 It was between November 1147 and February 1148 at the synod in Trier that Pope Eugenius heard about Hildegard's writings.It was from this that she received Papal approval to document her visions as revelations from the Holy Spirit, giving her instant credence.On 17 September 1179, when Hildegard died, her sisters claimed they saw two streams of light appear in the skies and cross over the room where she was dying.
