marmoreal days... opened into the hill a spacious wound, and digged out ribs of gold


                           ...his looks and thoughts

Were always downward bent, admiring more
The riches of heaven’s pavement, trodden gold,
Than aught divine or holy else enjoyed
In vision beatific. By him first
Men also, and by his suggestion taught,
Ransacked the centre, and with impious hands
Rifled the bowels of their mother Earth
For treasures better hid. Soon had his crew
Opened into the hill a spacious wound,
And digged out ribs of gold…
