Background

Zallinger was an art student who in the early 1940s had been painting seaweed drawings for the Peabody museum. Dr. Albert E. Parr, then director of the Peabody Museum, had been unhappy with the appearance of the Great Hall of the museum, which he felt was devoid of color and barren.Scully, 18. Parr asked Lewis York, Zallinger's professor at art school, if he knew anyone who would be able to fill a large wall space in the Hall; York recommended Zallinger. On March 1, 1942, Zallinger was officially appointed to the wall-painting project. Initially, Zallinger planned on dividing the wall space, measuring 110 feet in length, 55 feet in width, and 26 feet in height, into separate panels.Scully, 19. After discussions with his supervisors, Zallinger instead decided on a different concept, which would use the entire wall for a "panorama of time." Because Zallinger had never painted dinosaurs, Dr. G. Edward Lewis, the museum's curator of vertebrate paleontology, and Dr. George Wieland proceeded to give Zallinger a six-month crash course in

Painting

Zallinger sketched out his plan for the mural on a sheet of rag paper, which could be unrolled to edit individual sections. The position of entrances to the hall and the sequence of which Peabody's fossils are arranged made the mural be "read" from right to left, instead of the customary direction.Scully, 20.

Impact

''The Age of Reptiles'' won Zallinger several awards. Zallinger was awarded with a Pulitzer Fellowship in Art in 1949, and the painting was featured as a postage stamp in 1970. Despite its somewhat outdated view of dinosaurs, ''The Age of Reptiles'' is still notable for its historical and artistic merit and as the largest natural history painting in the world. It has been an inspiration to many visitors including both
