Philosophers and poets in times past tried to figure out why the stainless moon smoothly polished, like a diamond in Dante's words, had stains. The agreed solution was that, like a mirror, it reflected the imperfect Earth. Today we smile, but it was a clever way to understand the Moon in a manner that was consistent with the beliefs of their age. The Moon is no longer the in thing. We see it as often as the Sun and give it little thought ED we've become indifferent. However, the Moon does reflect more than just sunlight. The Moon, or more precisely the nomenclature of lunar craters, still holds up a mirror to an important aspect of human history. Of the 1586 craters that have been named honoring philosophers and scientists, only 28 honor a woman. These 28 women of the Moon present us with an opportunity to meditate on this gap, but perhaps more significantly, they offer us an opportunity to talk about their lives, mostly unknown today.
