Erigone

ALTHOUGH Oeneus was the first mortal to be given a vine plant by Dionysus, Icarius anticipated him in the making of wine. He offered a sample from his trial jarful to a party of shepherds in the Marathonian woods beneath Mount Pentelicus, who, failing to mix it with water, as Oenopion later advised, grew so drunk that they saw everything double, believed themselves bewitched, and killed Icarius. His hound Maera watched while they buried him under a pine-tree and, afterwards, led his daughter Erigone to the grave by catching at her robe, and then dug up the corpse. In despair, Erigone hanged herself from the pine, praying that the daughters of Athens should suffer the same fate as hers while Icarius remained unavenged. Only the gods heard her, and the shepherds fled overseas, but many Athenian maidens were found hanging from the pine one after another, until the Delphic Oracle explained that it was Erigone who demanded their lives. The guilty shepherds were sought out at once and hanged, and the present Vintage Festival instituted, during which libations are poured to Icarius and Erigone, while girls swing on ropes from the branches of the tree, their feet resting on small platforms; this is how swings were invented. Masks are also hung from the branches, which twist around with the wind.
b. The image of Maera the hound was set in the sky, and became the Lesser Dog-star; some, therefore, identify Icarius with Bootes, and Erigone with the constellation of the Virgin.

1. Maera was the name given to Priam’s wife Hecabe, or Hecuba, after her  transformation into a dog, and since Hecuba was really the three-headed Death-goddess Hecate, the libations poured to Erigone and Icarius were probably meant for her. The valley in which this ceremony took place is now called ‘Dionysus’. Erigone’s pine will have been the tree under which Attis the Phrygian was castrated and bled to death, and the explanation of the myth seems to be that when the Lesser Dog-star was in the ascendant, the shepherds of Marathon sacrificed one of their number as an annual victim to the goddess called Erigone.
2. Icarius means ‘from the Icarian Sea’, i.e. from the Cyclades, whence the Attis cult came to Attica. Later, the Dionysus cult was superimposed on it; and the story of the Athenian girls’ suicide may have been told to account for the masks of Dionysus, hung from a pine-tree in the middle of a vineyard, which turned with the wind and were supposed to fructify the vines wherever they looked. Dionysus was usually portrayed as a long-haired, effeminate youth, and his masks would have suggested hanged women. But it is likely that dolls representing  the fertility goddess Ariadne or Helen were previously hung from fruit-trees. The girls’ swinging at the vintage festival will have been magical in its original intention: they represented bird-goddesses, and their swings made a semi-circle in honour of the new moon. This custom may have been brought to Attica from Crete, since a terracotta group found at Hagia Triada shows a girl swinging between two pillars, on each of which a bird is perched.
3. The name Erigone is explained by the mythographer as ‘child of strife’, because of the trouble she occasioned; but its obvious meaning is ‘plentiful offspring’, a reference to the plentiful crop induced by the dolls.
