BOOK VI.
Digging of veins I have written of, and the timbering
of shafts, tunnels, drifts, and other excavations,
and the art of surveying. I will now speak first of
all, of the iron tools with which veins and rocks are
broken, then of the buckets into which the lumps
of earth, rock, metal, and other excavated materials
are thrown, in order that they may be drawn, con
veyed, or carried out. Also, I will speak of the
water vessels and drains, then of the machines of
different kinds,1 and lastly of the maladies of miners. And while all these
matters are being described accurately, many methods of work will be
explained.

There are certain iron tools which the miners designate by names of their
own, and besides these, there are wedges, iron blocks, iron plates, hammers,
crowbars, pikes, picks, hoes, and shovels. Of those which are especially
referred to as “iron tools” there are four varieties, which are different
from one another in length or thickness, but not in shape, for the
upper end of all of them is broad and square, so that it can be struck by the
