According to a legend, whose existence can be traced back with certainty only to 1645, the little chapel of Porziuncola was erected under Pope Liberius (352-366) by hermits from the Valley of Josaphat, who had brought relics from the grave of the Blessed Virgin. The same legend relates that the chapel passed into the possession of Benedict of Nursia in 516. It was known as Our Lady of the Valley of Josaphat or of the Angels – the latter title referring, according to some, to the assumption of Mary accompanied by angels; a better-founded opinion attributes the name to a legend attesting to the singing of angels which had been frequently heard there.
