Included among the rarest and therefore most desirable eyeglass frames are those made of whalebone. Baleen, as it is also referred to, is a tough, springy, horny, keratin-like material which forms fringed plates that hang from the palate (upper jaw) of the baleen whale. Baleen grows throughout the whale's life and there can be as many as 400 plates per whale. These hairy plates are sieve-like, used to strain and filter plankton, krill, and other small organisms from the water. The collected food is then wiped off by the tongue for swallowing. Baleen whales (whalebone whales, Kingdom: Animalia, Phylum: Chordata -vertebrates, Class: Mammalia - mammals, Order: Cetacea, Suborder: Mysticeti) can, in this manner, be distinguished from other whales which instead have regular teeth. These "great whales" are distinguished as the largest animals on earth. Baleen whales have two blow holes, the females are even larger than the males, and many are endangered because of over-hunting. Whales hunted by Europeans and Americans for baleen and oil were of several closely related species and sub-species. They included: 1). North Cape whale (coast of Norway; since
before the 10th century. In the Medieval, Renaissance, and Baroque eras, most baleen products were from whales hunted by Vikings in coastal waters; and by French and Spanish Basques, both in coastal waters and far up in the open sea of the North Atlantic. After 1610 the harvest was increasingly from the High Arctic, primarily Dutch but also English, Scottish, Scandinavian, Basque, French, and German. Once the Americans got into the act and developed a pelagic
South Sea whale fishery (early-to-mid 18h century) -- they were followed by
others in the 19th century -- the prevailing baleen prey species shifted to the
Southern right; and when the American fleet finally reached the Western Arctic
in the middle 19th century, bowhead baleen rapidly took over. Whalebone was also
the most important product of San Francisco’s Arctic whale fishery. Many of the baleen eyeglass frames seen in advanced collections probably date from the late 17th to the very early 19th century. As expected nose spectacles were the earlier examples and temples spectacles were generally then made during the second half of the 18th century. The material is durable and light weight and therefore an excellent substance for the construction of the eyeglass frame. Whalebone is easy to carve and shape since it has a pliable almost plastic-like property. As such it was used in various manufacturing industries as a forerunner of plastic. Horn and baleen are difficult to distinguish from one another, but in fact they are really quite different macroscopically. Horn comes from a cow while baleen is from a whale. Horn is found in many colors from near white to black, while baleen is typically dark grey or nearly black (some light plates have now been seen at the San Francisco Maritime Museum). Baleen is sometimes seen as cream or even white. If your warm horn it produces a strong smell and it is impossible to bend a piece of horn into the form of baleen spectacles. Finally it is impossible to use baleen to make a Martin’s Margin insert ring, which usually is horn. Microscopically it is nearly impossible to distinguish horn from baleen (or from tortoise shell) on any basis other than morphology or DNA. A PhD dissertation at University of Cologne, Germany) circa 1997 by demonstrated conclusively that baleen, horn, and tortoise shell are structurally identical and indistinguishable in micro scale. Even the most advanced collections may have only one example of an optical object made from baleen. A large group (six nose spectacles) exists at the Luxottica Museum in Agordo, Italy and are truly wonderful to behold in person. Enjoy all the other images in the slideshow that follows.
