T H E A R T O F P U R E C O L O U R 1 JOHN WELLBORN ROOT AND THE ROLE OF POLYCHROMY IN ARCHITECTURE by Valentino Danilo Matteis It’s 1891: twenty years have passed since the ashes of the Great Fire have cooled, and one of the most astonishing buildings in Chicago has just been completed. It is an enormous pile of purple/brown bricks produced by the Indiana–based Anderson Pressed Brick Company, and perfectly aligned by masons from George Fuller and Co. 2 . A building whose top recalls the termination of an ancient
Egyptian papyrus column, reaching the vertiginous height (for the times) of sixteen stories. With no ornamentation, apart from its unusual colour, carefully detailed bay-windows, and a gently curving cornice and basement, the Monadnock is without a doubt one of the strangest and most interesting buildings in the architectural history of Chicago. Designed by John W. Root and Daniel H. Burnham
