"Thus, if a sunbeam, passing through a small aperure in the window shutter a, be permitted to fall upon the plane mirror, or looking glass, c, d, at right-angles, it will be reflected back at right-angles with the mirror, and therefore will pass back again in exactl the same direction in which it approached." -Comstock 1850

"The ray a, c, is the ray of incidence, and that from c, to d, is the ray or reflection. The angles which a, c, make with the perpendicular line, and with the plane of the mirror, is exactly equal to those made by c, d, with the same perpendicular, and the same plane surface." -Comstock 1850

"Plane mirrors M revolve on an endless chain placed outside of the apparatus and alter the direction of the flashes after they pass into the dark arc on the landward side so as to cause the lenses L, L to repeat their flashes over the seaward are which requires strengthening. The condensing spherical mirror and mirror of unequal areas will also be found applicable in cases where the flashes do not require to sweep over the whole horizon." —The Encyclopedia Britannica, 1910

"In order to produce, on the catoptric system, a fixed light showing all round the circle, a number of reflectors are fixed round the outside of a stationary chandelier n. As the ordinary paraboloid has about 14 degrees of divergence, twenty-five reflectors were needed to light up continuously (though not equally) the whole horizon." —The Encyclopedia Britannica, 1910

"If again the light was to revolve, then a revolving chandelier was employed having a certain number of flat faces, on each of which was fixed a number separate lamps and reflectors with their axes parallel to each other. When the chandelier revolved, and one of the flat sides was turned towards the sailor, he would, when at some distance from the shore, receive a flash at once form each of the mirrors which were on that face, but when the face was turned away from him a dark period would intervene until the next face came round again." —The Encyclopedia Britannica, 1910

"Speculum, a mirror, a looking-glass. The looking-glasses of the ancients were usually made of metal, at first of a composition of tin and copper, but afterwards more frequently of silver. The ancients seem to have had glass mirrors also like ours, consisting of a glass plate covered at the back with a thin leaf of metal. They were manufactured as early as the time of Pliny at the celebrated glass-houses at Sidon, but they must have been inferior to those of metal, since they never came into general use, and are never mentioned by ancient writers among costly pieces of furniture, whereas metal mirrors frequently are. Looking-glasses were generally small, and such as could by carried in the hand. Instead of their being fixed so as to be hung against the wall or to stand upon the table or floor, they were generally held by female slaves before their mistresses when dressing. The general form of looking-glasses is shown in the following wood-cut." — Smith, 1873
