Excerpt from Alvan Clark and Sons Artists in Optics Clarks made the objectives for the largest refracting telescopes in the world; and the fifth of their efforts, their 40-inch lens at the Yerkes Observatory, has never been surpassed. Their optical work, which was recognized as unexcelled anywhere in the world, was the first significant American contribution to astronomical instrument making. American telescopes had been made before, but none compared to those of Euro pean manufacture; by the end of the 19th century, however, partly because of the example set by Alvan Clark Sons, several other Ameri cans were making fine astronomical instruments.

"Celestial Images" celebrates the Golden Age of astronomical charts. Illustrations of cosmologies and heavenly phenomena entered an innovative phase at the time of the Renaissance, when the invention of printing improved the means of disseminating scientific knowledge and advances in astronomy revealed new information to be portrayed. This fortuitous conjunction engendered printed astronomical charts of surprising accuracy and delicate beauty. Assembled here from the Mendillo Collection of Antiquarian Astronomical Charts and Maps are over eighty examples of some of the finest celestial cartography created. There are star charts (maps of the constellations and the full celestial sphere), charts of planetary systems (cosmologies), and a smaller third category, charts of celestial phenomena (such as nebulae, comets, and eclipses). Together, they pay homage to the time when simple systems explained the universe and humankind held friendly commerce with the skies.
