Mons Pentelicus
About
Twenty-five separate quarries once scarred the southern slope of this mountain overlooking Athens, the same white stone that built the Parthenon centuries earlier. Roman builders began shipping Pentelic marble to Italy in the 2nd and 1st centuries BCE for temple projects far from Greece. Pausanias later reported the veins running thin, but by 117 CE the mountain was still yielding stone for Flavian-era construction underway in Rome.
What happened here
The rock is worked in benches from the top down, so that gravity does the moving. Channels are cut around a block with a pick, then it is split from the bed with iron wedges driven into a line of holes, sometimes with wooden wedges soaked to swell. Blocks are dressed roughly on the spot — no one hauls waste — and marked with the quarry, the gang, the date and the consular year, which is how the empire keeps track of what it owns. Sledges, rollers and ox teams take them to a river or the sea, because moving stone overland is the expensive part. Fine marbles are imperial monopolies. Abandoned faces still show the last unfinished cut, stopped mid-job and never resumed.
