Job 28:2

Stone. Protestants, "and brass is molten out of the stone." (Haydock) --- "When brass comes out of the mine it resembles stone, and being mixed with earth is refined in the fire." (Pliny, [Natural History?] xxxvi. 27.) (Menochius) --- All this process would require much ingenuity and time. Tubalcain was a great artist before the deluge; (Genesis iv. 22.) but we cannot tell who were the inventors of these things, though (Calmet) the Greeks have specified the names of some who introduced these metals into their respective countries. (Pliny vii. 56.) (Haydock)
