Methinks already from this chemic flame,
I see a city of more precious mould:
Rich as the town which gives the Indies name,
With silver paved, and all divine with gold.
Already labouring with a mighty fate,
She shakes the rubbish from her mounting brow,
And seems to have renew'd her charter's date,
Which Heaven will to the death of time allow.
More great than human now, and more august,
Now deified she from her fires does rise:
Her widening streets on new foundations trust,
And opening into larger parts she flies.
Before, she like some shepherdess did show,
Who sat to bathe her by a river's side;
Not answering to her fame, but rude and low,
Nor taught the beauteous arts of modern pride.
Now, like a maiden queen, she will behold,
From her high turrets, hourly suitors come;
The East with incense, and the West with gold,
Will stand, like suppliants, to receive her doom!
