sorry.

for some purposes, and in some academic jargons, though i wasn't using one, 'races' was the wrong word. i should have said 'peoples'.
subjective thinking isn't always useless. on reading in a 19th century novel that a certain character is 'italianate' in appearance, most of us would immediately envisage a dark haired, short, olive-complexioned, brown-eyed person before recalling that there are also fair ones up in the north where there used to be gauls. or if shown a photograph of a tall, fair, blond woman and a short, olive-complexioned, dark-haired one, most of us, if asked to identify the italian would point to the short dark-haired one, expecting to find 'italian' features there, and would be surprised to find the 'italian' features on the tall, fair, blond woman. i think that subjectively, most of us would be happy with the idea that mediterranean people in general are darker than most northerners, shorter too, and less prone to baldness in old age.
it would be against all reason to dismiss this perception just because we haven't got statistics. it would also be bringing arguably unjustifiable contempt for common sense, nous, direct personal experience, common knowledge, and the myriad other perfectly dependable non-academic ways of knowing that all manner of human beings have evolved over the past several millennia. that's why many universities are now re-examining the whole phenomenon of 'official' knowledge and its associated power structures from post-modern perspectives developed during the last century and advancing rapidly in this one. the official historians no longer claim to know facts like that, though text books still have to teach the prevailing theories long after they've been discarded by the inner circles.
But as the class of people who had statues made of themselves would generally be the same class of people who were writing things down,
well, that's gone beyond the evidence right into the realms of *prolly-would productions*, which is where we've been with it over the past centuries.
the sense we've got of our past is constantly changing as paradigms shift under the weight of new evidence, new insights, and new tools and lenses for interpreting the vast array of data as it comes to us form many resources, and managing the fine-tuning of our historic vision. a thorough discussion of this is probably beyond the scope of this thread, and anyway, off-topic. if you want to take it off the board, congenially of course, pm me.
my take on it is this: if you wished to govern a remote foreign people, you'd send them a statue, have your praises mightily sung around it, and you'd send them
a constant stream of literature in your entourage's best efforts at their language, translated perhaps by one of your scholars so that the foreigners could read it, with a law book, a biography and a full account of what glorious things you'd done to warrant their meek submission or grateful worship, along with an up to date account of the history of your culture. according to this hypothesis, any site found with a lot of texts in the local language or an inflected form of it, is not likely to be the home of the culture of origin of the statue, and very unlikely to be the native language of the statue. i'm speaking on the same 'prolly' level as you are, but that's what hypothesis is, isn't it?
There is no way on this green earth I would do that to my head

well said, nicholaas. it resounded like the thud of a druid's staff on the hard ground.
