Augustine of Hippo
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 Civ. Dei, l. iii. c. 15.) This darkening of the sun it is quite plain did not happen in the regular and fixed course of the heavenly bodies, because it was then the Passover, which is always celebrated at the full moon. But a regular eclipse of the sun does not take place except at new moon.
