We have been given a riddle and we are completely stumped, we were wondering if anyone here could possibly help us out: "In the city of John the Baptist, there once was a very pious man.
After the fall of the house adorned with six spheres, he came into power and tried to impose his strict religious dogma onto the population of the city.
Unfortunately, the city turned on him and he was put to death, along with two of his brethren, in front of a very famous building.
That building will lead you to the next step." (We believe the building's name will give us a password to continue with an ARG we're trying to solve currently) Thank you for your help.
We suspect that the "house" referred to in the second line is the House of Medici, by the way.
