal for poets and philosophers, in Greek myth, the adultery of Ares and Aphrodite had been exposed to ridicule when her husband Hephaestus caught them in the act by means of a magical snare

Etruscan mythology
–
Etruscan religion and mythology were partly incorporated into classical Roman culture, including the Roman pantheon. However, in the last years of the Roman Republic the religion began to fall out of favor and was satirized by such public figures as Marcus Tullius Cicero. The Julio-Claudians, especially Claudius, who claimed a remote Etruscan descent, maintained a knowledge of the language and religion for a time longer. A number of works in the Etruscan language survived until the middle of the first millennium AD, but were destroyed by the ravages of time, decree of the Roman Senate. Around the mun or muni, or tombs, were the man or mani, in iconography after the 5th century BC, the deceased are shown traveling to the underworld. In several instances of Etruscan art, such as in the François Tomb in Vulci, a god was called an ais, which in the plural is aisar. The abode of a god was a fanu or luth, a place, such as a favi. There, one would need to make a fler, or offering, three layers of deities are portrayed in Etruscan art. Ruling over them were higher deities that seem to reflect the Indo-European system, Tin or Tinia, the sky, Uni his wife, and Cel, as a third layer, the Greek gods were adopted by the Etruscan system during the Etruscan Orientalizing Period of 750/700-600 BC. Examples are Aritimi, Menrva, and Pacha, and over time the primary trinity became Tinia, Uni, the Etruscans believed in intimate contact with divinity. They did nothing without proper consultation with the gods and signs from them and these practices were taken over in total by the Romans. The Etruscan scriptures were a corpus of texts termed the Etrusca Disciplina and this name appears in Valerius Maximus, and Marcus Tullius Cicero refers to a disciplina in his writings on the subject. These works did not present prophecies or scriptures in the ordinary sense, the Etruscans appear to have had no systematic ethics or religion and no great visions. The Etruscans accepted the inscrutability of their gods wills and they did not attempt to rationalize or explain divine actions or formulate any doctrines of the gods intentions. These revelations may not be understandable and may not be pleasant or easy. He then quipped, regarding divination from the singing of frogs, and yet they do have by nature some faculty of premonition, clear enough of itself, but too dark for human comprehension. Divinatory inquiries according to discipline were conducted by priests whom the Romans called haruspices or sacerdotes, the Etruscans, as evidenced by the inscriptions, used several words, capen, maru, eisnev, hatrencu. They called the art of haruspicy zich nethsrac, a special magistrate, the cechase, looked after the cecha or rath, sacred things

War
–
War is a state of armed conflict between societies. It is generally characterized by extreme aggression, destruction, and mortality, an absence of war is usually called peace. Warfare refers to the activities and characteristics of types of war. Total war is warfare that is not restricted to legitimate military targets. While some scholars see war as a universal and ancestral aspect of human nature, as concerns a belligerents losses in proportion to its prewar population, the most destructive war in modern history may have been the Paraguayan War. In 2013 war resulted in 31,000 deaths, down from 72,000 deaths in 1990, in 2003, Richard Smalley identified war as the sixth biggest problem facing humanity for the next fifty years. Another byproduct of some wars is the prevalence of propaganda by some or all parties in the conflict, the word is related to the Old Saxon werran, Old High German werran, and the German verwirren, meaning “to confuse”, “to perplex”, and “to bring into confusion”. In German, the equivalent is Krieg, the Spanish, Portuguese, the scholarly study of war is sometimes called polemology, from the Greek polemos, meaning war, and -logy, meaning the study of. Studies of war by military theorists throughout military history have sought to identify the philosophy of war, asymmetric warfare is a conflict between two populations of drastically different levels of military capability or size. Biological warfare, or germ warfare, is the use of weaponized biological toxins or infectious agents such as bacteria, viruses, chemical warfare involves the use of weaponized chemicals in combat. Poison gas as a weapon was principally used during World War I. Civil war is a war between forces belonging to the nation or political entity. Conventional warfare is declared war between states in which nuclear, biological, or chemical weapons are not used or see limited deployment, cyberwarfare involves the actions by a nation-state or international organization to attack and attempt to damage another nations information systems. Information warfare is the application of force on a large scale against information assets and systems, against the computers. Nuclear warfare is warfare in which weapons are the primary, or a major. War of aggression is a war for conquest or gain rather than self-defense, the earliest recorded evidence of war belongs to the Mesolithic cemetery Site 117, which has been determined to be approximately 14,000 years old. About forty-five percent of the skeletons there displayed signs of violent death, since the rise of the state some 5,000 years ago, military activity has occurred over much of the globe. The advent of gunpowder and the acceleration of technological advances led to modern warfare

Helmet
–
A helmet is a form of protective gear worn to protect the head from injuries. More specifically, a helmet aids the skull in protecting the human brain, ceremonial or symbolic helmets without protective function are sometimes used. The oldest known use of helmets was by Assyrian soldiers in 900 BC, soldiers still wear helmets, now often made from lightweight plastic materials. In civilian life, helmets are used for activities and sports, dangerous work activities. Since the 1990s, most helmets are made from resin or plastic, the word helmet is diminutive from helm, a medieval word for protective combat headgear. The Medieval great helm covers the head and often is accompanied with camail protecting throat. Originally a helmet was a helm which covered the head only partly, all helmets attempt to protect the users head by absorbing mechanical energy and protecting against penetration. Their structure and protective capacity are altered in high-energy impacts, beside their energy-absorption capability, their volume and weight are also important issues, since higher volume and weight increase the injury risk for the users head and neck. Anatomical helmets adapted to the head structure were invented by neurosurgeons at the end of the 20th century. Helmets used for different purposes have different designs, for example, a bicycle helmet must protect against blunt impact forces from the wearers head striking the road. A helmet designed for rock climbing must protect against heavy impact, sports helmets may have an integrated metal face protector. Baseball batting helmets have an expanded protection over the ear, which protects the jaw from injury, motorcycle helmets often have flip-down face screens for rain and wind protection, and they may also have projecting visors to protect the eyes from glare. Hard hats for construction workers are mainly to protect the wearer from falling objects such as tools. Helmets for riot police often have flip-down clear visors and thick padding to protect the back of the neck, Modern firefighters helmets protect the face and back of the head against impact, fires and electricity, and can include masks, communication systems, and other accessories. Welding helmets protect the eyes and face and neck from flash burn, ultraviolet light, sparks and heat. They have a window, called a lens shade, through which the welder looks at the weld. People with some medical conditions must wear a helmet to protect the brain, due to a gap in the braincase, mixed martial arts helmets have ear pads to prevent serious injuries to the athletes, who do not usually endure such force to the ears. Crash helmets for F1 racing drivers, their design and construction have evolved enormously, nevertheless, head and neck trauma remains the greatest single injury risk to drivers

Fire
–
Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition, at a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen, if hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame, Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe, the positive effects of fire include stimulating growth and maintaining various ecological systems. The negative effects of fire hazard to life and property, atmospheric pollution. If fire removes protective vegetation, heavy rainfall may lead to an increase in soil erosion by water and this is commonly called the fire tetrahedron. Fire cannot exist without all of elements in place and in the right proportions. For example, a liquid will start burning only if the fuel. Some fuel-oxygen mixes may require a catalyst, a substance that is not consumed, when added, in any chemical reaction during combustion, but which enables the reactants to combust more readily. Without gravity, a fire rapidly surrounds itself with its own products and non-oxidizing gases from the air. Because of this, the risk of fire in a spacecraft is small when it is coasting in inertial flight, of course, this does not apply if oxygen is supplied to the fire by some process other than thermal convection. Fire can be extinguished by removing any one of the elements of the fire tetrahedron, consider a natural gas flame, such as from a stovetop burner. In contrast, fire is intensified by increasing the rate of combustion. In many cases, such as the burning of organic matter, for wood, or the incomplete combustion of gas. This light has a continuous spectrum, complete combustion of gas has a dim blue color due to the emission of single-wavelength radiation from various electron transitions in the excited molecules formed in the flame. Usually oxygen is involved, but hydrogen burning in chlorine produces a flame
