here, I started with Dardanus, the mythical founder, as I thought, of Troy. Reading further here, I find that Dardanus is said to have founded Dardania and his great-grandson, Ilus, to have founded Ilion, which is Troy. (Because Ilion is Troy, Homer's first epic, set during the siege of Troy, is called the Iliad.) However, the words "Trojans" and "Troad" had already originated from the name of Dardanus' grandson, Tros. In any case, Dardanus is a grand progenitor, especially since he is a son of Zeus.
My list of "Historical Achievements" is, of course, mostly mythical, legendary and fictitious although it crosses over with history in the person of Augustus.
I mention all this because Dominic Flandry also makes a connection with Troy:
"He had not been truthful in claiming indifference whether he lived or died: not while a supple young woman stood clad in sunlight, and blooded horses stamped on the ringing plains of Ilion, and smoke curled fragrant about coffee and cognac on Earth. But half the pleasure came from these things being staked against darkness."
-Poul Anderson, Captain Flandry: Defender Of The Terran Empire (New York, 2010), p. 318.
Maybe heroes of this kind of fiction are obliged to think like this? But here I differ from Flandry. I derive no pleasure from our civilization being staked against darkness. If civilization could be made secure, then there would still be many intellectual and other challenges to stretch our abilities. Risking death is not my idea of a good time although, of course, we enjoy reading about Bond and Flandry doing precisely that.
