Ares (/ˈɛəriːz/Ancient Greek: Ἄρης, Árēs [árɛːs]) is the Greek god of war and courage. He is one of the Twelve Olympians, and the son of Zeus and Hera. The Greeks were ambivalent towards him. He embodies the physical valor necessary for success in war but can also personify sheer brutality and bloodlust, in contrast to his sister Athena, whose martial functions include military strategy and generalship. An association with Ares endows places, objects, and other deities with a savage, dangerous, or militarized quality.

Although Ares’ name shows his origins as Mycenaean, his reputation for savagery was thought by some to reflect his likely origins as a Thracian deity. Some cities in Greece and several in Asia Minor held annual festivals to bind and detain him as their protector. In parts of Asia Minor, he was an oracular deity. Still further away from Greece, the Scythians were said to ritually kill one in a hundred prisoners of war as an offering to their equivalent of Ares. The later belief that ancient Spartans had offered human sacrifice to Ares may owe more to mythical prehistory, misunderstandings, and reputation than to reality.

Though there are many literary allusions to Ares’ love affairs and children, he has a limited role in Greek mythology. When he does appear, he is often humiliated. In the Trojan WarAphrodite, protector of Troy, persuades Ares to take the Trojans’ side. The Trojans lose, while Ares’ sister Athena helps the Greeks to victory. Most famously, when the craftsman-god Hephaestus discovers his wife Aphrodite is having an affair with Ares, he traps the lovers in a net and exposes them to the ridicule of the other gods.

Ares’ nearest counterpart in Roman religion is Mars, who was given a more important and dignified place in ancient Roman religion as ancestral protector of the Roman people and state. During the Hellenization of Latin literature, the myths of Ares were reinterpreted by Roman writers under the name of Mars, and in later Western art and literature, the mythology of the two figures became virtually indistinguishable.

Names

The etymology of the name Ares is traditionally connected with the Greek word ἀρή (arē), the Ionic form of the Doric ἀρά (ara), “bane, ruin, curse, imprecation”.[1] Walter Burkert notes that “Ares is apparently an ancient abstract noun meaning throng of battle, war.”[2] R. S. P. Beekes has suggested a Pre-Greek origin of the name.[3] The earliest attested form of the name is the Mycenaean Greek 𐀀𐀩, a-re, written in the Linear B syllabic script.[4][5][6]

The adjectival epithetAreios (“warlike”) was frequently appended to the names of other gods when they took on a warrior aspect or became involved in warfare: Zeus AreiosAthena Areia, even Aphrodite Areia (“Aphrodite within Ares” or “feminine Ares”), who was warlike, fully armoured and armed, partnered with Athena in Sparta, and represented at Kythira‘s temple to Aphrodite Urania.[7] In the Iliad, the word ares is used as a common noun synonymous with “battle.”[2]

In the Classical period, Ares is given the epithet Enyalios, which seems to appear on the Mycenaean KN V 52 tablet as 𐀁𐀝𐀷𐀪𐀍, e-nu-wa-ri-jo.[8][9] Enyalios was sometimes identified with Ares and sometimes differentiated from him as another war god with separate cult, even in the same town; Burkert describes them as “doubles almost”.[10][11]
