In early-seventeenth-century Venice, a mysterious stranger tells Galileo about magnifying lenses he has seen in the Netherlands, inspiring the scientist to construct a workable spyglass and later view the bodies in the night sky with it. One night, in company with the visitor, Galileo is transported centuries into the future and spatially to the moons of Jupiter. He’s the center of a dispute there between those who believe that, if he does certain things, their future will never come to pass and those who don’t believe it. Thereafter, Galileo strives to understand the wonders of what, during apparent syncopes, he is seeing on the Jovian moons, while earning his living and making his own discoveries in Italy. The latter eventually lead to arraignment for heresy for supporting the Copernican theory. Robinson skillfully melds the disputes of seventeenth-century Italy and speculation on future philosophical conflict, meanwhile providing an engrossing portrait of the epochal scientist—so engrossing that one may feel tempted to learn Tuscan to see how true-to-life Robinson’s depiction is. --Frieda Murray
