Athenians of the Classical age were aware that the festival was of great antiquity. Its ritual marriage of a queen to Dionysus recalls myths concerning Theseus and Ariadne, but this is no longer considered a dependable sign that the festival had been celebrated in the Minoan period. Since the festival was celebrated by Athens and all the Ionian cities, however, it is assumed that it must have preceded the Ionian migration of the late eleventh or early tenth century BC. This still makes it the oldest datable part of the Eleusinian Mysteries.
The month Anthesterion is named after the festival and not vice versa.[1] /wiki/Anthesterion
Thucydides noted that "the more ancient Dionysia were celebrated on the twelfth day of the month of Anthesterion in the temple of Dionysus Limnaios ("Dionysus in the Marshes").[2] /wiki/Thucydides

Harrison argued that the name should be understood as a reference to grave holes, not pots. Rohde[13] and Nilsson[14][15] took it to mean water pots, connecting it with the Hydrophoria honoring the spirits of the dead thought to have perished in the Great Flood of Deucalion. /wiki/Jane_Ellen_Harrison
