Which of course makes sense if one is trying to view the internals of the shaft, but not for providing lighting for the room itself.
My take on Greaves' observation is that if there was that much soot in the shaft, the "blackness within it" either was caused by a short term insertion of a candle, torch, or lamp to briefly inspect the structure of the visible length of the shaft, or is an indication that the shaft originally was related to a combustion function.
Also, be aware that Greaves came from a time when the standards of scientific investigation were far lower than they are today. Greaves' powers of observations leave much to be desired in his descriptions. One look at his illustrations shows the limits of his standards of precision, accuracy, and thoroughness. As I recall, he makes no mention of the portal at the top of the GG leading to Davison's chamber which presumably was there when he visited in the 17th century. But Greaves' volume was an important early contribution beginning to what has turned into an enormous field of study.
How can any of us ever know, when all we can do is think?
