This novel is set during the cataclysmic transformation that accompanied the death of the Roman Empire at the beginning of the middle ages when the Christian Church stamped out the vestiges of Roam cultural and religious heritage.It was Theodosius in the late 4th century that mandated trinitarianism and struck down all pagan forms of worship. He hastened the fall of Rome by splitting the empire into two sections, leaving his inheritance to two sons, both incompetent: Honorius ruled in the West; Arcadius in Constantinople. The hostility between the two malcontents forms the backdrop for the novel which begins and ends in the year 414 A.D. although flashbacks take it back further.Ambrose, Bishop of Milan, is a prominent character. By thwarting Theodosius's demands for restitution to Jews for their destroyed property -- Theodosius protected Jews -- Ambrose began the struggle between the state and religious authority for supreme power. Ambrose and Hadrian, an ex-Roman civil administrator both view the world through restricted vision which was to become the predominant view for many centuries thereafter. These views are reflected by the drama surrounding a Roman who is arrested for ostensibly conducting archaic and illegal religious celebrations.
