My husband and I found the WorldWide Telescope a few months ago, and we’ve been staring into the heavens ever since. “Which planet would you like to see first?” he asked me once he'd loaded the program onto his computer. No question: Saturn. I’ve always been fascinated by those rings. A few clicks of the mouse and there they were, circling and circling, a sash of light, a halo, a crown. We looked at Jupiter next, with its great red spot. We looked at Mercury, Venus, Mars and Pluto. Each planet was unique, different from every other. But what they had in common was this: they shone out of utter darkness.

Dozens, perhaps hundreds, of late medieval and Renaissance paintings and sculptures depict the Virgin Mary with one breast exposed as she is nursing the infant Christ. The origins of the image are disputed, but whatever its origins, depictions of the lactating Virgin acquired new meaning and new urgency in mid-14th-century Tuscany. In communities under siege from plague, wars and malnutrition, the Virgin’s breast was a symbol of God’s loving provision of life, the nourishment and care that sustain life, and the salvation that promises eternal life.
