Examines the presentation of Jesse as a visionary dreamer in depictions of the lineage of Christ. Discusses this iconography as a manifestation of medieval efforts to portray the relationship between the visible and the invisible. Traces the links between the form of the dreaming Jesse and 12th-c. genealogical diagrams and depictions of Jacob's ladder. ;
