Irrespective of the statements by Paul M. G. Levy and the recent reconstruction by Susan Hood, crediting Arsène Heitz with the original design still seems to me the soundest option. In particular, Arsène Heitz himself, in 1987, laid claim to his own role in designing the flag and to its religious inspiration when he said that 'the flag of Europe is the flag of Our Lady' [Magnificat magazine, 1987]. Secondly, it is worth noting the testimony of Father Pierre Caillon, who refers to a meeting with Arsène Heitz. Caillon tells of having met the former Council of Europe employee by chance in August 1987 at Lisieux in front of the Carmelite monastery. It was Heitz who stopped him and declared "I was the one who designed the European flag. I suddenly had the idea of putting the 12 stars of the Miraculous Medal of the Rue du Bac on a blue field. My proposal was adopted unanimously on 8 December 1955, the Feast of the Immaculate Conception. I am telling you this, Father, because you are wearing the little blue cross of the Blue Army of Our Lady of Fatima".
