This year I will be in Lucca on Good Friday, March 30, with a family group of seven adults. As you might expect, a religious procession is usually held on that day, and I have read that the participants sometimes wear historical garb. That rings my bell!
I attended a (very long) religious procession in L’Aquila in 2004, the Perdonanza. Here are a few photos, culled from more than 300, which showed the costumes I especially liked. Because the Perdonanza recognizes a medieval event, while Good Friday recalls ancient/Biblical times, the clothing will likely be different. Regardless, I plan to be there taking photos and contemplating those ancient events.
These are pre-earthquake photos of L’Aquila. Hope you enjoy them!
