Mermaids

Everything started when goddess Atagartis accidentally killed her humand lover and out of shame transformed herself into a mermaid  Mermaids are sometimes associated with perilous events such as floods, storms, shipwrecks and drownings. In other folk traditions (or sometimes within the same tradition), they can be benevolent or beneficent, bestowing boons or falling in love with humans.The male equivalent of the mermaid is the merman, also a familiar figure in folklore and heraldry. Although traditions about and sightings of mermen are less common than those of mermaids, they are generally assumed to co-exist with their female counterparts.Mermaids have been a popular subject of art and literature in recent centuries, such as in Hans Christian Andersen's well-known fairy tale "The Little Mermaid" (1836). They have subsequently been depicted in operas, paintings, books, films and comics.

Lernaean Hydra or Hydra of Lerna

 Hydra of Lerna more often known simply as the Hydra, was aserpentine water monster in Greek and Roman mythology. Its lair was the lake of Lerna in the Argolid, which was also the site of the myth of the Danaids. Lerna was reputed to be an entrance to the Underworld and archaeology has established it as a sacred site older than Mycenaean Argos. In the canonical Hydra myth, the monster is killed by Heracles, using sword and fire, as the second of his Twelve Labors.The Hydra was the offspring of Typhon and Echidna. It possessed many heads,for every head that was cut down it grew two more. Also one of its heads was inmortal.Additionaly,the Hydra had poisonous breath and blood so virulent that even its scent was deadly.

The Hydra guards the entrance to the Underworld and from the murky swamps of the Lake of Lerna the monstrous serpent would rise and terrorize the city. The Hydra was finally killed by Hercules during his second labor.

Ares

Ares is the Greek god of war. He is one of the Twelve Olympians, and the son of Zeus andHera. In Greek literature, he often represents the physical or violent and untamed aspect of war, in contrast to his sister the armored Athena, whose functions as a goddess of intelligence include military strategy and generalship.

The Greeks were ambivalent toward Ares: although he embodied the physical valor necessary for success in war, he was a dangerous force, "overwhelming, insatiable in battle, destructive, and man-slaughtering." His sons Fear (Phobos) and Terror(Deimos) and his lover, or sister, Discord (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 losing side, while Athena, often depicted in Greek art as holding Nike (Victory) in her hand, favored the triumphant Greeks.

Ares plays a relatively limited role in Greek mythology as represented in literary narratives, though his numerous love affairs and abundant offspring are often alluded to.When Ares does appear in myths, he typically faces humiliation. 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 husband's clever device.

The counterpart of Ares among the Roman gods is Mars, who as a father of the Roman people was given a more important and dignified place in ancient Roman  as a guardian deity. During the Hellenization of Latin literature, the myths of Ares werereinterpreted 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.

Athena

 Athena was the Greek virgin goddess of reason, intelligent activity, arts and literature. She was the daughter of Zeus; her birth is unique in that she did not have a mother. Instead, she sprang full grown and clad in armour from Zeus' forehead.

She was fierce and brave in battle; however, she only took part in wars that defended the state and home from outside enemies. She was the patron of the city, handcraft, and agriculture. She invented the bridle, which permitted man to tame horses, the trumpet, the flute, the pot, the rake, the plow, the yoke, the ship, and the chariot. She was the embodiment of wisdom, reason, and purity. She was Zeus' favourite child and was allowed to use his weapons including his thunderbolt. Her holy tree was the olive tree and she was often symbolised as an owl.

She became the patron goddess of Athens after winning a contest against Poseidon by offering the olive tree to the Athenians. It is evident that Athena and Athens derive from the same root; Athens (or Athenae) is in plural form, because it represents the sisterhood of the goddess that existed there. Similarly, Athena was called Mykene in the city of Mycenae (also a plural after the respective sisterhood), and Thebe in the city of Thebes (or Thebae, both plural forms).

Athena is the goddess of wisdom, courage, inspiration, civilization, law and justice, mathematics, olive cultivation, strength, war strategy, the arts, crafts, and skill in ancient Greek religion and mythology. Minerva is the Roman goddess identified with Athena. Athena is known for her calm temperament, as she moves slowly to anger. She is noted to have only fought for just reasons, and would not fight without a purpose.

Athena is portrayed as a shrewd companion of heroes and is the patron goddess of heroic endeavour. She is the virgin patroness of Athens. The Athenians founded the Parthenon on the Acropolis of her namesake city, Athens (Athena Parthenos), in her honour.

Veneration of Athena was so persistent that archaic myths about her were recast to adapt to cultural changes.In her role as a protector of the city (polis), many people throughout the Greek world worshipped Athena as Athena Polias (Ἀθηνᾶ Πολιάς "Athena of the city"). While the city of Athens and the goddess Athena essentially bear the same name (Athena the goddess, Athenaithe city), it is not known which of the two words is derived from the other.
