The epinetron (plural - epinetra) was an Attic female pottery vessel. It was used by Attic women whilst weaving to prevent grease from the wool from spoiling their clothes. More ornamental epinetrons were placed on the graves of unmarried girls, or dedicated at temples, usually to the goddess Athena.
Often, it was a wedding gift and had a head or bust of Aphrodite on the front of it. It was decorated with scenes of women weaving or even amazons.
