7 Another report from these remote provinces announced to Dome the glory of their deeds. And so, when Pope Nicholas I ordered the brothers to Rome, they obeyed without hesitation. They began their Roman journey quickly, bringing with them the remains of St. Clement.

The body of St. Clement was brought with great portents into the basilica constructed at the time of Constantine, in the very tracks of the ancestral home of that invincible martyr.
