The protocols of sacred memory are carved in stone. Four Doors is an architectural mnemonic—a collection of portals to my research on monastic memory practices. It’s inspired by the Latin inscriptions above the four doors of the seminary-turned-hotel where Summer of Protocols researchers met for our in-person retreat. Medieval monasteries were high-tech “machines for thinking”. They functioned as an extension of the monks’ minds and played an important role in their memory protocols. Four Doors invites you to step through each entryway, into a room full of reflections on what happens when we become the buildings we behold.
