Marvelous metaphor by Shakespeare, suggesting (to me) that the foment and energy of a city like London forges thought among its people. Something taut and elemental here, with the din and heat of a blacksmiths workshop echoing the noise and bustle of a great city.
But now behold,
In the quick forge and working-house of thought,
How London doth pour out her citizens!
