extract from Lucretius’ poem ON THE NATURE OF THINGS

And yet it is hard to believe that anything
in nature could stand revealed as solid matter.
The lightning of heaven goes through the walls of houses,
like shouts and speech; iron glows white in fire;
red-hot rocks are shattered by savage steam;
hard gold is softened and melted down by heat;
chilly brass, defeated by heat, turns liquid;
heat seeps through silver, so does piercing cold;
by custom raising the cup, we feel them both
as water is poured in, drop by drop, above.
