In Greek mythology, Phthonus (/ˈθoʊnəs/; Ancient Greek: Φθόνος Phthónos), or sometimes Zelus, was the personification of jealousy and envy, most prominently in matters of romance. In Nonnus's Dionysiaca, he is by proxy the cause of Semele's death, having informed Hera of Zeus's affair with the princess.
Hera was goddess of marriage and childbirth. Since Hera's husband was Zeus, king not only of gods, but of philanderers, Hera spent a lot of time in Greek mythology angry with Zeus. So Hera is described as jealous and quarrelsome.
When Athena saw that Arachne had not only insulted the gods but done so with a work far more beautiful than Athena's own, she was enraged. She ripped Arachne's work to shreds and hit her on the head three times.

Aphrodite's manipulative character is most apparent in the story of Helen, queen of Sparta, whom she offered as her bribe in the Judgment of Paris, inciting ten years of dreadful war at Troy.
Diomedes in the Iliad
In Iliad 5 Diomedes grazes Aphrodite's hand with his spear as she carries her unconscious son Aeneas away from the battlefield (Il. 5.330-351), and later he debilitates a much more formidable god, namely Ares (Il. 5.846-867).
Psyche was a young princess from Sicily, famous for her extraordinary beauty. According to legend, she was even more beautiful than Aphrodite, the goddess of beauty.
While that approach has certainly yielded important information on gender dynamics in late-Classical Greece, it tends to overlook the fact that though this Aphrodite is female, she is also divine.

In fact, Athena was jealous of Medusa's beauty and lustrous hair. Poseidon ravaged her and took what she held dearly, her purity. Athena, outraged by this incident, cursed Medusa and turned her wonderful hair into venomous snakes, her beautiful face turned so ugly that any man who gazed upon would turn to stone.
Medusa and Poseidon engaged in a love affair and would have two children together, but not before Athena discovered the illicit affair. When Athena discovered the affair, she was enraged and immediately cursed Medusa by taking away her beauty.
She never had a true lover or someone to hug and hold her; all she had was her loving mother, caring father and most of all her brothers and sisters. For some very strange reason it was hopeless that she would fall in love; Hephaestus tried once, yet failed. Athena was well known for giving advice/mentoring heroes.
Minthe was a Naiad nymph of the river Cocytus who became mistress to Persephone's husband Hades. Persephone was not slow to notice, and in jealousy she trampled the nymph, killing her and turning her into a mint plant.
