Cut the radicchio into fine strips, divide the artichokes into sixths (or only quarter depending on size) and place both in a large bowl.
For the marinade, finely chop an egg, onion and capers. If you don`t like capers, you can also use pickles. Mix vinegar and oil, add salt, pepper and the chopped ingredients. Mix well or shake well in a shaker. Mix the salad with it.
Divide the salad between 4 plates or serving bowls. Cut the remaining 8 eggs into wedges or slices and place 2 eggs each on a salad.
