Hyginus Fabulae, 130: Icarius and Erigone.

     When Father Liber had come among men to manifest the sweetness and pleasantness of his fruits, he enjoyed welcome hospitality in the home of Icarius and Erigone. He gave to them a full skin of wine as a gift and commanded them to disseminate it to all other lands. Icarius loaded his wagon and came with Erigone his daughter and Maera their dog to the shepherds of Attica; there he showed the type of sweetness the wine possessed. When the shepherds drank beyond moderation, they became drunk and collapsed. Those who adjudicated the problem determined that Icarius had administered a toxic potion to them and murdered him with cudgels. However, the dog Maera howled over the murdered Icarius and showed Erigone where her father lay unburied. When she arrived there, she hanged herself in the tree above her father's corpse. In response to this deed, Father Liber became wrathful at the daughters of the Athenians and cursed them with similar punishment. And the Athenians sought from Apollo an oracle regading the matter. The response they received was that they were afflicted because they had neglected the death of Icarius and Erigone. In turn they exacted a punishment upon the shepherds and established for Erigone the festival of the Swing (i.e. ἡ Αἰώρα) because of the pestilence. Furthermore [they decreed] that for the vintner harvest they pour the first libation to Icarius and Erione. These two mortals were catasterized by the gods' will: Erigone as the constellation Virgo, whom we also know as Justice (Libra); and Icarius is known in the stars as Arcturus; the dog Maera as Canicula (Sirius, or the Dog Star).

     130 Icarius et Erigone

Cum Liber pater ad homines esset profectus ut suorum fructuum suauitatem atque iucunditatem ostenderet, ad Icarium et Erigonam in hospitium liberale deuenit. iis utrem plenum uini muneri dedit, iussitque ut in reliquas terras propagarent. (2) Icarius plaustro onerato cum Erigone filia et cane Maera in terram Atticam ad pastores deuenit et genus suauitatis ostendit. pastores cum immoderatius biberent ebrii facti conciderunt; qui arbitrantes Icarium sibi malum medicamentum dedisse fustibus eum interfecerunt. (3)Icarium autem occisum canis ululans Maera Erigonae monstrauit ubi pater insepultus iaceret; quo cum uenisset, super corpus parentis in arbore suspendio se necauit. ob quod factum Liber pater iratus Atheniensium filias simili poena afflixit. (4)de ea re ab Apolline responsum petierunt, quibus responsum est, quod Icarii et Erigones mortem neglexissent. quo responso de pastoribus supplicium sumpserunt et Erigonae diem festum oscillationis pestilentiae causa instituerunt, et ut per uindemiam de frugibus Icario et Erigonae primum delibarent. (5) qui deorum uoluntate in astrorum numerum sunt relati; Erigone signum Virginis, quam nos Iustitiam appellamus, Icarius Arcturus in sideribus est dictus, canis autem Maera Canicula.
