This year’s exhibition, which opened on 14 June 2019, is dedicated to the numerous illustrations commissioned by Cassiano dal Pozzo at the beginning of the sixteenth century in Rome. In an attempt to produce a visual encyclopaedia of knowledge, it formed a so-called ‘Paper Museum’, covering around 10,000 drawings, watercolours and prints of antiquities, architecture, zoology, botany and geology, social customs and ceremonies, costumes, portraits, topography and military maps. The Paper Museum is now part of the Royal Collection after it was acquired by George III in 1762.
