The greeks and egyptians had transparent glass, even glass magnifying lenses.
https://en.wikipedia.org/wiki/Burning_glass "your bailiff comes,
shows me his writ - I, standing thus, d'ye mark me,
in the sun's stream, measuring my distance, guide
my focus to a point upon his writ,
and off it goes in fumo!" |
