Note 12 — PART VI.
Charles Lock Eastlake translation
In the Treatise De Igne, by Theophrastus, we find the same notion thus expressed: "Brightness (τὸ λευκὸν) seen through a dark coloured medium (διὰ του μέλανος) appears red; as the sun seen through smoke or soot: hence the coal is redder than the flame." Scarmiglione, from whom Kircher seems to have copied, observes:—"Itaque color realis est lux opaca; licet id e plurimis apparentiis colligere. Luna enim in magnâ solis eclipsi rubra conspicitur, quia tenebris lux præpeditur ac veluti tegitur."—De Coloribus.
