Arrhephoria was a feast among the Athenians, instituted in honor of Athena. The word is derived from the Greek term Ἀρρηφόρια, which is composed of ἀρρητον, "mystery", and φέρω, "I carry". This feast was also called Hersiphoria, from Herse, the daughter of Cecrops, on whose account it was established. Historical celebration On the Athenian Acropolis two girls aged between seven and eleven were elected to live for a year at a time as arrhephoroi, tending the sacred olive tree and weaving, with the help of other women, the new robe for Athena. Proud parents commemorated their daughters' service by making dedications on the Acropolis. At the annual festival of the Arrhephoria the girls (according to Pausanias) placed on their heads what the priestess of Athena gives them to carry. Neither the priestess nor the girls know what it is she is giving them. In the city there is a sacred precinct not far from that of Aphrodite in the Garden and through it runs a natural underground passage. Here the virgins descend. Down below they leave behind what they have brought and take something else and carry it, veiled as it is. These two virgins are discharged forthwith and others are taken up to the Acropolis in their place. Interpretation of the festival is difficult because of the lack of sources, but it is clear that the virginal arrhephoroi are chosen from the noblest families of the city and are deployed in a context of impregnation (dew), sexual power (Aphrodite and Eros), and birth (Erichthonios). The word "arrhephoros" etymologically probably means "dew carrier", which at first sight does not help. The arrhephoroi were charged with weaving the peplos (garments) for Athena. The aletrides ground the grain for Athena. The arkios were the priestesses who celebrated a rite intended to forgive an offense against Artemis. The kanephorai were the girls who carried the baskets with all of the offerings to the festival. Kanephoros were common place in rituals or feasts similar to Arrhephoria as it was a held position of honor in Ancient Athens. Archaeological evidence reveals that from near the Erechtheion a secret stairway led off the Acropolis past a small rock-cut shrine of Eros and Aphrodite, near which was the precinct to which they were going. The mythical associations of the arrhephoroi are with their starting-point the Erechtheion. In the fifth century B.C. Aristophanes wrote Lysistrata which explained the
