"Whilst these are belching it forth their sooty jaws, the City of London resembles the face rather of Mount Ætna, the Court of Vulcan, , or the Suburbs of Hell, than an Assembly of Rational Creatures... For when in all other places the Aer is most Serene and Pure, it is here Ecclipsed with such a Cloud of Sulphure, as the Sun itself... is hardly able to penetrate... and the weary Traveller, at many Miles distance, sooner smells, than sees the City to which he repairs."
