Baltasar and Blimunda by José Saramago

LOOSE SOIL, GRAVEL, and pebbles that the gunpowder or the pick had prised from the stony ground were loaded on to the handcarts and dumped in the valley, which is rapidly being filled with the rubble blasted from the mountain and dug up from the new excavations. Heavier loads are transported on the larger carts, which are reinforced with iron plates and drawn by mules and oxen that pause only to load and unload. By means of firmly braced wooden ramps, men mount the scaffolding with the stone slabs suspended from yokes that rest on their necks and shoulders, forever be praised whoever invented the pad that lessens the pain.

These labours, as we have already said, can be described more easily because they require brute force, however, by constantly coming back to them we are less likely to forget things that are so common, and call for so little skill, that they tend to be overlooked, it is rather like distractedly watching our own fingers write, so that in one sense or another the agent of the doing remains concealed beneath the thing which is being done.
