The Greek poet Hesiod is one of our best sources for information about Hekate. In his Theogony, Hesiod claims that Hekate was the daughter of Perses and Asteria. Furthermore, the poet includes a long and detailed description of the significance of this goddess in his poem:
"...Hekate, whom Zeus
honored above all others; he gave her dazzling gifts,
a share of the earth and a share of the barren sea.
She was given a place of honor in the starry sky,
and among the deathless gods her rank is high.
For even now, when a mortal propitiates the gods
and, following custom, sacrifices well-chosen victims,
he invokes Hekate, and if she receives his prayers
with favor, then honor goes to him with great ease,
and he is given blessings, because she has power
and a share in all the rights once granted
to the offspring of Ouranos and Gaia."
(Hesiod, Theogony, 411-422)
And there is much more to this passage of the Theogony. In essence, the poem states that Hekate had a great deal of power to help those she favored. However, it is important to remember that as a chthonian goddess, she also had the ability to punish. Indeed, this is where Hekate's role as a goddess of magic comes into play. In myth, for example, the sorceress Medea called upon the goddess for assistance in casting her dark spells.
Hekate was also associated with crossroads in mythology and legend, for it was believed that these areas were important in magical rituals.
In Roman mythology, Hekate was known as Trivia (the goddess of crossroads).
