She did not need to carry anything: as Persephone is a goddess, she could create or destroy anything she had need of.
There is no son of Poseidon and Persephone. Hades was the husband of Persephone and brother of Poseidon. Poseidon was brother to Hades and Zeus, and husband of Amphitrite.
It would depend on the problem, but Persephone was a goddess of curses and magic and the Furies themselves answered to her whims - as Queen of the Underworld, it was not done to cross her. Yet Persephone could be kind.
Many, for Persephone is daughter of Demeter and Zeus. Any child of her parents would be her sibling.
Persephone ate the pomegranates because she was hungry. Had she not been a goddess, she would have starved to death.
None who opposed the will of Persephone would live happily, as she and Hades were death deities, and her father Zeus would make them as miserable above as they would be below, as well, Persephone herself commanded the Furies of the Underworld, sometimes named as their mother.
i don't think they did worship persephone Any offerings to Persephone would have been made only during the autumn and winter and only alongside those made to Hades.
As Zeus is the father of Persephone, his brothers Hades and Poseidon are her uncles. Demeter, sister of Zeus, also has the same brothers. Also Demeter is Persephone's mother, its a massive love triangle between the whole family, So if hades and Persephone have kids, then there kids could fall in love with Persephone's mum or dad which would be hades brothers or sisters and it would be okay, its really disgusting actually.
At one time she aided Demeter in her search for Persephone, when Hecate found her she stayed in the Underworld with her as her companion.
Persephone (the Greek goddess of fertility, spring, and Queen of the Underworld) is the daughter of Demeter (goddess of agriculture) and Zeus (god of the skies). So her mother would be Demeter. In Roman terms, Persephone (Proserpina) would be daughter of Ceres, the Roman version of Demeter.
I would imagine Persephone's mother and father gave her her name. She is also known as Kore or Cora in her maiden form.
Persephone is a very compassionate Goddess, she does not do harm to people. The only reason she ever would is if they crossed her in a negative manner.
I would say Hades' weakness is Persephone.
