"Part of what I saw in the project was an objectification of the body," he said. "We generally consider that to be a female thing. It would make a stronger statement if we had some male breasts in there as well."
Echelman said another important aspect of the project was that women were casting their own breasts, as opposed to men usually depicting breasts in art.
She said that the breast means different things to different people.
"There are multiple associations with the breast," she added.
Allison L. Unruh '97, one of Echelman's research assistants, said that some of the historical meanings of the breast in art have been nurturing, charity and sexuality.
Echelman said Louise Bourgeois and Eva Hesse, two American sculptors, were artistic inspirations for the breast project.
Echelman's project was funded by the Office for the Arts, Adams House and the Radcliffe College Research Partnership
