This series includes visual materials used in writings by Jay and Mary Hambidge about dynamic symmetry. The bulk of the materials appears in publications authored by Jay Hambidge or was part of his research to develop the idea of dynamic symmetry. VIS 1.25 through VIS 1.39, arranged alphabetically by publication title, contain plates, sketches, and diagrams included in a small monthly magazine published for Jay Hambidge by Yale University Press, The Diagonal, and in numerous books, among them Dynamic Symmetry in Composition, The Elements of Dynamic Symmetry, The Parthenon and Other Greek Temples, and Practical Applications of Dynamic Symmetry. The remaining folders in Series II are arranged alphabetically by subject title and include images used in various publications. By and large, these photographic prints are of Greek and Roman antiquities and are accompanied by or include Jay Hambidge's hand-written computations and marginalia.
