Science writer Cutler (a contributing editor to The Forces of Change: A New View of Nature) re-creates a fascinating 17th-century world of political and religious upheaval and the progress achieved by curious scientists like the Danish anatomist and (according to Cutler) founder of geology, Nicolaus Steno (1638-1686). A one-time medical student renowned for "his preternatural skill with a scalpel," Steno discovered the parotid gland, which produces saliva, and tear glands. Steno's genius for anatomy provided him the tools to work on the mystery of fossils and the question of how seashells could be found in the rocks of mountains far from the sea. He hypothesized that layers upon layers of earth formed sediments in a sequence, recording a series of events and telling a story about the age of the earth. According to Steno, the stratum at the bottom is the oldest and that at the top is the youngest. Seashells, he said, found their way to mountaintops not by the great biblical flood, as many of his contemporaries believed, but by constant erosion and the sedimentation of soil. Steno published his discoveries in De Solido, after which he abandoned science, converted to Catholicism and spent the last 20 years of his life as an ascetic priest and eventually a bishop. In 1988, he was beatified. Cutler's animated and energetic prose provides a page-turning thriller of scientific discovery, and this splendid biography captures in intimate detail not only its subject but also the tenor of Steno's times.

From Booklist
In piquant contrast to the oft-told tale of Galileo, the acclaimed martyr of astronomy, Cutler recounts the little-known story of Nicolaus Steno, the neglected saint of geology. Living scant years after Galileo, Steno devoutly embraced the church even as he advanced a revolutionary science that tested orthodoxy at least as much as Copernicanism. Despite his conversion to Roman Catholicism, Steno was undeterred from his scientific quest to understand why petrified sharks' teeth--and other remains of sea creatures--frequently appeared in rocks high in the Tuscan mountains. With his publication of the principle of superposition, Steno gave scientists a key to reading the history of the planet in its rock layers, a premise still central to modern geology. His theory discredited many traditional readings of Genesis, but Cutler finds no evidence that church censors disapproved of Steno's work or that Steno himself ever regarded his theory as a threat to his faith. Indeed, Steno concluded his life in holy orders and ultimately qualified for posthumous beatification. A sophisticated portrait of a forgotten pioneer.
