"Keithley’s talent is remarkable; he seems to possess Whitman’s visionary imagination, that rare ability to evoke powerful, scaled-down, lyric details in the service of a vast structure."
—The American Poetry Review

“So moving and precise is Keithley’s depicition of the life-loving Galileo and his enemies’ death-dealing tools that the ending becomes inevitable if no less tragic.”
—Booklist

“[Keithley] displays his powers of spare yet arresting narrative in his new long sequence about Galileo. . . . a captivating poem woven of poems.”
