Because all infants were breastfed in antiquity, the breast was viewed primarily as an emblem of nurturing and of motherhood. "Mastoi", breast-shaped drinking cups, and representations of breasts are among the votive offerings "(vota)" found at sanctuaries of deities such as Diana and Hercules, sometimes having been dedicated by wet nurses. The breast-shaped cup may have a religious significance; the drinking of breast milk by an adult who is elderly or about to die symbolized potential rebirth in the afterlife. In the Etruscan tradition, the goddess Juno "(Uni)" offers her breast to Hercules as a sign that he may enter the ranks of the immortals. The religious meaning may underlie the story of how Pero offered breast milk to her elderly father when he was imprisoned and sentenced to death by starvation (see Roman Charity). The scene is among the moral paintings in a Pompeiian bedroom that belonged to a child, along with the legend "in sadness is the meeting of modesty and piety". Pliny records medicinal uses of breast milk, and ranks it as one of the most useful remedies, especially for ailments of the eyes and ears. Wrapping one's head in a bra was said to cure a headache.
