Gnostics have always sought to "know" rather than to accept dogma and doctrine, often to their peril. This inquiry into Gnosticism examines the character, history, and beliefs of a brave and vigorous spiritual quest that originated in the ancient Near East and continues into the present day.

Lawrence Durrell writes, "This is a strange and original essay, more a work of literature than of scholarship, though its documentation is impeccable. It is as convincing a reconstruction of the way the Gnostics lived and thought as D.H. Lawrence's intuitive recreation of the vanished Etruscans."
