Catena Aurea · Lukasevangelium 23
And it was about the sixth hour, and there was a darkness over all the earth until the ninth hour. And the sun was darkened, and the veil of the temple was rent in the midst. And when Jesus had cried with a loud voice, he said, Father, into thy hands I commend my spirit: and having said thus, he gave up the ghost.
(de Con. Ev. lib. iii. c. 17.) What is here said of the darkness, the other two Evangelists, Matthew and Mark, confirm, but St. Luke adds the cause whence the darkness arose, saying, And the sun was darkened.
