But was it possible to come all the way to Rome and not go down into the Colosseum? For me it was impossible!... I saw what I was looking for and I cried to Celine: "Come quick! We can get through!" We crossed the barrier...we were climbing down over the ruins which rumbled under our feet...the guide...had pointed out a tiny bit of pavement marked with a cross as the place where the martyrs fought,...We soon found it and threw ourselves on our knees on this sacred soil...My heart was beating hard when my lips touched the dust stained with the blood of the first Christians.
