"Piè di marmo" ("Marble foot"), also known as "Piedone" ("Big foot"), was probably part of the statue dedicated to Isis located inside an old temple dedicated to the Goddess. It was originally located at Via Piè di Marmo but it was moved to Via Santo Stefano del Cacco in 1878 to not cause an obstruction during the funeral procession in honor of King Vittorio Emanuele II directed to the Pantheon. Since then, a lot of tourists have been taking pictures of that old strange sculpture.
