Giulio Camillo's Theatre of Memory: an architecture for the mind
Giulio Camillo Delminio designed a wooden theatre able to hold all knowledge: the story of the Theatre of Memory, its planets and the art of memory.
In 1532 the Dutch humanist Viglius Zuichemus wrote to Erasmus of Rotterdam that he had seen in Venice a strange wooden construction. It was a small amphitheatre, large enough to hold two people, full of images and drawers. Its inventor, Giulio Camillo, claimed that whoever entered it would be able to speak on any subject with the eloquence of Cicero. It was the Theatre of Memory, one of the strangest architectures ever conceived.
A famous and forgotten man
Giulio Camillo, known as Delminio, was born in Friuli around 1480 and died in Milan in 1544. He was a professor of logic and rhetoric, frequented the leading writers of his day and enjoyed a European reputation. King Francis I of France financed him so that he could complete his work, and Camillo spent some years in Paris. The wooden theatre has not survived, and we do not know whether it was ever completed in the form he dreamed of.
What remains of it is above all a small book, L'idea del theatro, published in Florence in 1550, a few years after his death. It is there that Camillo describes the structure with its images and meanings, though often in an allusive and fragmentary way. The text was dictated, according to tradition, in the last period of his life, and the modern reader finds in it more suggestions than precise instructions.
The art of memory
Camillo's project rests on a very ancient technique, the art of memory, described by Latin authors such as the Rhetorica ad Herennium and Quintilian. Orators imagined a building and mentally placed vivid images in precise locations; travelling through those spaces in the mind, they found the arguments of their speech in order. Camillo turned this inner exercise into a real object, built of wood.
His theatre was organised in seven tiers and seven sectors, governed by the seven planets then known. Unlike ordinary theatres, the spectator did not sit on the tiers but stood at the centre, where the stage lies, and looked towards the rows of seats occupied by the images. The whole of knowledge thus unfolded before the eyes of whoever entered.
Hermeticism and cabala
Into Camillo's idea flowed the most admired doctrines of the Renaissance: Ficino's Neoplatonism, the texts attributed to Hermes Trismegistus, the Christian cabala of Pico della Mirandola. The images were not simple reminders, but symbols able to connect the human mind to the order of the cosmos. The theatre aimed to be a mirror of the universe in which man, as microcosm, could recognise the structures of the macrocosm.
In the twentieth century the figure of Camillo was rediscovered thanks to the English historian Frances Yates, who in her book The Art of Memory of 1966 made him one of the protagonists of the history of mnemonics. Since then the Theatre of Memory has been cited by architects, artists and information scholars as an imaginary ancestor of systems for ordering knowledge.
Of that wooden building nothing remains, except the memory of those who saw it, a few letters and a difficult book. But Camillo's dream, to build a place in which all knowledge would be visible and walkable, continues to challenge anyone who reflects on the relationship between space, image and thought. In an age of digital archives and maps of knowledge, that small Renaissance amphitheatre seems surprisingly close.
