Oddly, as soon as I saw it, it was familiar to me from a very early, distant memory, although I had no specific childhood recollection of it. Perhaps it was reproduced in one of my books on dinosaurs (an avid interest circa ages 5 through 10)? In doing a little armchair research I rediscovered another very familiar mural: the magnificent Age of Reptiles by Rudolph Zallinger. (Interestingly, like Astori, Zallinger was a Russian, from Siberia). Age of Reptiles is a massive 110 foot long fresco panorama completed in 1947 at the Yale Peabody Museum of Natural History. (I'm ashamed to say in my 4 years in New Haven I never did get over to the Peabody—I intend to go in August.) The mural was reproduced in several dinosaur books in the late 60s/ early 70s and that's how I know it.
Age of Reptiles (detail) Rudolph Zallinger
Zallinger was by far the better draftsman but there is something I love about Astori's Flying Reptiles. Somehow, his mural conveys "Lair of the Zorgons on planet Rilor" in a loopy science fiction sort of way, rather than "speculative view of life on prehistoric earth." Its a bit humorous (see the pterosaur antics in the details above) and I half expect to see a Maxfield Parrish nymph perched one of the rocks, nevertheless I'm simply drawn into that fabulous compositional spiral toward an ancient technicolor sunset.
