"And as they were singing their customary praises to out Lord, a light from heaven like a great sheet suddenly appeared and shone over them all, so alarming them that they even broke off their singing in consternation.
After a short while, this brilliant light, compared to with the noonday sun would appear dark, rose and travelled to the south side of the convent westward of the oratory and, having remained over that area for a time, withdrew heavenwards in the sight of them all.
This occurrence left no doubt in their minds that the light, which was to guide or receive the souls of Christ's servants into heaven, had also indicated the spot where their bodies were to rest and await the day of the resurrection.
So brilliant was this light that one of the older brothers, who was in the oratory at the time with another younger brother, reported next morning that the rays of the light penetrating the chinks of the doors and windows seemed brighter than the brightest daylight."
Bede, Ecclesiastical History of the English People
