"But at my back I always hear
Time's winged chariot hurrying near;"
-Andrew Marvell, To his Coy Mistress
Now, as everyone knows, that's a line Eliot riffs on in The Waste Land. What I didn't know, and only realized a few days ago, re-reading Virgil (while thinking about the whole stud / stallion / wild horses as a metaphor for sexual desire - but that's a whole other story), that those lines themselves probably come from this :
"You've seen - surely you've seen - how in a race, right from the off,
the chariots will gobble ground to take the lead,
and the charioteers, their hopes sky high and hearts in mouth,
lean forward as they ply their whips
and strain to give the horses their head, pushing them on.
The wheels are turning so quickly they burn.
Now up, now down, as if they're poised for take-off.
And no let up, and no let off, they're kicking up such a storm.
On their backs they feel the clammy breath of their pursuers."
- Virgil, Georgics III. 103-111 (translation by Peter Fallon)
The more things change, etc.
 I say probably because this is pure conjecture on my part. On the one hand, I feel fairly certain that Marvell would have been familiar with the Virgil, which makes the connection likely. On the other hand, it's possible that Fallon, in translating Virgil, is (consciously or unconsciously) channeling Marvell (for an alternate translation, see here). Or the whole thing could be just coincidence. I suppose there are people out there who study / research this sort of thing and would know for sure. But frankly, I'm uninterested in whether I'm right or not. The speculation's the point.
