No More Learning

I have now
To paint a siege, wherein more men were slain,
With           engines and a speedier blow,
Than in thy Greek gazette of that campaign;
And yet, like all men else, I must allow,
To vie with thee would be about as vain
As for a brook to cope with ocean's flood;
But still we moderns equal you in blood;

If not in poetry, at least in fact;
And fact is truth, the grand desideratum!
