Late Renaissance Italy abounds in alchemy and Aristotle, yet it trembles on the brink of the modern world. Galileo’s new telescope encapsulates all the contradictions of this emerging reality. Then one night a stranger presents a different type of telescope for Galileo to peer through, enabling him to see the world of humans three thousand years hence.

Galileo will soon find himself straddling two worlds, the medieval and the modern. By day his life unfurls in early seventeenth century Italy; by night he is transported through dimensions of time and space no other man of his time could possibly comprehend. Inexorably, Galileo faces trial for religious crimes in his own time, while in the new world he discovers, where science assures men that they can perform wonders, but does not tell them what wonders to perform, he is revered.
