"By means of [the microscope and the telescope] man touched, one might say, the two infinities. With the aid of glass, he could contemplate at his leisure the mite and the ring of Saturn. […] Master of glass through fire, and master of light through glass, he had lenses and mirrors of all kinds, prisms, containers, beakers, tubes, and finally barometers and thermometers. However all this originally began with the astronomical lens, which honours glass; and physics is born in some manner from astronomy, as it was written that, even in a material and gross sense, all science must descend from heaven."
