Hades was angered by this and kidnapped Persephone. Demeter was very angered by this and caused a doom on earth.

Zeus had to intervene and make Hades return Persephone to her mother. However, Persephone, who actually belonged to earth, had to spend one third of the year with Hades in the Underworld as she had consumed some pomegranate seed during her brief stay.

Once Aidoneus learned of Peirithous' plan, he killed Peirithous and confined Theseus. Plutarch had essentially utilised several aspects of Hades' mythology and turned them into a historical account.

This is later supported by Statius Roman epic C1st A. Justin Martyr 2nd century AD alludes to children of Pluto, but neither names nor enumerates them.

Apparently Vereratio is a reference to Makaria, "Blessedness," who was a daughter of Hades, according to the Suda. Judging from the earlier religions it's evident that Persephone was not in fact infertile and its highly probable that she was the mother of Macaria.

It's believed that it's entirely possible that there were more children attributed to Hades and Persephone that were later syncretised to become children of Zeus.

In the story of Zagreus, its mentioned that the father appeared as a snake A creature associated with Hades and the Underworld , the father is written into this myth in code, not outright, as Hades.

A few lines are added to reference back to Zeus, but the deeper symbolism points to Hades. The way that this myth was written was done in a way so that people who worshipped her as a child of Hades were free to do so; but also those who believed that she was a child of Zeus had a way of explaining their beliefs.

Another myth tells of Hades' involvement with Asclepius, a mortal son of Apollo who was a gifted healer and the world's first doctor. Asclepius was so gifted he was able to give mortals longer lives by curing plagues and showing them how to take care of themselves.

Asclepius brought people back from the brink of death many times. Eventually though Asclepius started to bring people back from the dead for hefty sums of money.

It was with this feat that Hades lost his temper and stormed up to Mount Olympus demanding that Asclepius pay the price for openly mocking death.

Zeus appeased Hades by personally striking down Asclepius with a thunderbolt. Apollo, enraged at the death of his son, killed the younger generations of Cyclopes that forged the bolt.

Enraged at Apollo's defiance Zeus forced him to serve a mortal king for a year as punishment. Asclepius was later deified as the god of healing.

One of the few other myths Hades played a major part in was the myth of Sisyphus. Sisyphus was a clever and charismatic king who feared death and made up his mind to find a way to evade Hades.

Sisyphus trapped Thanatos when he came to reap his soul and though Thanatos escaped and Hades would drag Sisyphus to the Underworld anyway Sisyphus had told his wife not to bury him with fare and so his ghost was sent back to ask for his last rites but Sisyphus instead remained in the world of the living as an undead, content to live forever in life rather than go to the Underworld.

However, Hades discovered Sisyphus' ruse and came to collect him. Hades was so angry at Sisyphus for holding the natural order hostage that he arranged a special punishment for him.

Hades put Sisyphus on the edge the pits of Tartarus but told Sisyphus that his schemes would be overlooked and he had a chance to go to the paradise of Elysium if and only if he could roll a large boulder up a hill; Sisyphus quickly agreed fearing the punishments of Tartarus and tried to push the boulder up the hill but it fell, frantically he tried again and it fell.
