• Refers to double pictures of the same scene that produce the effect of three dimensionality when viewed through a stereoscope. They were first envisioned in 1832 by the English physicist Charles Wheatstone, who described this as a uniquely photographic art form, since a draftsman could not draw two scenes in exact perspective from viewpoints separated only 2 1/2 inches, which is the normal distance between human eyes necessary for the three-dimensional effect. Wheatstone's mirror stereoscope was not practical for use with photographs, and the invention was not popular until the 1850s, when Sir David Brewster, a Scottish scientist, designed a simpler viewing instrument. The introduction of the collodion process, which simplified exposure and printing techniques, allowed three-dimensional photographs to become a popular craze. They may be daguerreotypes, negatives, or other forms of photographs. For images in the form of photographic prints on cards, use the more specific term

• Refers to the Christian feast and festival observed on December 25 to celebrate the birth of Jesus Christ. Its observance is first documented in Rome in 336. The practice of celebrating on December 25 began in the 4th century in the Western church as a Christian replacement for the pagan festival held on the winter solstice to celebrate the birth of the unconquered sun. The East originally gave the date of January 6 for the nativity but the date of December 25 was generally accepted by the 5th century; the Armenian Church, however, still celebrates on January 6. Christmas took on the festivity (i.e. decorations and gift-giving) of the Roman Saturnalia and other pagan festivals of that time of year. Christmas has continued to accumulate traditions over the centuries; many of the customs associated with the holiday are of non-Christian origin. Evergreens, for example, are symbols of survival and have been associated with Christmas ever since the European Middle Ages. Christmas is traditionally regarded as a festival of the family and of children. In many countries presents are exchanged in the name of or in the spirit of the holiday's patron, Saint Nicholas, or Santa Claus.
