I went to Project Gutenberg to look something up, and this was one of the recent releases (March 26, 2023) featured on the homepage.
It's not yellow, but pterodactyls of any color grace the covers of few enough books to make it a noteworthy coincidence nonetheless.
I scrolled down to the table of contents and saw that the third chapter, about pterosaurs, is called "Pirates of the Air" -- pretty similar to "winged raiders," isn't it?
According to the rather dated science of The Monster-hunters (1916), all mass-extinction events were caused by ice ages, and the periods punctuated by these ice ages are characterized as "empires."
With this upheaving, came the First Age of Cold. The coal-forests died, the pine-trees took their places. The marshes became plains. Nearly all species of life belonging to that warm age died. The Empire of the Fishes and Amphibians ended. The Mediterranean slowly diminished in size and again became an inland sea, while in Europe to the north, Africa to the south and in America, beyond the Atlantic, the Empire of the Reptiles began. . . . Yet the slow death of cold which had awaited the Fishes and Amphibians in the Permian Revolution was awaiting the Reptiles also. The Second Age of Cold was near. After the Cretaceous Period, the land began to rise, until, when hundreds of thousands of years had elapsed, the northern part of Europe was elevated, the Mediterranean lost its opening to the ocean, and became once more an inland sea. Then came the Second Ice Age, the second cataclysm of want and death. The Pterodactyls died away completely, the huge reptile monsters fell by thousands and all the giant Saurians had to give place to the warmer-blooded mammals.
The above quote is not in the "Pirates of the Air" chapter but in the next one, "Seeing the Sea-serpent," so the fact that pterodactyls get top billing in the list of casualties of the K-T extinction event is curious. This syncs with my March 18 post "Sync: Another yellow ptero, St. Valentine's Day, Empire of the Ants."
There, too, pteros are unexpectedly highlighted (in the thumbnail) in an account of the K-T extinction. And, as the title indicates, the same post features a sync having to do with the phrase "Empire of the Ants" -- paralleling the similar "Empire" phrases in The Monster-hunters.
The "Seeing the Sea-serpent" chapter also features this illustration, captioned "The Fiercest Monster That Ever Lived."
Isn't that a familiar turn of phrase? Where have we seen that before? Oh, right.
Looking at the list of illustrations after the table of contents, I noticed that the second one on the list was called "Scylla of the Seven Heads" -- one of a small collection of images of "Monsters Thought Real by the Ancients."
This got my attention because on March 17 I had posted old (2015-16) Scylla and Charybdis syncs in "Sync: Skylark and Charybdis" and included a picture of Scylla, though with the canonical six heads rather than seven.
I Ctrl-F'ed Scylla to see if she put in any other appearances in The Monster-hunters, and lo and behold:
"No signs of Scylla and Charybdis," said a voice behind him.
"That's so, Uncle George," the boy said, turning, "this is where the old Greeks believed Scylla to be, isn't it? But I'd rather tackle that six-headed monster, in spite of all her appetite, even though each head took a man from the crew, as it did from Ulysses' ship, than I would run the gauntlet of the guns of Gibraltar let loose on us. Still, even Scylla might be uncomfortable. What do you suppose was the basis of that old story, Uncle George!”
"Personification of the peril of adventure,” was the reply. “That is why Scylla and Charybdis were first said to hold guard over the Straits of Messina, between Sicily and Italy, while afterwards the twin terrors of the ravening whirlpool and the six-headed man-eating woman monster were located at Gibraltar. As the Straits of Messina became more familiar, the terror had to be put farther away, where only the most daring would venture.
"Remember, Perry, that the Greeks believed they saw a god or a goddess or a demon in all the forces of Nature. The sea was under the rule of Poseidon, or Neptune, as the Romans called him; the dawn goddess Eos, or Aurora, was the mother of the Winds, such as Boreas, the North Wind and Zephyr, the West Wind. So, you see, the Greeks felt sure that every point of danger must be guarded by some kind of demon or monstrous form, while beautiful places were inhabited by fair maidens. After all, Perry, it's not so very long ago since people believed in mermaids. So far as that goes, some people believe in them still."
Right after the references to Scylla and Charybdis, characterized as "the twin terrors," we read of "the dawn goddess Eos, or Aurora." In my March 7 post "Fever dreams and sync: Popol Vuh twins, Spinal Pap, stone worship, and more," I discuss terrible twins in Mayan myth and The Matrix Reloaded, and I also mention this:
In my flytrap post, the key phrase was "blushing trap," which I interpreted as a description of the rosy lobes of the Venus flytrap. The expression made me think of the Homeric "young Eos with fingertips of rose." In her comment, Debbie quotes Ovid on the Roman equivalent of Eos: "Aurora, watchful in the reddening dawn, threw wide her crimson doors and rose-filled halls." These rose references link back to William John's carnivorous "Poison Rose of Poetry."
