According to Homer,
Dia had sex with
Zeus, who was disguised as a stallion, and gave birth to Pirithous; a
folk etymology derived Pirithous' name from peritheein (περιθεῖν, 'to run around'), because that was what Zeus did to seduce Dia.
His best friend was
Theseus. In the Iliad I, Nestor numbers Pirithous and Theseus "of heroic fame" among an earlier generation of heroes of his youth, "the strongest men that Earth has bred, the strongest men against the strongest enemies, a savage mountain-dwelling tribe whom they utterly destroyed." No trace of such an oral tradition, which Homer's listeners would have recognized in Nestor's allusion, survived in literary epic.
In disjointed episodes that have survived, Pirithous had heard rumors about Theseus' courage and strength in battle but he wanted proof. He rustled Theseus' herd of cattle from
Marathon, and Theseus set out to pursue him. Pirithous took up arms and the pair met, then became so impressed with each other's gracefulness, beauty and courage they took an oath of friendship.[4] They were among the company of heroes that hunted the
Calydonian Boar, another mythic theme that was already well known to Homer's listeners.
Centauromachy
Later, Pirithous was set to marry
Hippodamia, their offspring being
Polypoetes. The
centaurs were guests at the party, but they got drunk and tried to abduct the women, including Hippodamia who was carried off by the intoxicated centaur
Eurytion or
Eurytus. The Lapiths won the ensuing battle, the
Centauromachy, a favorite motif of Greek art.[5][6][7]
Punishment in the Underworld
Hippodamia died shortly after Polypoetes' birth, after which Pirithous went to visit Theseus at Athens only to discover that Theseus' own wife,
Phaedra, who, according to
Ovid, felt left out by her husband's love for Pirithous,[8][9] was dead.[10] Thus, Pirithous and Theseus pledged to marry daughters of
Zeus; Theseus chose
Helen of Sparta and together they kidnapped her when she was 13 years of age and decided to hold on to her until she was old enough to marry. Pirithous chose a more dangerous prize:
Persephone herself. Theseus objected, and tried to talk him out of it, as this act would be too blasphemous; but Pirithous insisted, and Theseus was bound by his oaths, so he agreed.[11] They left Helen with Theseus' mother,
Aethra, at
Aphidnae, and traveled to the
underworld. When they stopped to rest, they found themselves unable to stand up from the rock as they saw the
Furies appear before them.
Rescue
Heracles freed Theseus from the stone, but the earth shook when he attempted to free Pirithous.[12] He had committed too great a crime for wanting the wife of one of the great gods as his own bride.[13] According to a
scholium on
Aristophanes, in a lost play by
Euripides, Hades had Pirithous fed to
Cerberus for his impiety.[14] By the time Theseus returned to Athens, the
Dioscuri (Helen's twin brothers
Castor and Pollux) had taken Helen back to
Sparta; they had taken captive Aethra as well as Pirithous' sister, Physadeia, and they became handmaidens of Helen and later followed her to Troy.[15]
The rescue of Theseus and Pirithous acquired a humorous tone in the realm of Attic comedy, in which Heracles attempted to free them from the rock to which they had been bound together in the
Underworld (for having tried to carry off
Persephone). He succeeded in freeing only Theseus and left behind his buttocks attached to the rocks. Due to this Theseus came to be called hypolispos, meaning "with hinder parts rubbed smooth."[16][17] This may have been a later invention.
Pirithous was worshiped at Athens, along with Theseus, as a hero.[18][19][20][21]
