"In any case, it seems scarcely credible that Swimmer963 is unaware that poetry has traditionally tended to have (perhaps even by definition) a lot of metrical regularity and that many people strongly prefer it to be that way, so on your reading jimrandomh's comment seems to convey little actual information."
Apparently I was more unaware than I thought. Almost all the poetry I've read recently doesn't rhyme or fit into iambic pentameter, to the point that when I read poetry that does, it almost feels weird. (Granted, a lot of what I read is medieval and translated into English from Latin. Maybe it rhymed originally.)
My understanding of Latin poetry (pretty dang limited) is that it's based around meter dictating use of long and short syllables (rather than stressed and unstressed, as in English poetry), and that rhyme wasn't much used (it's too easy!). So it probably was in meter in the original Latin, but a different sort of meter.
Meter != iambic pentameter, though!
**Note: I'm not a poet. I hardly ever write poetry, and when I do, it's usually because I've stayed up all night. However, this seemed like a very appropriate poem for Less Wrong. Not sure if it's appropriate as a top-level post. Someone please tell me if not.**
Imagine
The first man
Who held a stick in rough hands
And drew lines on a cold stone wall
Imagine when the others looked
When they said, I see the antelope
I see it.
Later on their children's children
Would build temples, and sing songs
To their many-faced gods.
Stone idols, empty staring eyes
Offerings laid on a cold stone altar
And left to rot.
Yet later still there would be steamships
And trains, and numbers to measure the stars
Small suns ignited in the desert
One man's first step on an airless plain
Now we look backwards
At the ones who came before us
Who lived, and swiftly died.
The first man's flesh is in all of us now
And for his and his children's sake
We imagine a world with no more death
And we see ourselves reflected
In the silicon eyes
Of our final creation
