At the 13th International Architecture Exhibition — Venice Biennale, Tod Williams and Billie Tsien have conducted a fascinating Wunderkammer experiment on the human personality at the Arsenale. In a rundown building at the end of the exhibition route, in the Giardino delle Vergini, the two American architects have amassed an array of different objects owned by a group of 35 architects from all over the world.

More than simply objects, these are "creative talismans" that accompany the architects in their professional life. Each architect was sent a box, and asked to return it filled with the "unlikely and sometimes mundane objects" that inspire their production. Peter Zumthor put together a number of coloured jars, whereas Shigeru Ban revealed he carefully recycles old photocopies and emails, assembling them into fine, handmade sketchpads.

Bijoy Jain of Studio Mumbai constructed a sort of altar — a wooden casket lined with photographs — containing a number of small buildings in cast bronze and a video describing life in Indian villages. There are also travel memories (and perhaps a desire for a different life) in 1a href="https://www.odonnell-tuomey.ie/" target="_blank">Sheila O'Donnell and John Tuomey's box: a blue chair, like those found in Greece, wax pastels, watercolours of a small church, pebbles and a dried flower. The stones amassed by Toyo Ito in his box are also memories: pieces of rubble gathered in the village of Sanriku, destroyed by the tsunami on 11 March 2011.

My personal favourite is Diébédo Francis Kéré's box, filled with the red soil of his country, Burkina Faso, and a rudimentary wooden tool for beating it. Nothing more, but probably the origin behind many things. Laura Bossi
