Doctors Commons. 19th-century artwork of the interior of Doctors Commons, Knightrider Street, City of London, UK. Demolished in 1867, this building housed a society for those practising civil law. This artwork is from 'The Microcosm of London', a series of 104 hand-coloured aquatints depicting London buildings and scenes. They were published by Rudolph Ackermann between 1808 and 1810, and then collected in three folio volumes. The artworks combined architectural details by Charles Augustus Pugin, and human figures drawn by Thomas Rowlandson. This aquatint, published 1 August 1808, was engraved by Joseph Constantine Stadler.
