He went looking for it because of the Iliad and the existence of Mt Mazama was 'historical fact' to the people living nearby almost 8,000 years ago.
The regular intervention of the gods was historical fact to the Greeks 2,500 years ago, but that doesn't mean we should take it either as an indicator that the gods were real or that something like the gods (sorry, aliens????????) were real. Sometimes a story is just a story.
@Dachs, surely Homer is referring to a specific Troy? Or if Homer never existed (what's the consensus on that these days?), one particular Troy had to be the first to enter the myth. So claiming the "Homeric Troy" never existed because the Iliad isn't historical is just semantic twisting.
It's also reasonable to say that the scholarly consensus on Troy was at least partially corrected by a man chasing the myth, no?
The scholarly consensus on Troy in the eighteenth century was that it was a myth. After Schliemann's efforts to popularize his finds, many academics bought his Trojan fables hook, line, and sinker, and it took decades for even historians to get serious about pre-geometric Aegean archaeology again. Popular literature still hasn't caught up. I would say that chasing the myth undoubtedly set the field back and contributed to the current state of things, where people go around believing that Achilles and Hektor really were dudes who did things.
There is no consensus on the "real" Homer (zero, one, or multiple humans?). There is no possible way to know where the
Iliad and
Odyssey "came from" and to what they are referring. We lack the relevant sources. Insofar as there is scholarly consensus, it's that the Homeric epics' original composition - not "when the oral tradition was written down" (the Greeks at that time
still didn't employ written language), but their
actual date of composition - postdates the events that supposedly took place in them by four hundred years. This is one of the many, many reasons to believe that they don't have much (if any) historical value.
Even in archaeological investigations of sites within the sweep of recorded history, there's been a strong push to decouple archaeology from written sources and let the archaeological investigations speak for themselves. Written sources can be very wrong about things and cause people to make serious errors by only viewing the archaeology through the prism of written events. Even when the written sources aren't wrong,
the way modern people interpret them can be wrong and lead archaeological inquiry into a dead end. A fair number of very good archaeologists have pointed out that their field is not just a matching game, where you desperately try to link each excavated artifact to something attested in a written source, no matter how tenuous the connection.
So using
an actual myth - which
everybody agrees is at
least 95% wrong - to inform archaeological inquiry is so much worse. It irrevocably shifts the cognitive terms of the excavations. Instead of viewing the ruins on their own terms, people look for comparisons with Bronze Age Greece; even if the comparisons aren't very good, they take over the terms of the investigation such that convincing people that other explanations are better is
so much harder. There are
still academics these days taken in by the notion of Hisarlık = Homeric Troy, or at least willing to entertain the notion in order to sell books. Once we strip away all of the things about the
Iliad that we can conclusively prove were impossible and had nothing to do with the Hisarlık site, we are left with very little indeed, none of which has any explanatory power.
^That seems likely, given the other cities in the Iliad are real anyway. Although for some of the smaller ones it isn't known if they were where it is thought they were.
There are
loads of places in the
Iliad and
Odyssey that don't work for Mediterranean geography, and most of the places that people
did supposedly identify with real locations have been seriously questioned.
Fundamentally, trying to match the epic poems up to real locations is pointless. The
Iliad and
Odyssey were not historical texts. They were not contemporary works. They give very little insight into the way things worked for real people in the Bronze Age Aegean. They are hopelessly anachronistic.
