The Church of the Holy Sepulchre constructed 327-330 AD. Eusebius provides a description of what was seen when excavation of the tomb was complete and those individuals present saw. It sounds like a human figure like the Shroud of Turin has.
In his book, The Life of Constantine Book 3 Chapter 28, Eusebius wrote about the discovery of the Holy Sepulchre:
This also was accomplished without delay. But as soon as the original surface of the ground, beneath the covering of earth, appeared, immediately, and contrary to all expectation, the venerable and hollowed monument of our Saviour’s resurrection was discovered. Then indeed did this most holy cave present a faithful similitude of his return to life, in that, after lying buried in darkness, it again emerged to light, and afforded to all who came to witness the sight, a clear and visible proof of the wonders of which that spot had once been the scene, a testimony to the resurrection of the Saviour clearer than any voice could give.

and then find “Most Holy Sepulchre” in the text or scroll down roughly 3/5 of the way.

Also, when I looked at pictures inside the Edicule there appears to marble on top of the bench where Christ’s body must have been laid.
I wonder if the marble was lifted up we could see a blood stain that matches the blood stain on the shroud. I doubt anyone would lift the marble to check…but someday I believe it should be done since it would not permanently damage anything.
