Cyril of Jerusalem
Catechetical Lectures, 347-348 AD
Bishop Cyril, who administered his baptismal catecheses before the Tomb of the Holy Sepulchre in the middle of the 4th century, left in his writing traces of descriptions of the important construction that Constantine’s architects had designed to honor the place of the Resurrection.
Of the excavations carried out in order to build the Edicule around the empty Tomb
For now it is not to be seen, since the outer cave was cut away at that time for the sake of the present adornment. For before the decoration of the sepulchre by the royal munificence, there was a cave in the front of the rock. But where is the rock that had in it the cave? Does it lie near the middle of the city, or near the walls and the outskirts? And whether is it within the ancient walls, or within the outer walls which were built afterwards? He says then in the Canticles: in a cave of the rock, close to the outer wall.

Of the Cross at Golgotha
He was truly crucified for our sins. For if thou wouldest deny it, the place refutes thee visibly, this blessed Golgotha, in which we are now assembled for the sake of Him who was here crucified; and the whole world has since been filled with pieces of the wood of the Cross.

On the Baptismal rite in the Constantinian Church
After these things, ye were led to the holy pool of Divine Baptism, as Christ was carried from the Cross to the Sepulchre which is before our eyes. And each of you was asked, whether he believed in the name of the Father, and of the Son, and of the Holy Ghost, and ye made that saving confession, and descended three times into the water, and ascended again; here also hinting by a symbol at the three days burial of Christ.
