O'Leary is a most keen observer of the darklight reflected in words, especially in those of the sacred tradition. Drawing poetic energy from the black deposits of the Text, O'Leary advances the gnostic effort of (re)constructing a hidden God. I know this book will be placed between the works of Baudelaire and Scholem in the universal library.

—Andrew Joron, author of Fathom

Depth Theology harks back to some of the oldest moments of record and revelation while keeping baseball, parking lots, bumper stickers, boredom, broken drivebelts, Tommy Hearns, and the like in view. To call it old school is barely a beginning. Learned, bold, and assertive, it is a marvel of thinking the world's inwardness.

—Nathaniel Mackey, author of Atet A.D.

While asserting his desire to produce a revelatory poetry, O'Leary moves, with a boldness that lays bare the inconclusive quality of the revealed. The religious imagination that evolves in these poems is unfettered by dogma and richly colored by erudition while granting—repeatedly, courageously, and even humorously—the limits of human language and experience to invoke the inwardness O'Leary would map.

The poet of my general age group that I'm most consistently startled by.

—Third Factory

This volume . . . is a massive contribution to contemporary poetry.

—Cultural Society

To my notion, the best poems in Depth Theology derive their intensity from border skirmishes between body and spirit, waking and dreaming, concealment and revelation—precisely because in them we encounter the greatest reciprocity of movement.
