On the north flank of the Circus Maximus, where Roman emperors presided over breakneck chariot races, there is a small and unassuming message affixed low on a brick wall. It doesn’t commemorate a historic event or a work of art. It bears just three short Italian words and a date: “Mi sono perso. XVII-IX-MMX”: “I am lost. September 17, 2010.”
The plaque is easy to overlook, but it has attracted the attention of many who are surprised, perplexed, and touched by it. One individual was moved to contribute the less enigmatic “PU” in green paint.
