Ancient Spectacles
It is truly astonishing how many ancient spectacles, which to collectors of such things would be veritable treasures, lie neglected and allowed to “knock about” until broken or otherwise damaged. Those mostly discovered are the heavy brass and silver-rimmed spectacles of about one hundred years ago, some very interesting specimens of which are to be seen in several of the larger local museums.
Spectacles are of very respectable age, although they cannot be traced back to the ancient peoples, for the Egyptians, Greeks, and Romans, notwithstanding that they polished glass and rock crystal and possessed much scientific lore, were ignorant of their use as aids to sight.
It is said that the credit of the discovery of how to make use of artificial aids to defective sight must be accorded to Roger Bacon, who in his book Opus Majus, published in the thirteenth century, mentioned magnifying glasses as being useful to old people to make them see better. True spectacles are said to have been fashioned in 1317 by Salvino degli Armati, a Florentine nobleman. At first they were convex; indeed, no mention of concave glasses for shortsighted persons was made until towards the middle of the sixteenth century. From that time onward there were developments, and among the household curios are to be found silver, brass, and tortoiseshell rims, and glasses of more or less utility.
