The first architect, Victor Bourgeau, refused the project after studying St. Peter's, saying that it could not be reproduced on a smaller scale. At the time, the Holy See and the Papal States were threatened by the nationalist troops of Victor Emmanuel II, king of Piedmont, who was attempting to assert control over all Italy. The undeterred bishop Bourget reacted to these events by sending a total of 507 Canadian Zouaves to defend the Papal territories in Italy, whose names are engraved in gold letters on the marble slabs in the cathedral. Their motto is: "Love God and go your way." A painting depicting Colonel Athanase de Charette, commander of the Papal Zouaves, was made in 1885 by Lionel Royer. Fr. Joseph Michaud, the chaplain of the Papal Zouave volunteers of Montreal, was sent to Rome to secretly produce a scale model to work from.
