Since the very early days of painting, frames have served to enhance the visual beauty of art. Pictures were hung on walls and they became furnishings. The first frames were often works of art themselves. They were large and elaborately carved and decorated wooden frames. There was a practical reason also. The frame framed the picture. In other words, it created a boundary that enclosed the image and separated it physically from the surrounding wall.

  As the idea of paintings as furniture began to spread, the frame became such an essential element of the entire package that the art was not considered complete until it was framed. The frame often time was more art than the painting itself. The framer was an artist in his own right. One part of his art was the carving and decoration of the frame and another was the matching of frame and picture to create a harmonious whole.

  Framing changed dramatically with the introduction of lithographs and prints. These were either original works or copies of works printed on paper rather than actual paintings on canvas. Little was understood about preservation at first and although the art prints were being framed in a similar fashion to oil paintings at first, it was soon realized that certain protection was needed. It also became common to use colored matting to frame the image inside the wooden external frame.

  As the lithograph or print became more and more popular, the art of modern framing was developed. The external frame became more than just a frame for the image, but also the platform that allowed glass to cover and protect the image and matting to enhance and create an inner frame. The use of matting inside the outer frame became another art form. Colors in the mats themselves were matched to colors in the art work to create a unified visual image. The mats, the image, the glass, and even protective backing and mounting material was all held together by the frame.

  Today, the major reason for the use of frames with art is still the original one. The frame isolates the art from the surrounding environment making it a unified piece. With prints, the frame still serves as a platform for the glass, backing, and matting. Of course, the major reason for a frame from a practical point of view is that we have become so used to them that no hanging picture would look natural without one.
