How Fast History Becomes Myth

Our current best answer is that legend can attach to a real person quickly — likely within a few generations — and that a well-documented figure gives us the clearest way to measure that speed. When we know exactly when someone lived and died, we can watch how fast borrowed legend piles onto the real record. Our anchor case is Alexander the Great, whose life is fixed by coins, firsthand accounts, and a firm death date of 323 BCE. Stories about him later absorbed much older legendary material, including the immortality quest first told about Gilgamesh. That gives us a working clock for how a real person turns into a myth. But we should be honest about a gap in that clock. The clearest support for the borrowing itself comes from Jastrow, who states plainly that Gilgamesh's exploits were transferred to Alexander — "Gilgamesh lives again in Alexander." What Jastrow does not give is a date for when that transfer happened. So our evidence firmly supports that the borrowing occurred, but not yet the specific "one to three centuries" speed the claim leans on. The number is still an estimate, not a measured result. On telling truth from later invention, we hold to one careful limit: internal clues can date a tradition but cannot verify it. A place-name that commemorates an event sets a floor on how old the telling is, because a name cannot predate what it names — yet that dates the story, not the fact behind it. The biggest question right now is whether we can actually date when the Gilgamesh material attached to Alexander, since without that date our claimed speed for myth formation remains an untested estimate.
