The Twelve Olympians, also known as the Dodekatheon , in Greek mythology, were the principal gods of the
Greek pantheon, residing atop Mount Olympus. The first ancient reference of religious ceremonies for them is
found in the Homeric Hymn to Hermes. The classical scheme of the Twelve Olympians (the Canonical Twelve of art
and poetry) comprises the following gods: Zeus, Hera, Poseidon, Demeter, Ares, Hermes, Hephaestus,
Aphrodite, Athena, Apollo, Artemis, Hestia. The respective Roman scheme comprises the following gods: Jupiter,
Juno, Neptune, Ceres, Mars, Mercury, Vulcan, Venus, Minerva, Apollo, Diana and Vesta.
There was, however, a great deal of fluidity when it came to who was counted among their number in antiquity.
Around 400 BC Herodorus included in his Dodekatheon the following deities: Zeus, Poseidon, Hera, Athena,
Hermes, Apollo, Alpheus, Cronus, Rhea and the Charites. Wilamowitz agrees with Herodorus' version of the
Twelve.
Herodotus includes Heracles as one of the Twelve. Lucian also includes Heracles and Asclepius as members of
the Twelve, without explaining which two had to give way for them. At Kos, Heracles and Dionysus are added to the
Twelve, and Ares and Hephaestus are left behind. However,Pindar, Apollodorus, and Herodorus disagree with this.
For them Heracles is not one of the Twelve Gods, but the one who established their cult.
Plato connected the Twelve Olympians with the twelve months, and proposed that the final month be devoted to
rites in honor of Pluto and the spirits of the dead, implying that he considered Hades to be one of the Twelve.
Hades is phased out in later groupings due to his chthonic associations. In Phaedrus Plato aligns the Twelve with
the Zodiac and would exclude Hestia from their rank.[10]
Hestia is sometimes displaced by Dionysus. Hebe, Helios and Persephone are other important gods, goddesses,
which are sometimes included in a group of twelve. Eros is often depicted alongside the other twelve, especially his
mother Aphrodite, but is rarely considered one of the Olympians.
The Twelve Olympians gained their supremacy in the world of gods after Zeus led his siblings to victory in war with
the Titans. Zeus, Hera, Poseidon, Demeter, Hestia, and Hades were siblings. Ares, Hermes, Hephaestus,
Aphrodite, Athena, Apollo, Artemis, the Charites, Heracles, Dionysus, Hebe, and Persephone were children of
Zeus. Although some versions of the myths state that Hephaestus was born of Hera alone, and that Aphrodite was
born of Ouranos.

Notes
According to an alternate version of her birth, Aphrodite was born of Ouranos — after Cronus threw his castrated genitals into the sea.
This supports the etymology of her name, "foam-born". As such, Aphrodite would belong to a generation above, or equal to, Zeus and
his siblings.
