Original: Additionally, he left an endowment for the performance of his late motet, Pater noster/Ave Maria, at all general processions in the town when they passed in front of his house, stopping to place a wafer on the marketplace altar to the Holy Virgin.
Simplified: There was a statue of the Blessed Virgin Mary on the wall of his old house, and when church processions passed by they stopped in front of it and sang Josquin’s motets Pater Noster and Ave Maria.
